FAQ
Can I miss any of these codes?
Most main story codes are unmissable because the puzzles block your path. Optional safes and lockers can be skipped, but you can backtrack to most areas if you missed something.
Do codes change between playthroughs?
No. All safe codes, locker combinations, and door passwords are fixed. They do not randomize.
Where do I get bolt cutters?
Bolt cutters are found in the basement. They are required to access the Family Photo room on the 1st floor.
Where do I get solvent?
Solvent is located in the 2nd floor storage room. Use it to remove the adhesive holding the coin near the first restroom.
What happens if I shoot the nurse on the couch?
If you shoot or grab the nurse sitting on the couch in the 4th floor duty room, the 2-coin reward will not spawn. Leave her alone and exit the room to trigger the "thank you" event.
How do I find the Shutter Door Key?
Examine the file in Room 307 on the 3rd floor. The key is hidden inside. Use it on the shutter door box, then close the shutters to collect 3 coins.
