Nightsolo's Short Fallout Walkthrough

Notes:

This walkthrough assumes you have read the manual in the game's installed folder (and also here).
This walkthrough assumes you want to get through the game as quickly as possible, while still being good.
"Area" means a sub section of a city. i.e. where you cross the green area.
Many of the steps are dependent on your character's skills. For example, if you're supposed to tell someone something specific, you may not have that dialog option if your character isn't smart enough.
No side quests are discussed here, this is just a quick rundown on the main quests.

From Vault 13, go west and a little north to find the Military Base, kill all the mutants outside. Search the mutant closest to the door for an encryption holodisk. Read it. You can now open the door.
Clear out every level of mutants and robots.
On the 4th level, Kill the Lieutenant and his guards, then loot a locker nearby for a Key, which you may use later. There is a room in the northwest corner with a bunch of computers in it. One of them is the master computer.
Establish an interface with it, then use it to download as many logs as you can. Execute one of the commands. This will set a timer for the self-destruct of the base. Choose the right one or you won't have enough time to get out. If your character is stupid, you can also set a timer on an explosive, then drop it in front of the computer. Stand in front of the elevator and wait for the bomb to explode. You then have 120 seconds to get out, which is plenty of time.
Next stop, Boneyard. Head south to what used to be Los Angeles. From the entrance, exit north on the green grid, then go east. Find Nicole in the building with the circled cross on the front. (you may have to go at daytime to find her) and ask her about the Children of the Cathedral.
Just scout out The Cathedral by going there, then return to Nicocle and ask if there's anyone that can help you.
Back at The Cathedral. Find and talk to Laura in a room on the west side. Ask her to open the door she's talking about. If she won't talk to you, steal a radiation symbol from the man in front of the stage, or lockpick the door to the north of him. Or kill everyone.
Go upstairs. Go up the flights of stairs, killing everything on each level. Search Morpheus for the key to the locked door downstairs.
Go through that door, kill the mutant there, and go down the stairs.
Go to the southeast corner of the "basement" and try to open the crack in the wall. Or use some explosives. Or wait around a while, and a robed guy will come out and ask you what you're doing there. Kill him and the beasts inside the now open wall. There is a Vault in the caves there.
Go in and kill all the mutants inside.
Free the prisoners on the south side of level 2. Now there are three ways to finish the game.
1. Kill the Master. He's the overseer in this vault. When you're talking to him, don't piss him off or your chance-to-hit will go negative. When he gets pissed off and you end up fighting him, I recommend using plasma grenades on him.
2. Talk the master into telling you his flaws.
3. Set off the warhead on the 4th level. Your lock-picking skill needs to be really high to get past the elevator door, and the door in front of the elevator on the 3rd level. You either need a very high Science skill, or a special Key from the locker near where you killed the Lieutenant in the Military Base. Use it on the computer in the bomb room.

THE END

Congratulations. The ending scenes are scripted based on what you did during the game.
