Caution: If you want to take Javik along on this Mission, you'll have to complete Priority: Palaven first.
Completing it: Go to Sigurd's Cradle: Decoris System, and Land on Sanctum. Before you do anything, get all the loot. Clear the area, then wander around and find a Sniper Rifle Enhanced Scope Mod, Pick Up Credits from three consoles, loot a Medical Station, Read two Journal Entries, and find the Failed Medi-Gel Experiment for the Mission Citadel: Alien Medi-Gel Formula.
Next, your goal is to pick up two Artifacts. Go to the first one and deactivate the containement field on it, then pick it up and take it back to the shutle. Several Cerberus goons will attack you. When they're dead, pick up the second Artifact. When you do, Cortez will be attacked and will have to leave for awhile. At the same time, you have to fend off endless waves of enemies until he can get back. When you hear that he's ready for you, ignore the remaining enemies and make a bee line for the shuttle.
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: Scan a computer during the Mission N7: Cerberus Lab. Return to the Hospital on the Citadel and turn them in to the female doctor to the left as you exit the elevator.
Go to Exodus Cluster: Utopia System, and Land on Eden Prime. Liara is required to be in your squad (she is the Prothean expert, after all), so choose your other squadmate, if you have a choice. The dialog will of course vary depending on who you chose. Go in the building on the right. Salvage the Computer for some Credits and loot the Med-Kit. There is also a Terminal here that will trigger the Mission "Eden Prime: Resistance Movement". This must be completed before returning to the Normandy, otherwise it gets stuck in the Journal for the entire rest of the game.
Follow the Nav Point and Use the Elevator Console. This will trigger a cutscene, and a new pair of objectives, which may be completed in either order. (Make a hard save before picking up the first one, as there is a crash bug on one of the pieces of data, so if your game crashes, just go pick up the other piece first.) Several enemies will be dropped off. Kill them, then go in the building on the left to find a Terminal with some Intel on it and some Equipment you can Salvage for Credits.
Go towards the next building on the left and you'll be attacked by more Cerberus troops. You can go up the ladder to gain the "high ground" advantage, if you like. Inside the building you'll find another Terminal with more Intel on it, as well as a Med-Kit and some Equipment to Salvage for Credits.
Go towards the fresh Nav Point that Liara puts on your HUD. Bypass the door, and inside you'll find a Med-Kit. In the second door, Use the Computer Console to trigger a cutscene where you get the activation code for the Pod.
Leave this building and go left, up some stairs and into another building. As you go out the other side, you'll be attacked by Cerberus troops. Clear them out, and follow the Nav Point across the courtyard and into another building. Salvage some Equipment on the table to the left for some Credits, then go through the inner door to find the data for how to open the Pod.
After the cutscene, several shuttles drop off their troops to attack you. Your best bet is to use the buildings to your left for cover. Beware the Turrets dropped by Engineers. Once the area is clear, Liara will mention that the bridge you came across on has been retracted. Before you find the alternate way back, be sure to scour the area for any loot or Intel you may have missed for the "Eden Prime: Resistance Movement" Mission, as there's no coming back.
Hop down this end of the retracted bridge, then go across and up two ladders. Hop over the two vents straight ahead, and go down the ladder to the right. Make your way to the Stasis Pod and Activate it. While you wait, you should pass the time by killing Cerberus troops. An Atlas will drop in at one point. If you want the Hijacker Accomplishment, shoot the cockpit to kill the pilot, then get in before any other Cerberus troops can take his place. Also, you'll want to either let your squadmates die, or position them out of the way so they don't shoot the Atlas. During the fight, your squadmates will mention a building with extra ammo in it, should you need any. After the area is clear, the Pod will open, and you'll meet Javik.
Through cutscenes, you'll wind up back on the Normandy. After your conversation with Javik, you'll have the Particle Rifle assault rifle available to you. Javik will be available as a squad member, but not until after you've completed Priority: Palaven. For now, explore the ship and get people's reaction to having a living Prothean on board.
WARNING: Must be completed within three misisons of becoming available. Otherwise, if Jack survived ME2, you'll be forced to fight her during Priority: The Citadel II.
Completing it: Go to Petra Nebula: Vetus System and Land on Grissom Academy. After the cutscene, go through the door ahead and kill the Cerberus troops. When the area is clear, Examine the damaged door to start a conversation with the headmistress, Kahlee Sanders. The dialog is interrupted at the end by news of Cerberus continuing to threaten the students. Proceed through the next door, where you'll see a student being dragged away. There's nothing you can do about that, so continue. Over the barrier to the right you'll find an Assault Rifle Stability Damper Mod.
Through the next door, you'll see two Cerberus troopers with their backs to you. Kill them, then Examine the DataPad on a couch around the corner to the right for some Credits. Talk to the boy you just saved, then continue through the next door. Examine the Tactical Analysis Review on the desk ahead, pick up the SMG Heat Sink Mod in the desk in the middle of the room, and Read the Personal Log on the desk at the right end of the room.
Go through the next two doors and kill the Cerberus troops who enter through the far side of the room. The room to the left has the M-22 Eviscerator shotgun. Go through the hallway on the other side of the previous room and on the right side of the couches is the M-96 Mattock assault rifle. Continue to the right to find a Locker with some Credits in it, then backtrack to the hallway to pick up the Mnemonic Visor. Do all this, then Talk to Seanne Bellarmine, quickly, because she keels over and dies if you take too long.
Through the next door is Orion Hall. Before going through the door, you can shoot the generator that's powering the Cerberus Logo above the door. This gives Ms. Sanders access to the PA. So instead of Cerberus announcements, you get to hear her. Go through and you'll meet the surviving students, and if Jack survived ME2, she'll be here as well. The reunion gets cut short when several Cerberus troops, including an Atlas, attack. Kill them before the student's biotic barrier is destroyed (shown by a blue bar in the upper right of the screen).
After the fight, you'll enter into dialog with the students, and possibly Jack. Being nice to her allows you to carry over a romance from ME2, though in a limited fashion. Once you're done talking, the students will be in the control room on the upper level. Look around for some loot: Relative to where you came in, on the near right you will find a Data Log. In the far back right you will find a Med-Kit. Your first goal is to find a laptop, which is to the left from where you came in. There is a DataPad next to it. In the upper room with the students, you'll find an Assault Rifle Precision Scope Mod in the back of the room, and a DataPad in the front of the room. When you're ready, Use the Door Override Controls to open the door below. Opening it starts a conversation with Jack and the students.
Through this door is a large courtyard with plenty of places to take conver. Several waves of Cerberus troops will attack you, along with an Atlas on the far side. Also beware the Turrets placed by Engineers, and the shield pylons, which are hard to get to. Once the area is clear, go through the door on the lower level. In the hallway, you'll find a Mission Brief on the chairs on the left and a Med-Kit. Then get some Credits off the computer on the left. Save, then go through the next door. This puts you on the other half of the courtyard, and in combat with several more waves of enemies. Ememies will also appear on the wall directly above you. You might consider returning to the other side, as they're not smart enough to follow you, and you can pick them off from a distance.
Through the next door, kill the enemies you see, then Access a Computer Terminal for some Credits. Talk to the student you just saved. If you chose to save David in the ending of the Overlord DLC during ME2, he will thank you and unlock the door nearby for you, and inside you'll find the M-96 Matlock or M-22 Eviscerator and a Sniper Rifle Piercing Mod. Through the next door, be sure to pick up the Biotic Amp Schematics from the Terminal on the right, for the Mission Citadel: Biotic Amp Interfaces. Through the next door, pick up the Serrice Council Chestplate from the couch on the left.
Go through the next door and kill the Cerberus Enginner. Find a Med-Kit on the couch to your right, and Access the Data Log nearby for some Credits. Get in the Atlas and proceed up the stairs into the next large room, where you get to pick off several waves of bad guys. If the Atlas explodes with you in it, you'll die and will have to start from your last save. When the area is clear, pick up the SMG Magazine Upgrade Mod on a bench near where you entered the room.
When you're ready, go out the exit. If Jack didn't survive ME2, one of the students will die. You'll then get a morality choice about what to do with the students. Using them on the front lines gets you a few more points of War Assets than using them as support. The cutscene continues as you speak with Anderson on the Vid Comm. Explore the Normandy for your crew's reactions.
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: During Grissom Academy: Emergency Evacuation, after saving the student with the tech shield, search a Computer Terminal in the next corridor. If you miss them, you can buy them from the Spectre Store. Next time you're on the Citadel, turn them in to the Asari next to the elevator in Huerta Memorial Hospital.
Completing it: After you've Scanned the planet in question, when Purgatory Bar becomes available for you to visit, go there and hand it in to the Turian.
Completing it: Go to the Presidium Commons. On the east side of the Apartments, there's a Nav Point on a Door you can Open. Doing so starts a scene where you meet with Narl. Regardless of how you respond to his plan, you go along with it. The Mission is complete at the end of the conversation. You may return to Aria, if you wish, to learn what you've gotten.
Completing it: Go to the Docks: Holding Area and Talk to Darner Vosque near Cargo Hold A. He wants the Turian General Septimus Oraka killed. Regardless of your response, you have two ways to complete this. Go and Talk to the General, who's lounging in the middle of the Presidium Commons.
1) At the end of the conversation, choose [Put a hit on him] for Renegade Points.
2) The Paragon option is a bit more round-about. He says he needs weapons, but the Salarian over at Cipritine Armor won't sell him the good stuff. Agree to help him. Talk to the Salarian Kannik to learn that he wants an artifiact. Go to Kite's Nest: Vular System and Scan planet Vana. You'll get a War Asset, and the green Mission Tag will remain, but that's enough. Return to Kannik, then Talk to Oraka to complete the Mission.
Completing it: First, Talk to Commander Bailey in his office in the Embassies. Next go to the Presidium Commons and Talk to the C-Sec Assistant in the outpost to start a conversation with the Eclipse leader. She is a bit nuts, so you have two choices here:
1) At the end of the conversation, tell Bailey to release her anyway.
2) Promote her second in command by going to Docks: Holding Area, Cargo Hold A, and Talk to Sayn, a Salarian who's just sitting there dejectedly. You can ask him to leave his former boss in jail or kill her upon her release. The Mission won't complete until you approach the elevator on your way out, and you talk to Bailey on your comms.
WARNING: Must be completed before starting Priority: Tuchanka.
Kasumi will mention Jacob, but this mission becomes unavailable before you see him.
Completing it: Meet Jondum Bau just outside the Spectre Office at the Embassies. If Kasumi Goto was recruited and survived ME2, he'll drop her name, and she'll meet you as you walk into the Spectre Office. She'll also have some dialog as you continue the Mission. Use the Spectre Terminal, click the "Hanar Embassy Tracking" item, and choose the "Enable" option.
The first place you need to go is the opposite end of the Embassies. There, you'll find a Terminal to Bypass. Next, go to the Docks: Holding Area. Just off the Elevator is another Terminal. Bypass it to listen to the next conversation. The third Terminal is at the opposite end of the Docks. Once you've used that, return to the Terminal next to the Elevator. Lastly, go back to the first terminal in the Embassies to meet up with Bau.
If Kasumi didn't survive ME2, you'll have to choose between saving Bau or stopping the upload. Choosing one gives you the corresponding War Asset, and saving the Hanar Homeworld is worth more points. If Kasumi is there, she'll stop the virus upload, and you'll get both the Spectre Unit War Asset, and the Hanar and Drell Forces War Asset. If she was loyal at the end of ME2, she'll be gained as a War Asset as well.
Completing it: After you've Scanned the planet in question, when Docks: Holding Area becomes available for you to visit, go there and hand it in to the Batarian Preacher.
Completing it: After Priority: Palaven, go to Shrike Abysal: Urla Rast System, and Scan Talis Fia. Return to the Volus to give the artifact to him.
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: Go to the Krogan DMZ: Aralakh System, and Enter Orbit around Tuchanka Select the Downed Vessel Site. After the cutscene, proceed forward and pick up the SMG Magazine Upgrade Mod on the left. Then climb up the ladder. Proceed forward to the three Husks and kill them. Then Salvage the Spare Parts and climb up the next ladder. Continue forward, jump over the gap and pick up the M-9 Tempest SMG next to some dead turians near a crashed turian escape pod.
Continue forward and you will get a chance to ambush three Cannibals. While you are fighting them two more will appear. Once they are all dead, a Harvester will appear. It will flee once about 75% damaged. You may be able to kill it, but if you do, you may trigger a bug that prevents completing the mission. Drive it off before it takes out the escape pod for a bonus 300 experience, plus compliments from your team. You can't get across to where the turians were, so turn right and climb up the ladder. At the top, just to your left will be a Sniper Rifle Spare Ammo Mod. Hop down off the ledge. Continue forward to Salvage some Spare Parts, then backtrack slightly and take the path that was to your right. On the ground ahead of you is the Phaeston assault rifle. Keep going forward and turn left at the dead-end T-junction to pick up an SMG Ultralight Materials Mod. Return back to the other hallway and go down the ladder.
Head straight ahead and pick up the Med-Kit on the right, across from a dead turian. Keep going forward and around the corner. Sneak up on the Marauder and Cannibals and take them out. Again a Harvester will fly in, this time dropping off some husks for you to fight. Chase it off or kill it, as this one won't cause a bug. Again, since you can't get to the turians, turn right and drop off the ledge. Lieutenant Victus will come in over comms asking about your ETA. Proceed forward and pick up the Hahne-Kedar Chestplate on your left. Another drop down and you will find a Flight Recorder on the ground on the right to Listen to. Slightly farther ahead on the left will be a Shotgun Smart Choke Mod. As you approach the open area, another Harvester will drop some husks and fly off, probably too quickly for you to kill. Take out the husks and Salvage the Junk on the dead turians before going down the ladder.
Another Harvester will then drop off some Cannibals. Take them out and chase or finish the Harvester off. Continue forward, down the ramp and around to the right to find a Med-Kit on the ground near a fire. Then drop off the ledge to pick up a Sniper Rifle Extended Barrel Mod. Keep dropping down around to the left and you will see some combat in the distance. Move forward as the Harvester drops off more Reaper forces. Move forward along to the right to find a Reaper Blackstar heavy weapon with which to make short work of the Harvester. Finally move forward to begin a conversation with Lieutenant Victus. Get him to rally his troops however you can, and you'll be back on the Normandy. When speaking with the Primarch, he still refuses to come clean about the Bomb. Talk to everyone else on the Normandy to get their reactions.
WARNING: Must be completed within three misisons of becoming available. Not completing this mission within the three Mission limit results in a 300-point reduction of the Krogan War Asset, and both Eve and a significant portion of the krogan population die from the explosion.
Completing it: Go to the Krogan DMZ: Aralakh System, Enter Orbit around Tuchanka, and select the City Ruins - Locate Bomb. As you land, fight your way through the Cerberus soldiers and explosions to the ruined building ahead. The fighting and explosions will stop, so go through the break in the wall and head up the ramp to your left. About halfway up the ramp to the next floor, on the left hand side, you will find the M-29 Incisor sniper rifle.
Proceed up the ramp and pick up the Shotgun Blade Attachment Mod. Once you round the corner, Cerberus troops will attack from behind shield generators. At the end of the hall on the far right, you will find the Rosenkov Materials Gauntlets. Head to the far left end of the room, and before you turn around find a Console to Salvage. Head up the rubble and when you go around to the left you will find an SMG Heat Sink Mod in the corner on the floor around where Lt. Tarquin Victus notifies you about Cerberus putting up a fight. Then, around the corner, more Cerberus troops appear. After the battle, head down the room and once you get past the open pit on your left, you will find a Med-Kit and a Pistol Scope Mod along the far wall in the next room.
As you climb out of the building, two Cerberus troops are being evacuated; if you act quickly, you can kill them. Cross the bridge to where the troops were, and Salvage the DataPad. As your turn the corner, there are more Cerberus Assault Troopers to deal with, but, as you make your way through them, more are being evacuated. Make your way up the ramp, and take a look at the Bomb Site, and then head up the ladder to your right. Straight ahead, against the wall, is a Sniper Rifle Concentration Mod. A little farther along, you will find a Pistol Melee Stunner Mod. On the left-hand side, you will find Turian Technology to Salvage. Pick up the Med-Kit, and partway up the crates you'll find the Turret Control Schematics for the Mission Citadel: Cerberus Automated Turret Schematics.
Continue around the corner and down the ladder to trigger a cutscene with Lt. Victus. After the cutscene, you must defend Lt. Victus from Cerberus while he disables the Bomb. There is an M-560 Hydra heavy weapon in the near-right corner, which you can use against the Atlas. Once all Cerberus forces have been dealt with, another cutscene begins. You'll wind up back on the Normandy in conversation with the Primarch and the Urdnot. Diffuse their argument how you will, then explore the ship to hear the reactions of your crew.
Completing it: Buy the E-Gel Thermal Conduit from the Elkoss Combine Arsenal Supplies store in Presidium Commons, or from the store on the Normandy. Talk to Engieneer Adams to learn they're being installed. Return to him after another Mission to learn it's done. If Kenneth and Gabby survived ME2 and you pardoned them through the Spectre Terminal on the Citadel, you'll get an extra War Asset.
There is a minor bug here where, instead of waiting until after another Mission has been completed, you'll have this conversation immediately, but you won't get the War Asset. After you do actually complete another Mission, Traynor will mention that Adams wants to talk to you. Do so, and you'll have the same conversation again, only this time you will get the War Asset.
Completing it: Talk to Wrex/Wreav. Go to Ninmah Cluster: Mulla Xul System, and Land on Utukku. During the cutscene, you'll meet up with Grunt, if he survived ME2; otherwise it's Urdnot Dagg. When you gain control of Shepard, search the structure on your left for the M-300 Claymore shotgun, a Pistol High Caliber Barrel Mod, and Spare Parts that you can Salvage. Further down the slope you come to a cluster of krogan structures. Enter the leftmost building with the Weapon Bench to find an SMG High Caliber Barrel Mod. Outside you'll find Spare Parts to Salvage.
Talk to Grunt/Dagg before entering the other building on the right. Once inside far enough, the building will fall down to the level of the tunnels and you will not be able to get back up to the krogan squad. You can only proceed forward, where you will find the body of a krogan scout and your first M-451 Firestorm heavy weapon. Burn the first Webbing, then drop down over the ledge and burn some more Webbing. (If you run out of ammo for the firestorm, webbing can still be destroyed with abilites or normal weapons.) Past the ledge and a few more Webbings on the left, you will find Spore Pods. You need to destroy them from a distance or they will explode when you get near them and damage you. Continue on and go up the ramp to find more Spore Pods, and in the hollow behind the second Webbing another dead krogan scout with another Firestorm. Continue through the blue glowing goop, take out a Webbing, and drop down again.
You will then fight some Reaper troops. Once the area is clear, you can find a Shotgun Shredder Mod along the left-hand wall. Proceed across the room, along the right is another scout next to some ammo, and in the center is a scout next to a Firestorm. At the top of the ramp are a lot of Spore Pods. You will pass a blocked door on your left, and past more Webbing will be a Reaper Node that you need to destroy to open the door. Take out the Webbing past the door and the ceiling collapses, trapping you on the far side. The path splits, but both directions take you to the same place. Take out the Webbing on the left so you can Salvage some Reaper Tech for Credits.
Continue forward and a husk will charge toward you. Take out the Webbing on the left to find a Krogan Corpse that will give you the Mission Citadel: Krogan Dying Message, though it may not appear in your Journal. The second Webbing on the right will have another scout behind it with a replacement Firestorm. Drop down into the large area ahead, and kill some Reaper troops. Head across the room and more enemies will appear. Before you go down the ramp, pick up the Shotgun Spare Thermal Clip Mod. Drop down over the ledge.
The pods are now Gestation Pods, and in addition to exploding, will relase Swarmers. Take out the pods on the left, Salvage the Reaper Tech for some Credits. Keep moving forward, taking out pods. You will find another Firestorm next to a dead krogan. Jump across the chasm, take out some more pods, and further up the hill, after a conversation, next to another dead scout you will find the Ariake Technologies Shoulder Guard.
Climb up a series of ledges taking out the Pods as you go. Jump across a second gap and head down the hill to where you will see Aralakh company holding off reaper forces. Take out the nearby Pods and the Webbing and then destroy the Reaper Node. You'll get a cutscene where you meet up with Grunt/Dagg. Make sure to pick up the Med-Kit and the Pistol Piercing Mod before leaving the room. You can also replace your Firestorm.
In the next room, behind the clutch of pods on the right is more Reaper Tech to be Salvagedfor Credits. Examine the Narrow Passage to get another cutscene. Reaper fortifications will then extend upward out of the ground and block your forward progress. To lower the walls, you must destroy three Reaper Nodes. The first is directly above you. The left wall will retract once disabled, so be prepared to fight the waiting Reaper forces. Once they have been defeated, proceed toward where they were and disable a second Reaper Node, retracting the second set of the barriers. Here you can also pick up another Firestorm. Double back and exterminate the two groups of Reaper forces before destroying the third and final Reaper Node. Fight against one last wave of Reaper forces; once they have been defeated, you get a cutscene.
If you saved the Rachni Queen in ME1, you will speak to her during this cutscene. If not, you will converse with the Breeder, a different rachni individual who was revived by the Reapers and has become indoctrinated. Either way, you may choose to either leave her or help her to survive. If you leave the Rachni leader to die, you will gain Aralakh Company as a War Asset worth 25 points, but no Rachni Assets. If you chose to rescue the original Queen from Noveria, Aralakh Company will suffer grievous losses in the holding action, reducing their strength by 25 points. However, the queen provides Rachni Workers worth 100 points in War Assets. If you choose to rescue the new Breeder, you gain the Aralakh Company and 100 points of Rachni workers; however, the Breeder proves untrustworthy after a few missions, taking away her war asset, wiping out Aralakh Company, and removing 100 points from the Alliance Engineering Corps.
No matter what you chose with the Breeder or Rachni Queen, Grunt or Urdnot Dagg will stay behind to hold off Ravagers while Shepard's party runs for the shuttle. Grunt can survive this if he was Loyal in ME2, and adds 50 points to Aralakh Company's War Asset. Back on the Normandy, speak with everyone, buy stuff, and upgrade weapons.
Completing it: Go to the Presidium Commons and give it to the Asari Ereba at the Citadel Gift Shop in the Meridian Place Market area.
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: Liara points you to Barla Von in the western "banking" end of the map. Talk to him to get the location. Go to Krogan DMZ: Dranek System, and Scan the planet Rothla to find the Shadow Broker Wet Squad. Return to Barla Von promptly, as Barla Von will disappear during the attack on the Citadel, and the Mission will get stuck in your Journal if you complete Priority: Tuchanka before turning it in.
Completing it: Go to Arcturus Stream: Euler System, and Land on Benning. From the landing zone, go right,and enter the building with "52" on the side. To the right next to the sink will be a PDA to Examine. Continuing north through the bathroom and into the bedroom, you will find a bunk bed with a dead civilian. There are some Spare Parts worth Credits on the floor. A civilian will run through the west entrance and be gunned down by Cerberus. Kill the bad guys, then the mission will update and provide you with a second objective.
From Building 52, go just past Building 22. On the ground next to a pillar close to Building 22 will be the Dog Tags belonging to Alliance Soldier Bilal Osoba. These are for the side Mission Benning: Evidence. In the same courtyard, you will find Building 97. Under the painted number "97" is a black and yellow dumpster. To the right of the dumpster on the ground you will find the Capacitor Helmet.
Enter Building 27 nearby. You will find a Medical Station in this building, and Spare Parts for Credits on the bridge between Building 27 and Building 25. At this point you will hear or see Cerberus troops attacking a group of civilians to the south. Clear out the area of hostiles. As you make your way to speak to the civilians, you will be near Building 7 which contains a Computer Console you should read. Left from the middle stairs leading from Building 7 there is a small alley where you will find Spare Parts worth some Credits next to a machine labelled "M382".
Upon talking to the civilians, your goal now is to defend them as they move towards the landing pad for extraction. They're invulnerable, so don't worry about them. Once you've eliminated all Cerberus troops the civilians will head to the landing zone and wait there. On the way back to the landing zone yourself, you will pass Building 5 where you will find a Medical Station. There are also Spare Parts under the counter for some Credits, and a PDA next to the sink. Enter the shuttle to end the mission. A cutscene takes you back to the Normandy. Talk to people to get their reacrions.
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: This can only be completed after Priority: Sur'Kesh. There are some drunk soldiers in Purgatory Bar talking about this, but they don't offer much help. Instead, during the Mission N7: Cerberus Abductions, look for some DogTags in the building with the number 27 on it. If somehow you miss them, you can buy them later in the Spectre Requisitions store. Return to the Ambassador to turn them in.
Completing it: Go to the Krogan DMZ: Aralakh System, and Enter Orbit around Tuchanka. Select the Cerberus Attack Site. Select your team, then enjoy the cutscene. Enemies will already be present at the location when you land. When Shepard says the console has been secured, there will be no more enemies and you're safe to collect all the equipment before Activating the Console.
From where you started, go a little left and through the door. Go past the pile of rubble and in the corner to the left of the crate you will find some Junk to Salvage. Return back to where you started and go right, across the courtyard (where the enemies were coming from), and instead of going up the ramp, go to the right. Approach the ammo and you will file some more Junk to Salvage for Credits.
Climb up the ladder and move around the console to the right. On that side of the first console will be Old Grid Schematics needed for the Citadel: Improved Power Grid Mission. Slightly further along the right wall will be a Med Kit on the ground. Head down the right ramp directly ahead of you out of the control room, and move into the corner on the right (a bit hidden) for more Salvageable Junk. Finally, move around the fallen column and on the other side and pick up the Armax Arsenal Gauntlets.
When you're ready, go back up the ramp, and Activate the Control Console. Cerberus will cut power to the console, so you need to reactivate the power. Kill off all the nearby opponents and move back toward where you started. Shoot the latches off both Power Modules and Reactivate them. Fight past the enemies again and return upstairs across the courtyard. Activate the console to return to the Normandy. (A screen prompt will cause you to focus in on the virtual display, but you can go outside and watch the event live if you prefer.)
WARNING: Must be completed before starting Priority: Tuchanka.
Completing it: During N7: Cerberus Attack, it's right in front of the Cannon Controls. If you somehow miss them, you can later buy them from the Spectre Requisitions store. Return them to Alison.
WARNING: Must be completed before starting Priority: Tuchanka. Can only be completed after Priority: Sur'Kesh, when the system opens up.
Completing it: Go to Ismar Frontier: Aquila System, and Scan Metaponto. Return to the Salarian doctor to turn them in.
Completing it: Go to Horsehead Nebula: Pax System, and Land on Noveria. After the cutscene, take out the enemies in the upper area, then move forward and clear the enemies in the lower area.
Before activating the Control Panel, head around and collect all of the items. From where you started, move forward along the same level and around the corner to the left. Head forward and between the doorway and the ladder you can find Spare Parts to Salvage for Credits. Go through the doorway and down the stairs, and at the bottom go around to the right for the Medical Station against the wall and a Pistol Magazine Upgrade Mod on the chairs. Head around and Examine the Computer Console on the other side of the room. Go down the stairs, turn the corner to the right and Salvage the Spare Parts. Head forward to the Console in front of you to Salvage a DataPad. In this same corner are the Heating Unit Schematics needed for the Mission Citadel: Heating Unit Stabilizers. Access the Medical Station on the wall before going outside. Head to the right and at the back of the catwalk you'll find more Spare Parts to Salvage. Turn around and in the middle of the two catwalks is another Med-Kit. Head to the right and in the far corner by one of the red rectangle marked pillars are some more Spare Parts to Salvage.
Once you have collected all the items, follow the Nav point and Deactivate the Security Console. Pick a squadmate to deactivate the Console. Once the security panel is activated by one of your squadmates, you will have to fight off a wave of Cerberus troops. Once they are dead, you will have to Activate the Console on the left of the display. This is your last opportunity to collect any loot. After the activation you need to clear the landing pad of enemies, including an Atlas. As soon as you kill the Atlas, you will be returned to the Normandy.
CAUTION: Can only be completed after completing Priority: The Citadel II.
Completing it: During N7: Cerberus Fighter Base, they'll be on the opposite wall from the first objective. If you somehow miss them, you can later buy them from the Spectre Requisitions store. Return them to Sellea.
Completing it: Go to Minos Wasteland: Arrae System, and Land on Gellix. The mission begins with a landing on an area that is already under assault by Cerberus forces. If he survived ME2, Jacob Taylor will be injured in the firefight; if not, a stand-in character named Dr. Webber will be hit instead. After you clear the initial pad area, a conversation ensues, followed by three more Assault Troopers before you'll be let in.
Talk to Jacob/Webber to learn about what's happening. On the right, you can Talk to a Grieving Doctor for some Reputation Points. At the top of the first flight of stairs you can find two DataPads. Dr. Gavin Archer may be present, depending on your actions during ME2's Overlord DLC. Through the door is an Assault Rifle Magazine Upgrade Mod and a Weapon Bench. Up the stairs and through another door is a Medical Station. Go up the stairs to start a conversation with Brynn, who will give you your next objective. On the top floor you fan find three DataPads, a Microscope with the poison you need for Citadel: Cerberus Turian Poison, and a Shotgun High Caliber Barrel Mod behind a crate near the door to the next area. You can also Talk to Dr. Brynn and listen to the others for more information.
In the Med Bay you can find the Kassa Fabrications Greaves on some crates by the door, two DataPads, a Medical Station on the wall, and you can Talk to Jacob if he's present. Shepard is tasked with restarting the AA emplacements. To do this, head out through the door and up the ladder. Be sure to grab the M-6 Carnifex heavy pistol on the pipe to the left. When you come around the corner, there are guards facing the wrong way, but they're standing near a Shield Pylon. A large enough explosion will take them all out. Continue up the raised platform to find another Cerberus Engineer guarding the satellite control area.
Reinforcements will jump down to join him. Drop down and pick up the SMG High Caliber Barrel Mod behind the crates on the left. Once you restore the controls, Jacob or Brynn will tell you that the AA guns still need to be activated. Next to the controls you'll find a Med-Kit and a DataPad. Prior to actually activating the Telemetry Override, first climb up onto the next section and destroy all the shield generators and collect all the loot. When you're ready, return to the Override and Activate it.
Cerberus forces drop onto the raised platform you just vacated. Clear them out and ascend. In the distance, by the right AA gun, will be a Turret manned by an unshielded gunner as well as typical Cerberus forces. Before climbing the tower, there is a Med-Kit in the center past the corrugated surface you climb up to in three steps under a curved metal pipe, as well as a Sniper Rifle Piercing Mod that can be found behind the large containers near the ladder to the right tower. This ladder is broken, so make your way up the left tower. Activate the first AA gun and move across the crosswalk to the adjoining platform.
On the second AA tower is a DataPad, and a Med-Kit. Below down the ladder is a Shotgun Spare Thermal Clip Mod. Climb back up and Activate the second AA Gun to discover it requires repairs. Assign the squad member of your choice, then get yourself on the Turret. On the other AA tower and on the platform below, Cerberus shuttles will deploy troops. Once all enemies are dead, return to the repaired AA Gun and Activate it.
The cutscene returns you inside. You have one last chance here to pick up any loot you may have missed. You can also Talk to Jacob/Webber again. When you're ready, Examine the Evacuation Console to order the evacuation. Cerberus troops crash through the sky lights, and you have to fight them. Dispatch the three troops in the upper area and head down to dispatch the three troops on the stairs. When the hangar doors open there are several troops to battle, and as you move forward Cerberus shuttles drop more troops on the raised platforms. Destroy the Atlas and the ending cutscene begins. If Jacob is present, he will be recruited as a War Asset. You can also gain Dr. Gavin Archer as a war asset if you completed the Overlord DLC in ME2 and successfully rescued the Grissom Academy students before this mission. Explore the Normandy to get everyone's reactions.
Completing it: During Arrae: Ex-Cerberus Scientists, there's a Microscope upstars you need to Examine. After the Mission, return to the Doctor.
Completing it: Go to Athena Nebula: Vernio System, and Scan Polissa. Return to the Asari.
Completing it: During Tuchanka: Bomb you'll find them sitting on a crate just before meeting Lieutenant Victus for the first time. If you somehow manage to miss them, they'll be available to buy in the Spectre Requisitions store. After Priority: The Citadel II, return them to the human male C-Sec Officer.
Completing it: First head to the Spectre Office in the Citadel Embassies and read the message about the Batarian Codes. Click Enable while viewing the message. The Citadel Map will be updated with the location of the first console. Find the consoles at the following locations, in this order:
1) Huerta Memorial Hospital - In the room east of the airlock.
2) Normandy Dock: Bay D24 - In the Passenger Lounge.
3) Docks: Holding Area - At the far east end of the map
After retrieving the final code, someone puts a pistol in the Commander's back. There are two paths here, depending on what you did with the Bring Down the Sky DLC in ME1:
1) If Balak survived, you can immediately kill him, or let him live. Killing him causes the Alliance Third Fleet War Asset to have its value decreased. Letting him live adds Balak to your War Assets, and opens up several Mod Upgrades in the Batarian State Arms store.
2) If you killed Balak in ME1, Shepard will meet up with Noles who has a batarian in custody. Choose what to do with him.
Completing it: Talk to them, and a call comes in from someone informing them that he is in position at C-Sec, telling them to distract the security while he moves in to make the kill. Go into C-Sec and Talk to Captain Aaron Sommers. Ask him why he wants to murder the Cerberus agent, then you have some choices of how to finish this:
1) Say You're better than this to admonish Sommers, explaining that he will be dishonouring his Alliance uniform if he guns down the former officer.
2) Say Let me do it legally. Shepard invokes Spectre authority and tells the C-Sec guard stationed there to release the guy to Sommers.
3) Say "Walk away" to warn him that he will get arrested if he attempts to kill the officer.
4) Say "Go ahead" to pretend not to be aware of Captain Aaron's plot.
Completing it: There are four possible locations you need to take pictues of right here in the Docks. Many more false locations are scatered around the area.
1) At the Memorial Wall where a salarian is consoling a grieving human woman.
2) The area between Bay E24 and Bay E26, where a woman is having a conversation with a man.
3) The area between Bay E26 and Bay E28, where James is playing poker with three other players.
4) Cargo Hold: B, where there's a woman and a batarian laying down near refugee camp doctor.
After taking the photos, return to Solik and give him the footage.
Completing it: There are two versions of this, depending on whether or not Conrad Verner is alive.
If Conrad is dead
The Doctor will just ask you to do this. Walk around this area to find 3 Medi-gel Dispensers. There are 4 dispensers around the docks but you only need to fix 3 before returning to the doctor.
1) Just outside Cargo Hold: A on the right.
2) Inside Cargo Hold: A immediately to the left.
3) Cargo Hold: C near the clump of batarians and the kiosk for Batarian State Arms.
4) In Bay E28 in the corner.
Once you have repaired 3 Medi-gel Dispensers, go back to Cargo Hold: B to talk to the Clinic Doctor. He will thank you for your efforts and fret over being unable to track down the saboteur, and the mission will end.
If Conrad is alive
Talking to the Doctor sends you to Conrad, who is in front of Bay E24. You should still fix the Midi-Gel Dispensers bfore talking to Conrad. If you want the Dark Energy Dissertation War Asset, several things will need to have happened during ME1: 1)You completed "Data Recovery" for Gavin Hossle on Noveria, 2) you kept Conrad alive, 3) you completed the Matriarch Writings Assignment, and 4) you purchased the Elkoss Kombine Licence.
During the dialog he'll also apologize for the bug in ME2 where he accused you of pointing a gun at him in ME1, even though you didn't. Compounding the bug, he'll still apologize even if you really did. It is possible to skip this conversation entirely and simply go repair the Medi-Gel Dispensers then return to the Doctor, but you will not receive the War Asset and he will still appear in the next sequence with no prior introductions, and will still act as though you spoke with him. Either way, repair the Medi-Gel Dispensers as above, and then Talk to the Doctor.
This triggers a final scene with Conrad and his Cerberus contact. His contact pulls a gun on Shepard and Conrad dives in slow motion in front the Commander, attempting to intercept the bullet, providing enough distraction for Shepard to clock the contact in the face. If you completed "Citadel: Rita's Sister" Assignment in ME1 by getting Jenna out of Chora's Den, Jenna will have hacked the contact's gun, thus saving Conrad's life, and the two wander off together and live happily ever after. If not, Conrad is shot for real and is killed.
Completing it: Go to the Med Bay on Deck 3 and Talk to Dr. Chakwas/Michel. Go to Docks: Holding Area on the Citadel and head to the refugee medical center in Cargo Hold B. There you will find a turian named Tactus on the right hand side. Talk to him. If you have enough Reputation, you'll be able to swap supplies as your Doctor had suggested. If those speech options aren't available, you can give them away with a Paragon option. (Asking Tactus to reconsider will result in the same conversation again.) Whichever you decide, speak with your Doctor back on the Normandy to complete this mission.
Completing it: First, go to the Citadel Embassies and go to the Spectre Office. Use the Spectre Terminal to receive a location on Din Korlack. Talk to the turian Guard who's outside the Office at the east end of the map. He will let you in. Once you have listened to all three recordings, on the opposite side of the room you will find an ear piece. There will be a cutscene and then you will end up at the Presidium Commons. Head up to either Apartment 80 or 94, the ones at the far ends of the hall. Whichever you try first will be the wrong door. Open the other one to find Korlack. If Zaeed Massani survived ME2, he'll be here. If he was Loyal, he'll be alive, and if not he'll be dying on the floor.
During the cutscene, there will be a choice between saving the colony or gaining the Volus Bombing Fleet as War Assets. If Zaeed is alive and Loyal, you can choose either the Paragon or Renegade option to get both. If Shepard chooses to not warn the colony, the Turian Sixth Fleet will suffer losses during its defense. If Zaeed is Loyal, you will be able to find him in the Docks: Holding Area and recruit him as a War Asset. If he was not, he will be dead.
Completing it: Use the Spectre Terminal to learn where the Batarian is and more about him. Go to Docks: Holding Area, and in the back of Cargo Hold C, there will be a turian nurse standing outside a refugee accommodation. Talk to the nurse, then talk to his batarian patient. The conversation is slightly different depending on whether or not you personally completed the Arrival DLC in ME2. You then have a choice of whether or not to kill him. The nurse doesn't notice either way.
CAUTION: Can only be completed after completing Priority: The Citadel II.
Completing it: After Priority: Tuchanka, go to Aethon Cluster: Aru System, and Scan Irune. Return the artrifact to the Volus.
Completing it: Go to Nimbus Cluster: Mesana System and Land on Lesuss. After you land, if Samara survived ME2, there will be a Shuttle you can Examine on the landing pad. Pick up the Assault Rifle Stability Damper Mod to the left of the door, then go in. The elevator is missing, so you will have to jump across the gap and then slide down into the elevator shaft using the ladder on the right side of the platform. A squadmate will comment on the noises you can hear as you reach the end of this platform and leap across the gap into a disheveled room.
Explore the room to find a Pistol Melee Stunner Mod and some Shadow Broker Intel. On the far left, a Console with an advisory notice from Matriarch Gallae, a PDA on a table, a Sniper Rifle Spare Ammo Mod and a Wall-Safe in a chamber to the right of the entrance door, along with a Console about daily Ardat-Yakshi life at the monastery. A cutscene will play upon examination of the dead asari. Go through the door. There is nothing else of interest in this room, so Bypass the next door and go on to the next room. In this room you will meet Samara, if she survived ME2. After the cutscene, turn right to find a PDA beside another corpse. Pick it up to get the Mission Citadel: Asari Widow.
Head out the door to the left and proceed down the stairs into the courtyard. As you approach the other side of the space, a Banshee will attack you. After you have killed her, several Cannibals will spawn. On the other side of the door, a cutscene will play showing an Ardat-Yakshi, Falere, fighting a Cannibal. Either Shepard or Samara will defeat it, leading to a conversation. Falere will ask you to save her sister. Samara, if present, will chase after Falere. You can Examine the broken elevator on the left side of the room, and there is a Computer down the right side to the left of the working door you can Examine to hear an audio log. Proceed through the working door to find several Reaper troops with their backs to you.
Through the first doorway on your right, you'll find the Disciple shotgun, the Serrice Council Shoulder Guard, and a Medical Station. Go to the room on the other side of the walkway to Access two Computers, loot a Wall Safe, and use the Weapon Bench. If Morinth survived ME2, then one of the Consoles would have a report from Superintendent Jethra to Matriarch Gallae about blocking Morinth's continuous attempts to make contact with her sisters.
Go down the stairs, where you will encounter another Banshee and several Cannibals. After you have defeated the enemies, Bypass the door. In the next room you will find an Assault Rifle Precision Scope Mod up the stairs to the left, and an asari corpse in the middle of the room next to some crates. Examining the corpse will result in a discussion. Activate the elevator to reach the Great Hall. Medical Stations can be found on the left and right sides and a Med-Kit in the center of the room just before the stairs leading up to the Bomb. The Bomb is on the far side of the room. There, Falere begs Rila to wake up, while Samara stands guard if she is present.
Selecting the bomb will cause a cutscene, at the end of which two Banshees and a handful of Husks will attack. After the fight, Examine the Bomb again to watch a cutscene. If Samara is present, at this point she will note that the Justicar Code requires her to slay any Ardat-Yakshi living outside the Monastery. She will commit suicide but can be stopped with a Paragon Interrupt, giving you Samara as a War Asset. Whether Samara is present or not, you will then decide to either let Falere stay on the planet or kill her yourself. Explore the Normandy to get your crew's reactions.
Completing it: Return it to the Asari Widow standing on the stairs between Meridian Place Market and Apollo's Cafe in the Presidium Commons.
Completing it: Go to Nimbus Cluster: Agaiou System, and Scan Carcosa. Return the artifact to the Asari in Purgatory.
Completing it: Go to Valhallan Threshold: Paz System, and Scan Garvug. Return the Artifact to the human in the Docking Bay.
Completing it: After Priority: Geth Dreadnought, go to Argos Rho: Phoenix System and Scan Intai'sei. After gaining the artifact, return to the salarian War Strategist.
Completing it: Go to Silean Nebula: Klypadon System, and Land on Cyone. As you enter the facility, the Turan Nyrek will greet you. Walk to the left area to pick up the Rosenkov Materials Chestplate. Walk further up to pick up a DataPad containing the Medical Treatment Plan for the Mission Citadel: Chemical Treatment. After that, head towards the right side of the facility to Talk to Captain Lee Riley. A container behind her will be moved to reveal a corridor. Do not attempt to go near the left edge, as the area below is filled with toxic gas. On your right, you will come across a Crane Display Terminal but before activating it, go past it and Salvage the Spare Parts for Credits.
Activate the Crane and a display will appear. The display shows a live video feed which is recording from behind you. You will need to use the 3 buttons to move 2 containers, from left of the screen to the right. Move both the crates from the left to the right. Once the path is cleared, Riley will then get into position, sending you to go find a way to vent the area. From the Crane Display, follow the path all the way around to your right. There will be a Control Console to vent the toxic gas. After Activating it, head to the area that just opened up. You can find a PDA next to the Fuel Rod Control for Credits, and a Med-Kit in the same area far back by the yellow vehicle.
When you're ready, Unlock the Fuel Rods. Reaper forces will attack. After you have cleared the area, you will need to seal the two Moderator Tanks. Just follow the Nav Points and Reactivate each tank. Follow the next Nav Point and loot the DataPad with Credits, then Activate the Restart Reactor switch. After you so do, more enemies will attack.
Once the area is clear, Riley will talk to you over comm and say how they are not going to make it. She's right. You can choose to ask her to keep at it by herself (in which case she'll die), or help by sending one of your squadmates to ensure her survival (she's worth War Assets). Now the central chamber doors will be opened, only to reveal some enemies. Once you dispatch the enemies, Initiate the Final Startup on the nearby console. There are no more enemies to kill, so go straight back to the extraction point. If you chose to send some help to Captain Riley, she'll be here and you can Talk to her before you return to the Normandy. Otherwise Nyrek will be the sole survivor. If Riley survived, there will be an option on the Spectre Terminal at the Citadel to grant her a commendation and gain her as a War Asset.
Completing it: After Priority: Geth Dreadnought, during the Mission N7: Fuel Reactors, go left from the starting area, and you'll find the information you need on a DataPad. If somehow you manage to miss it, it can later be purchased from the Spectre Requisitions store. Return the info to the Doctors in the Huerta Memorial Hospital.
WARNING: Must be completed before starting Priority: Rannoch.
Completing it: Proceed along the only path you can until you come to a crashed quarian escape pod. Some Geth will be standing with their backs to you. Wipe them out, then up on the path to the right is some Salvage labeled Geth Parts. Examine the dead quarian and Salvage some more Geth Parts next to the burning debris. Proceed along the trail and be careful of the trip mines on the ground. Pick up the Javelin sniper rifle on the ground and continue.
You will be moving on an outcropping that overlooks a Geth patrol. Eliminate the hostiles and move down to the second crash site where more Geth will drop in. Kill them and move forward, watching for more trip mines. The path leads to the AA Tower where you will be met with oblivious hostiles. The moment you begin your attack, several more enemies will drop from the sky. Once you eliminate them, Salvage some Geth Technology left of the AA Gun Control. Go to the right near the controls and pick up a Geth Spitfire heavy weapon. Now Examine the AA Gun Control and choose one of your squad members to take the AA guns offline. You must defend the position from a group of Geth. Once the hostiles have been eliminated, your squad member will notify you that the AA Guns are offline and a second wave of Geth will attack your position.
Eliminate all hostiles and proceed up the hill, being sure to pick up the Assault Rifle Magazine Upgrade Mod and a Med-Kit on the left. Climb over a bridge and watch out for a proximity mine. You will come to a clearing with several disabled geth. Pick up a Shotgun Shredder Mod to the left and Salvage the Geth Parts. Talk to Dorn'Hazt. He directs Shepard toward Koris' location. Continue along the path to the Tower, picking up the SMG Magazine Upgrade Mod on the way. You can choose to either go left or right at a fork, but I'll explain the right side first.
Move along the path to the right and you will encounter several Geth and a mountable Turret. Eliminate all hostiles and move up to examine the AA Gun Control. Nearby the AA Gun Control is the Armax Arsenal Chestplate. Choose a squadmate to disable the gun. Double back to the Turret and use it against incoming enemies. Once all hostiles have been eliminated, a door to the right of the Turret leads to the other AA Gun. More hostiles will be waiting inside the hallway and around the AA Gun. Eliminate them and before proceeding to the AA Gun Control, head to the left from the hallway exit and at the first highlighted Terminal, retrieve the Jamming Tower Data for the Mission Citadel: Target Jamming Technology.
Examine the AA Gun Control. Choose a squadmate to disable the Gun, and move to the Turret. Defend the area from a large number of Geth. Once all hostiles have been eliminated, your squad mate will notify you that the gun is offline. Shepard will then board a shuttle and contact Admiral Koris, who is engaged in a heavy firefight. He refuses to be saved, preferring that you rescue his crew. With sufficient Reputation, however, he can be persuaded with either the Paragon or Renegade options to be picked up instead of sacrificing himself. If Admiral Koris dies, the Quarian Civilian Fleet War Asset will be reduced by 75 points. Also, it may not be possible to make peace between the Quarians and Geth at the end of Priority: Rannoch. If Admiral Koris survives, he is added as a War Asset worth 25 points, and counts as a "point" towards making peace between the geth and quarians.
Whatever your choice, you will mount a turret inside the shuttle and provide cover fire for whoever you are rescuing. Once your chosen party makes it to the shuttle safely, you all return to the Normandy, where you should explore the ship again and talk to people. Some more parts of the Galaxy may be open to explore now as well.
Completing it: During Rannoch: Admiral Koris, look for the Jamming Tower Data at the Terminal diagonally opposite the last AA Gun Control. If for some reason you miss it, you can later buy it from the Spectre Requisitions store. Return it to the turian C-Sec Officer.
WARNING: Must be completed before starting Priority: Rannoch.
Completing it: Although you are asked to select squadmates for this mission, they do not really participate in the mission, they only talk during cutscenes. After the cutscene, you enter the Geth's virtual world. This Mission is very straight forward. There are no enemies that attack you here. Just continue to follow the floorplates as they fly in and land in front of you. Destroy the obstructions and open the Nodes. Follow your guide's instructions when new wrinkles appear. Be sure to View the historical footage after you destroy a Node, as they contain Intel.
There is only one thing you might miss. After passing through the first Access Point, look on the left side of the path near the first Node for the orange brackets along an indestructable tendril to get the Reaper Code Fragments which are required for the Mission Citadel: Reaper Code Fragments. After your return to the Normandy, remember to talk to everyone.
Completing it: During Rannoch: Geth Fighter Squadrons, it is found near the first infected data cluster you encounter. If for some reason you miss it, you can later buy it from the Spectre Requisitions store. After collecting the code, return to the Asari War Strategist and give it to her.
Completing it: Go to Silean Nebula: Phontes System, and Scan Dekuuna. If you've already been there to get the artifact for Dekuuna: Code of the Ancients, you may already have rescued these elcor. In that case, go to some other floor of the Citadel and return immediately. Talk to the Elcor Diplomat again to get your reward.
Completing it: After Priority: Rannoch, go to Silean Nebula: Phontes System, and Scan Dekuuna. Return the artifact to the elcor.
Completing it: After Priority: Rannoch, go to Hades Nexus: Hoplos System, and Scan Kopis. Return it to the seated human male.
Completing it: After Priority: Rannoch, go to Hades Nexus: Sheol System, and Scan Gei Hinnom. Return the artifact to the refugee.
Completing it: After Priority: Rannoch, go to Silean Nebula: Teyolia System, and Scan Nevos. Return the Artifact to the Asari in the Hospital.
Completing it: Go to Kepler Verge: Newton System, and Land on Ontarom. Wipe out the initial Cerberus troops, then take your time and look around the map. You have unlimited time before you must activate the NavPoint console, so get all the loot before the next fight. From your starting location, drop down into the courtyard. Head left, then take another left up the ramp to find a Med-Kit. On your left is the Console with the Codes needed for Citadel: Cerberus Ciphers. In the opposite direction is a box labeled Cerberus Technology, which you can Salvage for Credits. Behind this pillar towards the outer edge is another Med-Kit.
Head up the ramp near the outer wall, where you'll find more Cerberus Technology to Salvage for Credits. Head forward, but just before the up ramp, turn right and drop down the ladder leading to the underside of the satellite dish. In front of you will be the Ariake Technology Geaves. Go around the other side of the central pillar for some more Cerberus Technology worth Credits.
Continue forward toward the left-side ramp. Before going up the ramp, turn right to pick up another Med-Kit. Go up the ramp, turn left and go up the second ramp. Turn left again to get into a circular room. There's a Medical Station on the wall next to the right-side door.
Once you've got all the loot, go ahead and Deactivate the Console. After this, a second Nav Point appears, along with more Cerberus troops. After they're dead and the second device is disabled, a cutscene and dialogue with Ms. Sato occurs where you receive the info on the third Nav Point. Clear out the enemies and be sure to grab any loot you've missed, as once you deactivate the third station, the mission will immediately end. Talk to your crew to advance their conversations.
Completing it: During the Mission N7: Communication Hub, after the 2nd objective, the Terminal you need is on the far right. If you somehow manage to miss them, they become available to buy at the Spectre Requisitions store.
Note 2: It's possible for Aria to kiss you at the end of this DLC. This is only possible if you do exactly as she says, and agree with her every step of the way.
BUG: There are three side quests in here. If you don't complete them, they will get stuck in your log for the rest of the game.
Dock with the Citadel or Use the Citadel Rapid Transit, and choose Dock 42. You'll enter into a conversation with Aria. After this, you'll be returned to the Normandy. Leave the Citadel, and Dock with Aria's Fleet, which is in the same system.
After the lengthy cutscenes, you gain control of Shepard with the immediate task of killing the nearby Cerberus troops. Aria is a squadmate, so be sure to allocate Talent Points to her. When the area is clear, loot the two Med-Kits, then Use the Blast Door Controls, and go through the door. Once you clear out the next room, there are some Tools which you can Salvage for Credits and an Assault Rifle High-Velocity Barrel Mod. Open the door on the right to enter an elevator.
Go to the left and Use a Computer Terminal before going through the door. Next, you'll enter a ventilation room, filled with more Cerberus troops. Once cleared, Aria will move ahead on her own. Loot the Medical Station next to her, then Talk to her. Aria will call to Shepard’s attention that the room ahead needs to be pressurized. While you wait, you'll have to hold off another wave of Cerberus soldiers who enter the room from behind you.
After walking down a hallway, Bypass the door which leads to the control room. Once it's open, find a Med-Kit straight ahead, then you'll have to kill some more Cerberus goons. When you Use the Defensive System Controls, a short cutscene will play out, during which you'll have a Renegade Interrupt Opportunity, should you wish to shoot the camera spying on you. If you don't take the shot, Aria will. Before leaving the control room, you can find on the left wall a Medical Station. Before entering the elevator, look up at the screen to see some examples of Cerberus brutality.
Moving on, you will be shot at immediately after the doors open. Clear out the area, then Salvage a Wall Safe on the left. Go through the security barrier and Use the Garage Door Controls to open them. Admire the Omega skyline, Salvage some Tools straight ahead for some Credits, and pick up the Pistol Heavy Barrel Mod next to that, then go past the Control Screen and hop over the crate into another fight. When the area is clear find a Med-Kit on the left, then get on the next elevator.
Exit the elevator into a hallway where you can Examine a crate marked with Talon graffiti. Nearby, you can Salvage some Scrap Metal for Credits. Move ahead and turn to the right, then jump down to see a cutscene. Kill the mechs. Once the area is clear, there is a Med-Kit at the far end of the hall near the force field before you meet up with Aria. Follow her and Use the Door Controls. Hop over the barrier, loot the Medical Station, pick up the Shotgun High-Velocity Barrel Mod, and go down the ladder to meet Nyreen Kandros, a female Turian.
You should allocate her Talent Points before moving on. Find some Scrap Metal to Salvage for Credits and a DataPad, as well as the N7 Valkyrie assault rifle. Bypass the door ahead to continue. There is a Weapons Bench against the wall to your right, which you may want to use to make use of the gear you've picked up so far. Move ahead down the tunnel, and then take the ladder to the upper level. Loot the nearby Medical Station, that is obscured by the fire. Jump onto the balcony below. There will be a large amount of Cerberus troops, including an Atlas, on the balcony in front of you. There are a Medical Station and a Med-Kit on the left, and another Med-Kit on the right.
Your next target is a Cerberus Engineer who is jamming the Cannon Controls. Concentrate on the other troops before you take him out, because as soon as you do, another Atlas will deploy in front of the Cannon Controls. Be sure to get all the loot from the area, as once you Activate the Cannon Controls, a cutscene will follow, at the end of which you'll find yourself in Aria's Bunker.
After the cutscene, head down the corridor and Examine the crates for a comment from Aria. Head right, across the gap, and up a ladder to find a DataPad with Credits to the left before the stairs. On the right, after the stairs you will find the first Hacker Terminal (don't miss this!) and a Lift Control. The Lift is jammed until you shoot the Explosive Crates on it. Head back down to the now functional Lift and Use it to get the Assault Rifle High-Velocity Barrel Mod, then climb over the crates to get into the air vent.
A DataPad with Credits on it can be found straight ahead soon. Use the Air Seal and Terminal to learn that they won't work without power. A DataPad is to the right of the Terminal. Reactivate the Generator to operate the Terminal, then open the Air Seal to continue. After you go down the ladder outside the vents, on the left behind some crates, Examine some Salvage for Credits. At the bottom of the stairs to the right, you'll find more Credits to Salvage. Open the door and head down the stairs into a fight with Cerberus troops.
When the area is clear, the second Hacker Terminal (don't miss this!) is in the right corner of the room, as you face the windows with Omega's skyline. A small room with a broken window opposite there contains a DataPad with Credits on it, and you'll find a Medical Station before the next door. Through that, a Cerberus Trooper will be standing with his back to you when you open the door, and an Engineer waits in the adjacent room. Take them out and you'll find a Medical Station on the left wall, and a DataPad with Credits around the corner in the small room to the right. Deactivate the Cerberus Lockdown in this room.
Releasing the lockdown opens the elevator door on the far side of the hallway, letting out some enemies. Revive the Injured Talon in the next small room on the right for some XP, then Activate the third and final Hacker Terminal (don't miss this!) behind him. Enter the elevator once you're done. As you head down the next hallway, enemies will run in from the landing pad. When the area is clear, there's a Medical Station on the left wall of the area before the landing pad. When you get up there, you'll see another landing pad to the left. Kill the Cerberus troops who arrive on a shuttle, then find a Med-Kit where they landed. Two more Injured Talons are to either side of the destroyed shuttle nearby. It's hard to see the interaction brackets until you're right on top of them, but they look identical to the first one you healed. Revive them for more XP, then head down the stairs and Bypass the door.
In the next cutscene, you join up with Nyreen again. Regardless of what you say to her, she'll be rejoin you and Aria. After you regain control, you'll be facing the exit, but behind you there's a Shotgun High-Velocity Barrel Mod, and a DataPad with Credits behind some crates. Next to the door are the Phaeston assault rifle and a Medical Station. You may also want to allocate Talent Points for Nyreen. Go through the doors and take the elevator up.
As you enter the open area ahead, you'll have Cerberus troops to kill. You can find two Hydra Missile Launcher heavy weapons in the center of the area, one near the left barrier and the other on the stack of crates towards the right. Use both as you see fit, or save one for later. Afterwards, Examine some Salvage for Credits on the right side of the room just before a jumpable gap, and a Med-Kit on the right in the open area under the burning shuttle. One more Med-Kit is on the left near the entry point close to the burning fire. Head through the far doors to the elevator.
When your ride is suddenly cut short, shoot the latch off to open Emergency Access, which drops a ladder into the elevator. Grab the DataPad with Credits off the catwalk behind you, then get on the catwalk and go down two ladders in the elevator shaft until you reach a door. There will be a Med-Kit on your right as you exit onto some more catwalks. There's also some Salvage in front of the burning gap in the catwalks. A shuttle will drop off Cerberus troops behind a smokescreen on the catwalks.
There's a Sniper Rifle Thermal Scope Mod on the right-side of the catwalk. Pick it up then Examine the Door at the end. While the bypass is in progress, endless waves of enemies drop down to the catwalks from a bridge above. The tide of Cerberus troops ends when the bridge above extends, cutting them off. The door won't open, however, until you've killed the remaining Cerberus troops who've dropped down to your level. Head in through the door, grab the Med-Kit, then take the elevator to enter the Talon Outpost.
After the fight, there are two more Talons you can Revive for more XP: one against the wall opposite where you entered, and the other behind some crates left from where you entered. Your last fight at the Talon outpost will be back at the main gates. There are two Med-Kits close to the right wall near the entrance. Make sure to grab them before you take out the rest of the Cerberus forces, as you'll get a cutscene when the area is clear. There's also a turret on the left side if you'd like a bit more firepower.
The place is dark at first, but will be lit soon, so don't worry about missing any loot. Just follow the trail of dead Cerberus Troopers. Eventually you'll come to an elevator, and Aria mentions you need to get power to it. Follow her to the right and up a ladder, then follow her again by hopping down onto some pipes. You'll need to take the lead again by hopping over a couple of gaps. When you get back on a normal catwalk, go past the entryway, and around the corner you'll find some Credits to Salvage.
Go through the entryway and down the next ladder. Inside this small room, Reactivate the Power Module to bring the lights on. This causes an Adjutant to attack you. Kill it, then find a door to Bypass and exit. You'll be back in the area before the elevator. Follow the catwalks and make your way back to the elevator. You'll encounter four more Adjutants. When the area is clear, find some Credits to Salvage up the stairs to the left as you face the elevator. When you're ready, Use the Elevator Control and get on it.
When you leave the elevator, follow the catwalk until you get to a branch. Go in the area to the right marked "EEZO ANALYSIS TESTING" to pick up an Assault Rifle High-Velocity Barrel Mod. A bunch of Cerberus troops will then attack you. Make your way forward until Aria mentions an elevator you can use. The bridge to it will explode as you get near, and a pair of Nemesi will attack from across the way. When they're dead, go down the nearby ladder, only to be attacked by several more Cerberus troops on both levels.
When the area is clear, go straight ahead and open the door to the "MAINTENANCE AREA." Pick up the Pistol Heavy Barrel Mod, then go down the ladder. Nearby you'll find a Medical Station. Loot it, then kill the Cerberus forces at then other end of the corridor. Go through the door at the end and up the ladder.
Once you're clear of the ladder, Aria says "head up", but there's loot to be found on this level. Go around the corner to the left, to the "TRIAGE AREA". Salvage the Tools, pick up a Sniper Rifle Thermal Scope Mod, and Examine a DataPad. Head up the nearby ladder, (which leads to the same location as the stairs) then take out more Cerberus troops here. Just follow the Nav Point from here and get on the elevator.
Upon exiting the elevator, go through the door to the right, and you'll see a Cerberus Engineer standing with his back to you. Eliminate him any way you want, then turn to your right and pick up the Shotgun Omni-Blade Mod and the Chakram Launcher assault rifle. There's only one way forward, through the door marked "PEDWAY ACCESS." In the room is a Medical Station to the left, a dead trooper crushed between doors from whom you can Salvage some Credits, some Salvageable Tools, and a ladder down, which you should take. Head across the unstable catwalks to the final elevator.
On the catwalks near the reactor you can Salvage some Equipment for Credits on boxes just to the left of the reactor. As you approach the reactor, a force field traps you. A short cutscene takes Aria out of the fight. You and Nyreen have to protect her by holding off waves of Rampart Mechs. Either position yourself next to Nyreen and pick a direction to shoot, or just run in one direction around the circle, killing as you go. When the mechs are dead, a cutscene shows that you'll have to make your way to the reactor alone.
A Med-Kit is found to your left up the stairs. Fight off several enemies as you head around to the reactor controls. Or, just run past them all and up the stairs, then in the door. Once you're there, you're presented with a choice:
1) Use one of several Renegade Interrupt Opportunities to override the power, shutting down the fields immediately, but sacrificing life support for thousands on Omega (If you're going for the kiss, you must use the first iterrupt).
OR
2) Ignore the interrupts, and you'll eventually reroute reactor power to just take down the force fields. However, if Shepard is an Engineer Class, you can also use a Paragon Interrupt to reroute reactor power quickly.
Early in the next scene, you have a Paragon Interrupt Opportunity if you'd like to defend Nyreen against Aria's verbal abuse.
Take out the Cerberus troops, then Open the green door and Examine some Equipment for some Credits. Then Bypass the other door to continue. Slide down a ramp, Deactivate the Spinning Fan, then jump the gap to stop the Combat Engineer and Troopers messing with the support columns. There are Med-Kits on each of the four platforms (two raised, two with giant fans) that line the walls around the perimeter of the room. Activate the Access Panel Controls and all four bombs go live just as Cerberus forces drop in. You have five minutes to disable the bombs. Endless Cerberus troops arrive, so just run around the room disabling bombs before killing them. You may, however, have to kill a few to get from Bomb to Bomb.
Examine the Video Log. Head to the right to find DataPad with some Credits. Continue through the door on the other side of the Video Log. A DataPad is on your right, just before the next door. Open the final door to Gozu district, and fight off the Cerberus troops and Atlas. There's a Med-Kit at the bottom of the ladder on the left side of the room from the entrance and a second one on the other side. Head up one of the ladders to open a door for some Salvageable Equipment. Bypass the door on the ground floor and head up a ladder to enter the slums.
Head to the left for a DataPad with some Credits, then return to the right. A Pistol Heavy Barrel Mod is straight ahead through the doorway, down a short drop. Head through the next doorway. Examine a dead Cerberus trooper for some Credits, then go through the door to kill off more enemies. Note that there is a shield generator on the other side of some crates that you don't have line of sight on, but stupidly, the generator attached to it is on your side. There's a Med-Kit to the right before the stairs. Head up some stairs and Bypass the door to enter Talon-held territory.
Salvage some Junk for some Credits on the boxes near a Turian Civilian you can Talk to, then head through the door on your left to Talk to an Asari Civilian, Examine some Lab Equipment for Credits, and use a Work Bench if you like. Head down the hall past the Mad Batarian Preacher, and pick up a Shotgun Omni-Blade Mod at the armed barricade. Take the elevator. After the cutscenes, turn around for a DataPad with Credits, and then catch up with Aria to face off with Petrovsky in Afterlife.
Your goal is to save Aria, and you'll see her life meter slowly run out in the upper right corner of the screen. There are four Generators spaced around Aria's cage. You need to destroy them, but you'll have to first Activate each corresponding Generator Control, which are located in the corners of the room. Enemies will spawn endlessly, so the best bet is to kill as few as possible as you run between Controls. You'll also want to shoot the Generators from the upper level, so as to prevent the enemies becoming nigh invulnerable. You'll find a Med-Kit along each of the two longer outer walls.
Once Aria is free, when you're ready, Bypass the door to face Petrovsky in his den. Depending on the overall morality of your actions during this mission, Aria will either kill (Renegade) or spare (Paragon) General Petrovsky. (If you want the kiss, just let Aria kill him.) If Aria is unwilling to spare Petrovsky, you can use two Paragon Interrupts to force her to spare Petrovsky, though doing so will make her mad at you. If Aria delivers Petrovsky to you, you can use two Renegade Interrupts to kill the general yourself. You will then have the Omega Raiding Fleet and Omega Eezo Hoard War Assets. Sparing Petrovsky will earn you a third War Asset worth 30 points, and killing him will add 30 points to the Alliance First Fleet. Upon returning to the Normandy, you'll receive an email from Aria informing you she's had Petrovsky's chess set sent to your cabin. It'll be there, but you can't interact with it.
A complete search of the lab and the upstairs bedroom will turn up six different Filters. Only one Filter needs to be selected for Shepard to be able to leave the lab and explore possible Leviathan sites around the Galaxy, but you can opt to use additional filters to tighten the search. Using the Creature Sightings, Locations with Element Zero, and Reaper Activities Filters simultaneously will pinpoint the correct location. Using the three correct filters at once, without the incorrect filters, will get you the Conspiracy Theorist Accomplishment.
Before you leave, pick up all the loot. The Pistol Cranial Trauma System Mod is in the far left corner of the balcony; the SMG High-Velocity Barrel Mod is across from the Citadel Rapid Transit; the Pistol Ultralight Materials Mod is next to a tree on the right side of the balcony; while the SMG Mass Pulse Recoil System Mod is on a shelf near the Rachni Information. Before you head to the next destination, note that several systems will have opened up for exploration and exploitation. These are the places you would have visited, had you not found Garneau's exact location.
After regaining control of Shepard, you'll be able to look around, overhear some of the other personnel talking with each other, and find that you now have to repair the elevator. There is a DataPad near the group in front of the customs personnel you can interact with to get some Credits. There is another DataPad behind the reception desk that also yields Credits. The men behind the reception desk will bark at you but won't bite. At the side of the room opposite from the door you entered from, you'll find a Repair Drone Terminal you can use to activate a drone to fix the elevator. Stay near it to guide it to the elevator. After fixing the elevator, ride it up to the next floor.
Inside this hallway, you can find a DataPad behind a crate of rocks to the left. Then move through either door, as both lead to different parts of connected rooms. There are various objects you can interact with that show that T-GES Mineral Works is not what it seems. In the room with the potted plants are a Terminal and a DataPad, both with Credits. Check out the Security Terminal with the floor map: you need a password for further clearance. Now head to the next room. Behind the 3D display console there's a DataPad with Credits on it. Bypass the next door. Inside the room is an SMG High-Velocity Barrel Mod and a DataPad with Credits and the Password you're looking for. You need one more piece of information.
Go through the upper door labeled Sector 4, then go in the small room to the right. Look at the DataPad to get a Personnel ID. Now head all the way back to the Crew Quarters and use the ID you just found to get in. There is an Ultralight Pistol Materials Mod and two DataPads inside. Return to the Security Terminal and Access it to open up the Medical Bay, which is just past where you found the Personnel ID.
Once inside, there's a Med-Kit next to a windowed room with a corpse on the table. Examine the Body to meet Dr. Garneau. After a conversation, give chase. After the second door, take the ladder nearby to get outside. Once out, follow the linear path towards the Nav Point, and kill the Husks that are chasing after your target. In the next open area find an SMG Mass Pulse Recoil System Mod. Further along, you'll find a Reaper Blackstar, but you'll want to save it for when the Banshees appear. Once the area is clear, search the area to the right of the door for a Med-Kit and a Pistol Cranial Trauma System Mod.
As you Access the door, power goes offline and now you have to escort another repair drone to repair two power units in the open area you just came from. Enemies appear in infinite waves, so stay close to the drone and keep it moving, otherwise it'll run out of power and you'll fail the mission. Beware the Banshee towards the end of the fight. When the power is restored and the area is clear again, Open the door and go into the mine for a cutscene. Back aboard the Normandy, some of your crew will comment on the Mission.
After you exit the structure you come to a dead end. Turn around and climb up the ladder. Kill the Husk waiting for you, then find a place to jump across to the rocky area. The Bridge Control Panel there needs to be fixed, and one of your squadmates will volunteer themselves to do so while you fight off some Husks. After the Husks are defeated, the squad member will have finished with the controls just in time for the arrival of a Banshee. Take care of her, then move on. You'll encounter a few more Husks on your way to the elevator.
BUG: A common glitch in this area prevents you from going down a ladder. Depending on your system, either looking up when approaching the ladder or using the walk-not-run key will get you through. Reloading an earlier save also seems to work.
When you Activate the Elevator Controls, the car comes down part of the way but is blocked because of damage to the elevator shaft. Shepard contacts Ann for a workaround--she activates a door one level up and gives a new Nav Point. Go into the building next to the elevator to find an SMG Mass Pulse Recoil System Mod on a counter. Keep moving up and around the wreckage. You'll encounter more Reaper troops. In the building on the right is a DataPad with some Credits on it.
After taking care of more enemies, climb up the ladder and you'll find a Med-Kit in the building. Move out onto the balcony. At the end of it, Shepard will comment about the way being blocked: simply turn around and climb up the ladder, then navigate over the debris. Keep moving forward and dispose of the occasional enemies that try to stop you. Eventually you'll be able to climb onto a structure and move to the rock wall to which the buildings are attached. There are a few more enemies that attack soon after you do so.
Move forward and a platform will collapse in front of you. Move back to the structures and keep going. You'll encounter more Reaper troops. Do enough damage to the Harvester, and it will fly off. After the area is clear, pick up the Med-Kit on the path by the corner of the building. Kill the enemies in the next area. Along the wall between the first entrance and the one where the Ravager was located is an Assault Rifle Omni-Blade Mod. Near the exit there is also some Damaged Machinery to Salvage for Credits.
Move forward and a squadmate will yell about the elevator. Before getting on it, find a Med-Kit and Salvageable Data inside the building just before the elevator controls. Now Activate the elevator and you'll get a cutscene. Afterwards, it's time to kill more Reaper troops, including a Harvester. The Harvester needs to die in order for Cortez to get the shuttle in to land. Once it's dead, you can ignore the rest of the enemies just head to the shuttle. On the way there is a Med-Kit on a desk to the left. In the building past the shuttle, there is another Med-Kit and Salvageable Data. A cutscene plays out for you. Back aboard the Normandy, your squad mates will comment on the Mission.
As you get towards the far end of the platform, Reaper foot soldiers start pouring in. As you finish them off, Cortez will get the shuttle in the air again, but only briefly, and he lands the shuttle at the other side of the wreck. There is Mining Equipment to Salvage just past the part where you have to leap across. Deal with the Reapers here, then you'll find an Ultralight Pistol Materials Mod in another nook by the ocean, near the tarp nearest to Cortez. Note the locations of the M-560 Hydra by the supply stashes behind Cortez, along with the Med-Kits. When you're ready, Talk to Cortez.
Your next task is to open the door to the nearby Triton. To do this, you need to insert the Power Cells Cortez gives you into nearby Power Sockets. One of the sockets is near the bay door itself, and another is at the seaward side of the wreck. When you insert a Cell, the power will slowly leak out, as shown by the meter in the upper left part of the screen. I advise positioning your squadmates to cover you, then just running back and forth between Cortez and the Socket nearest the Triton. As the power gets close to full, use the M-560 Hydra when the Brutes appear.
Once you get the door open, get in the Triton to clear out the remaining enemies. You actually do have to use the Triton, as enemies will spawn infinitely if you don't. It's exactly like an Atlas, if you've ever used one before. When the area is clear, walk the Triton over to Cortez. You then get your last chance to scour the area for loot. In the area where you picked up the Triton, you'll find some Xenotechnology to Salvage. When you're ready, Talk to Cortez to start the next cutscene.
Your goal is to find the Probe you used to Scan the planet before you Landed. Just follow the flares that the Triton automatically spits out for you. Meet the Leviathan. After a long conversation and several cutscenes, you'll be back aboard the Normandy, with the new Leviathan Enthrallment Team War Asset. If Ann Bryson wasn't incapacitated earlier, she also becomes a War Asset. Explore the ship to get everyone's reactions.
Completing it: For the single-player campaign, contains new missions, new temporary squadmates, new places to explore on the Citadel, new weapons, new weapon mods, new armor, new War Assets, and a new "collectable" item. I recommend waiting to do this until just before Priority: Cerberus Headquarters, because some characters won't join your Party until after they've completed their part in the game. For example, Miranda won't join unless you've helped her complete Priority: Horizon. If you're looking for justification for putting the Normandy in dry dock, EDI does mention at one point that the Normandy will need it "before the year is out." Also, your old apartment from ME1 is probably under Reaper control.
When you're ready, exit the Apartment and use the elevator at the end of the hall. A cutscene will show your arrival at the Sushi Bar. Head into the back corner of the restaurant, chatting with the host and bartender briefly, then Talk to Joker. After some small talk, you'll meet Staff Analyst Maya Brooks of Alliance Intelligence. Some more serious conversation starts, then several mercenaries in armor stroll into the bar. Now you get control of Shepard, with the M-11 Suppressor heavy pistol as your only weapon. Kill the mercs. Two headshots should do it, but you have limited ammo, so use your Powers primarily. Once the initial set of mercs is dead, more will arrive on the stairs in sets of two. Ignore them and just run to Brooks near the entrance and Revive her to end the fight.
A short cutscene will play. Proceed out the door and jump across to the next platform, down the ladder to your left, and then across to the next platform. There you will find a DataPad about new temperature units. Head down the next ladder and Shepard will notice a landing pad across the way. (You may also notice a volus going inside). Head down the next ladder and into the building behind you. Head across the room, up the ladder, turn left, then across the gaps. Once you reach the end, there is a group of three enemies down on the lower level. Once you are clear, continue down the marketplace and you will find another DataPad near some Thermal Clips.
When you finally get to the end of the marketplace, you will encounter more enemies. Behind the cover at the end is a Pistol Power Magnifier Mod and a Terminal with Credits on it. Head back out and around to the left. At the end is another stack of Credits and another DataPad. At the end is a bridge, locked down of course, but you can Bypass it. Before doing so, there is a room to your left with a Terminal with more Credits. Once you start the Bypass, an alarm is triggered and more mercs pour in.
Once you have cleared the way, advance, and along the right side will be a series of stores with Terminals, DataPads and an Assault Rifle Ultralight Materials Mod. When the path narrows, be warned there are more enemies coming. Once you have finished, head down and to the right to find another Terminal with Credits. Head inside the door, and you will find a squadmate who will team up with you. In the car store, you can investigate each car to read a sales pitch for it. Find the Control Panel to unlock the landing pad door. There is a Sniper Rifle Ultralight Materials Mod near the door which you entered from, so don't miss it. There is a Terminal with Credits near a door at the back of the showroom.
As you approach the door to open it, it is suddenly locked by the volus you may have noticed earlier. Your squadmate opens it for you. Head out the doors and the C-Sec shuttle arrives, but it is yet another ambush by the mercenaries who open fire on you. Wrex or James will then arrive and join your squad. Don't forget to allocate Talent Points, especially to Wrex. The enemies are infinite in number, so just survive until you hear Joker tell you to get to the shuttle. The extraction zone is next to where the mercenary shuttle arrived at the start of the fight.
Once you find Brooks, she mentions there is an alarm on the grate. Follow the blue wiring, as instructed. The junction box is at the other end of the upper level guarded by a camera. Stay out of the yellow cone of sight that the camera puts out and hack the camera from the side. The yellow cone will turn green for a few seconds, allowing you to stand in it to hack the alarm. If it turns back to yellow while you're standing in it, the box in the lower right of the screen will say "Suspected." Mingle once to reset it and try again. Succeeding advances Brooks. After Mingling a bit more, Brooks runs into another problem: there is a guard right beneath her. Follow the Nav Point and Talk to him. Brooks will radio she is clear, so back to Mingling. Be careful to avoid setting things off. There are two ATMs on the ground floor you can get at for Credits, but you have to bypass the respective cameras to do so, and it is a Renegade action.
When Brooks contacts you again, she has run into two problems. Follow the red wiring. On the left is the Pressure Pad. You have to distract a guard and a camera simultaneously. Send your squadmate to distract the guard, hack the Camera, then the Security Device. On the other side, send your squadmate to distract the stationary guard, and watch the patrolling one for the right moment. Be careful when you try and go, because if you get seen, you become suspected. Mingle immediately or it will be game over.
After bypassing them both, you'll need to distract another guard. Again follow the Nav Point to find him. Mingle some more. Brooks will finally radio she is in and now you needs to meet her. Follow the yellow wiring this time. This is the hardest part, but thankfully the last. First, stand next to the camera to the right, next to the human guests. When the patrolling guard is nearest to you, just as he turns around, order your squadmate to distract the stationary guard, then immediately hack the camera next to you. As soon as that's done, run to the other camera, and wait for the patrolling guard to turn around before you hack it. Quickly run to the third camera and hack that. This will trigger a cutscene.
Before leaving, grab the Shotgun Ultralight Materials Mod and the Med-Kit on the right. At the top of the ramp behind the door is a Terminal with Credits on it. Beyond the scanners is another Med-Kit and an SMG Power Magnifier Mod. Enter the next room. At the other end of the catwalks, CAT6 soldiers descend. Kill them, then step onto the platform, which will move you to the next area. When the platform stops, there is an M-7 Lancer assault rifle on a bench to the right. This rifle does not use clips, but rather the same cooldown system from ME1. The vault opens into the next area and then you have to keep moving. Head up and to the right. More humorous banter follows and then more enemies to kill. Once you move out of that area, you will get a communication that one of your teams is pinned down to the left. Move and flank the enemies and pick them off from above. Once they are all down, jump down and a cutscene will play.
Once you regain control of Shepard, You'll see a hologram to the left. Approach it to listen to an historical record. There are several more such areas ahead. If people start talking over it, just exit the bluish circle and re-enter to start it over. When you're ready, head through the door on the opposite side and follow the catwalks.
When you emerge into the next room, move to take out any enemies in the immediate vicinity, then move to cover along the wall to find more enemies. Once the place is clear, head through the door at the end to continue. Moving through the next area more mercs will ambush you. Once they are down, grab the Med-Kit in one of the historical record areas and then move on. Once next the fight is over, there is a Terminal with Credits nearby and a Sniper Rifle High-Velocity Barrel Mod on the far right hand side of the room. Head over to the door and proceed. There is a Med-Kit stashed behind some boxes on the left before opening the second door.
Once the Atlas is dead, grab the Med-Kit at the base of the stairs and move along the catwalks. Use the elevated catwalk here to your advantage and keep pushing forward. Once the initial group is almost dead, Razor Squad arrives. Once you are done grab the Med-Kit on the boxes to the left and head through the door. In next room, everything suddenly gets quiet. Move along the path until you enter a large room. Kill the two mercs here, then look around for a Terminal on the right side with some Credits on it. Further down you will find a Sniper Rifle Ultralight Materials Mod in the middle and an Assault Rifle Ultralight Materials Mod on the left. There is a Terminal with some Credits at the far end just past where the mods are located. When you are ready, go through the door where the opposition came out and up the stairs.
When you emerge, you have to deal with some more enemies. Once they are dealt with, head through another door and up the stairs. Head through the hallway and down the corridor. Take your time exploring, and eventually you'll get a cutscene and dialog. Depending on your choice of dialogue, two Paragon Interrupts or two Renegade Interrupts allow you to threaten the two villains, though to no avail. Enjoy the rest of the cutscene.
In the ramp, you will find a confused Samantha Traynor. She'll need convincing, which you can do easily, but if you're romancing her, you'll have a Paragon Interrupt Opportunity to kiss her. After a cutscene, you and your squad will be under the CIC. Crawl to the end of the passage and hit the switch for the stairs. Run up and quickly find what cover there is, as there are plenty of enemies in CIC. When the area is clear, head through the door to the War Room to get Private Campbell’s Favorite Mug (yes, it is actually there the rest of the game), an Assault Rifle Thermal Scope Mod, and a merc PDA. When you've got that loot, next to the Galaxy Map is a Merc Payment worth 15,000 Credits. Before you head to the elevator, you will discover that "somebody" dumped all your personal stuff from the cabin - ship models, space hamster, medals - into a big bin for disposal. It's funniest if the hamster is there. Don't worry, you'll get it all back soon.
Get on the elevator. Once inside the Shuttle Bay, the Clone emerges in a full set of N7 Armor, and after a conversation, the fight begins. You'll have to fight your Clone, Brooks, and several more mercs. In the upper right corner of the HUD is a count of the Clone’s Medi-Gel. Your goal is to get the Clone’s shields/barriers and health gone to force them to use a Medi-Gel. There is a large crate of it in the center of the hold should you yourself run out. If Brooks goes down, the Clone will move to revive her, and there are an infinite number of mercs. So just concentrate on the Clone and avoid everyone else. There is an autosave in the middle of the fight where you get a cutscene. Continue the fight with the added challenge of not falling out of the open Bay Door.
Once you get the Clone to exhaust its Medi-Gel and get it down to half armor, the final cutscene will play. Both Shepards begin to fight, knocking them both onto the ramp, and eventually left dangling over it. Your squad saves the real Shepard, and you then can choose to try and save the Clone, who dies regardless. Your next choice is what to do with Brooks. A Paragon dialogue followed by a Paragon Interrupt will lead to you talking Brooks out of hacking the cuffs, and giving herself up. A Renegade dialogue will result in Brooks hacking her cuffs and making a run for it, leading to a Renegade Interrupt that allows you kill her. If you miss this last Interrupt, one of your squadmates will take the shot. After that, the Normandy returns to dock, and you wind up in your Apartment.
Several of your squadmates will want to meet somewhere in the Mall or in the Apartment. For most, they'll send you an email first, but some will just appear at a trigger point in the Mall. Some people will hang out for a bit after the cutscene, so be sure to talk to them again. To trigger meetups with squad and crew, you'll need to leave and return to the Apartment. You may even need to return to the Normandy and come back to the Silversun Strip. Here is a list of people you can meet up with:
Inside the Arcade are three games you can play. Getting the high score on each rewards you with a Weapon Mod.
-Shattered Eezo is a rock'em sock'em robots-type-game downstairs. Block until the opponent is charging, then wail on it. Also block when it's blocking, so you can avoid its first jab.
-Relay Defense is also downstairs. You're defending the planet on the right. Left-click on a square to launch a missile at an enemy. If too many of them manage to warp in and shoot your planet, you lose. Right-click to send a ship from right to left to add a score multiplier. This can be done three times, for a 4x multiplier. If the ship hits an enemy along the way, it and your current multiplier is destroyed.
-Upstairs is the Claw Machine. Using it is the easiest way to get the King of the Castle Accomplishment. Picking up an orange ball will get you a Weapon Mod, up to three times.
The Arena is a combat simulator, similar in idea to Pinnacle Station in ME1. Completing a scenario earns you a token, the quality of which is based on your score. Just inside the entrance to the right are three kiosks where you can redeem these tokens. You'll need to purchase everything in them to experience all the scenarios and get the Accomplishment. If you're worried that you're only getting silver tokens, you can exchange one Silver for three Bronze tokens. At the bottom of the stairs is the console you use to set up the scenarios. Once you Activate it, there are two buttons on the lower row: the one on the left exits the console, and the one on the right is the Arena email program, where you'll receive challenges. The upper row of buttons are the options for the scenarios. More of them will unlock as you redeem tokens. When you've gotten your next scenario set up, go through the door to the right. On the other side of the partition are a Weapons Bench and Armor Locker. To the right of that is the door to the combat simulator.
Each scenario runs three rounds. At the start of a round, you'll see a drone with a scoreboard in the upper right area of the screen. It follows you around and generally makes a nuisance of itself. Just try to ignore it. You'll also see a cluster of glowing orange points that look like onions. These are the spawn points for the enemy in this round. You'll have a few seconds to position yourself before the round begins. Enemies will spawn in waves. Killing enemies within five seconds of each other gets you a killing streak bonus, up to ten in a row. When they're all eliminated, the round ends. A large blue hologram that looks like a crystal will spawn. Run through it to get 200 bonus points. At the end of the match, your score is totaled, and multiplied based on the modifiers you've given yourself. Don't worry too much about the Accomplishment for scoring 9999 points, because you'll get there soon enough.
When you've completed all the challenges and unlocked everything from the token kiosks, you'll get a series of challenges from the programmers of the Arena. The final one will be buggy with the safeties turned off. If you get knocked out, you die and have to reload from your last save. There are four rounds of mixed enemies. Survive it and you'll get the Accomplishment.
When you've done everything you want to do in the Mall, return to the Apartment. Use the decor console to put in place some new furniture, if you want to. Time for the Party.
Use the email terminal to send out invitations. Some people are automatically invited and can't be un-invited. The availability of others depends on who's alive and who's completed their Missions in this game. Once the invitations are sent, Talk to Glyph to choose an ambiance. This can be either subdued or lively. No matter what, people will get drunk. Talk with everyone, and then Glyph will offer to keep the ambiance the same or change it. Talk with everyone again, and Glyph will offer to take care of one issue, if any has arisen. In between each round, run between groups multiple times to hear all they have to say. When you're ready to finish the party, go to the couch to take a group photo.
In the morning, you may wake up next to your love interest, or someone else. Talk to everyone to see how they deal with hangovers, then go to the Mall. When you're done with everything here, Activate the Citadel Rapid Transit to return to the Normandy. There's one last cutscene. After the party you may get more emails. Return to your Apartment to check your messages if you think you may have missed anyone.
