ALIBI
Six divers are sealed in a research station while a storm rages above. One of them is killing the others. Every suspect is an AI agent with its own memory of the night, and the killer lies.
How to play
- Move with WASD or the arrow keys, or click or tap where to go.
- You only see who shares your room or tube.
- Stand on a dashed ring and hold E to do a task. Each task gives you one true sonar log.
- Find a body and report it. Everyone gives an alibi. Question them, then vote.
- The storm clears after three meetings. If the killer is still aboard, they win.
The twist: pacts
- The killer may corner you and offer a deal: vouch for them and win with them, or take the knife and swap roles.
- Refuse, and you know who it is. Can you convince the others?
- As the killer, make the same offer. Some accept, some refuse, and some only pretend.
