GUIDE_SCOPE.TXT
Selected content from the 2008 campaign, without expansions or mods. The Project Purity entry reveals the ending solution. Standard terminals use variable words; puzzle combinations are listed separately.
Before looking for a password
This guide covers selected access methods and campaign locations. In Fallout, a collected password may act as an inventory item, unlocking the terminal automatically. Minigame words change, so use the likeness logic explained below.
For locks, adjust the bobby pin and turn gently. If it jams, release and reposition it; forcing it breaks the pin. A door marked “requires key” needs the item or mission progress indicated in the guide. COPY buttons appear only for fixed solutions.
Likeness counts correct letters in the correct positions.
REWARD / EFFECT
Terminal access without a previously found password.
HOW TO SOLVE
Choose a word and read its likeness. For example, if COLD returns 3, GOLD is compatible because O, L and D occupy the same positions; this is not yet a certainty. Compare each candidate with all previous attempts. Select complete symbol groups enclosed in (), [], {} or <> to remove dud options or restore attempts. Exit before using the last attempt if unsure; when you return, reassess the new list.

Terminal hacking requirements
LOCATION
Difficulty shown when targeting the terminal.
CLUE / REQUIREMENT
The Science requirement is 0 for Very Easy, 25 for Easy, 50 for Average, 75 for Hard and 100 for Very Hard. Science lets you start the minigame but does not provide a universal password.
REWARD / EFFECT
Lets you start hacking at the corresponding level.
HOW TO SOLVE
Check the requirement before spending time searching for a combination. If the screen says a specific key or password is required, find the mission credential; increasing your skill may not solve it.

Museum atrium and West Wing.
CLUE / REQUIREMENT
Prime leaves numbered messages; the answers are prime numbers.
REWARD / EFFECT

On the lower floor of the Delta IX exhibit, on the north wall, choose 113 in #003 and select Get Passcode. These are answers on three computers, not one concatenated code.

Activate these in order: broken radio, glass pitcher, garden gnome, pitcher, cinder block, gnome and empty bottle. On the terminal that appears, read the options and activate Chinese Invasion to end the simulation through this route. Then exit through the playground door.
