GNOSIA is a sci-fi game about a werewolf party. The spaceship is overrun by aliens known as the Gnosia, who can take on the form of humans; players must talk to everyone on board to try and determine who is human and who is actually Gnosia. Players can force any character into cryostasis one at a time in order to neutralize the Gnosia, leaving the people standing. Players win if they suspend all Gnosia, but lose if they accidentally suspend people and leave Gnosia awake. The round lasts about 15 minutes, and the roles of the NPCs are randomized each time, so each round is unique. However, it is almost impossible to tell whether every person who fell into a cold sleep was in fact a Gnosia or just a poor, unfortunate scapegoat whom Gnosia sacrificed for her own survival.
