Gnosia is an indie adventure role-playing game. The crew of a drifting spaceship, faced with a mysterious and deadly threat known as Gnosia, and with no idea who the enemy is, formulate a desperate plan for survival. The most suspicious of them will be put into "cold sleep" one by one in order to completely rid the ship of Gnosia. However, it is almost impossible to tell whether each person in the cold sleep was actually Gnosia — or just a poor, unfortunate scapegoat that Gnosia sacrificed for its own survival.
