Projector Room Puzzle

The projector room puzzle lives on Floor 1 and unlocks the metal boxes in the theater that lead to the Dinner Plate puzzle and the Cold Chisel.

1. From the 1st Floor, go right to Door 6 and on the right section enter through the doorway with the light.
2. In the dining room, interact with the 3rd door on the right and ascend the stairs.
3. Pick up the USB Adapter near the boarded door.
4. Combine the USB Adapter with the USB Cable (from the bar in the bottle puzzle) into a USB Charger.
5. Back on Floor 3, enter the purple door left of the broken TV and use the USB Charger near the wall outlet and phone.
6. Then on Floor 1, go left to Door A and input the code shown in the Old Book.

Each Film Canister is loaded into the projector in turn:

• Devora 1 (Canister 1) → unlocks the first metal box in the theater → needed for the Dinner Plate puzzle.
• Canister 2 (Ivan statue) → unlocks the second metal box → drops the Cow Skull.
• Canister 3 (Cursed Film Canister, purified) → unlocks the third metal box → the Cold Chisel.

Watching the full film on the projector is what unlocks the Cold Chisel pickup. The canisters chain is on the film canisters page; the full walkthrough walks through the Floor 1 → Floor 3 → Floor 1 loop.
