Demo codes and puzzle help
For the demo's painting-hallway cabinet, enter 9901. TerabyteTerry's demo-specific guide was published on 18 September 2026, before the full game's release. The room is identified by the Marlowe and Prophet paintings.
What I checked
We checked the YouTube source's title, creator description and 18 September upload date on 14 October 2026. It explicitly covers the demo's painting puzzle and code 9901. This is a player-recorded source, not a claim that this website completed the demo.
Painting cabinet: 9901
The 11-second demo painting-puzzle guide identifies the Marlowe and Prophet paintings and gives the cabinet combination as 9901.
GamesRadar's release guide places the corresponding cupboard in the red hallway after obtaining Bruno's keycard and gives 0199/9901 for the full game. Only 9901 is established by the demo-specific source used here; 0199 is not presented as a tested demo alternative.
- Find the painting hallway and identify the nearby Marlowe and Prophet painting plaques.
- Interact with the cabinet's four-digit keypad.
- Enter 9901. If you are looking at another container, match its room before using this combination.
Looping corridors and the box
The release Prologue guide says to reverse direction when a real-room scene appears in the Labyrinth loop. Near the exit, use the Genesis Configuration prompt to transfer fire between pillars and manipulate blocks. See Find Sunny for that opening route.
Steam says the demo introduces puzzle solving, crafting and combat; the full weapon upgrades, box powers and more complex puzzles belong to the complete game.
Other locks and full-game differences
The full-game medical locker uses 9891 and is identified by the body in the tub. This page does not establish its presence or behaviour in the demo. Later campaign lockers must not be treated as a demo combination list.
- Cult opening route covers the Tongue Key and Leviathan statuette.
- Full-game code table labels the later locations.
- Later Genesis box shapes are a full-game guide, not a claim that all five appear in the demo.
When an interaction will not respond
The official 21 September demo patch addresses stuck movement, frozen input, incorrect tutorial hints and disappearing objective messages. Use the announcement links and check the installed build before treating a frozen interaction as a wrong code.
Questions
Do all full-game codes appear in the demo?
No such overlap is established. The demo contains only the Prologue and part of Episode 1.
Does solving the demo unlock progress in the full game?
No. Steam explicitly says demo progress does not transfer.
