Puzzle solutions & keypad codes
Some locks use a fixed number; others ask you to read the clue in your own game. Match the location before entering a code.
In this guide
Entrance: assemble the two fragments
Find both torn fragments and read the combined admission code.
The admission keypad is not the Gift Shop basement. If a copied number fails at the entrance, look at the two fragments you collected instead. Keep all digits in the order shown by the assembled clue.
Fixed-code quick reference
Check the lock’s location, not just its appearance. A four-digit keypad in another room is not interchangeable with one of these doors.
| Location | Code | Use it for |
|---|---|---|
| Gift Shop basement | 1903 | Access to the basement fuse route |
| Foreman’s Tower | 0451 | Tower entry; operate the red control inside |
| Later elevator access | 1677 | The elevator-side access sequence |
| Dynamite storage | 0180 | The storage locker; include the zero |
Field laboratory: read the workstation
Repair the keypad, then use the password on the field laboratory workstation.
Find the replacement component using the upper platform route. Once the panel is repaired, return to the workstation clue. If the panel does not accept input, finish the repair before retrying the password.
Theater repaired, but nothing plays?
The timing repair and the presentation control are two actions. Complete the three indicators, then use the separate player control. A powered circuit is only the first half of the sequence.
Four fuses: use a route, not a blind search
The rail-cavern stops are the generator bench, lower office, upper office and locked trackside shed. The shed needs the key from the elevated cabinet near the Call It In stairs.
Open the four-stop locator and tick the route task when the panel is ready. If the completed panel will not respond in the second Allo encounter, check the 1.0.9 fix before starting a new save.
