About This Game

A team of explorers arrives at a new site and discovers something inexplicable. Their colleagues have become possessed by restless spirits - they are now "altered." Are you certain about the people you trust with your life?

In this place, every spell spoken aloud carries real consequences - for you and for everyone around you.

Multiplayer for 4–8 players.

Utter the spell aloud - and a door will open, a trap will trigger, or an enemy will fall.

Pretend to be one of them. Sabotage. Kill.

You have everything you need to expose the other one. But will the others believe you?
