What is GNOSIA?
This single-player sci-fi social deduction RPG takes place aboard a drifting spaceship where some crew members are secretly Gnosia. You debate with the crew, gather clues, and vote to put suspects into cold sleep. Across repeated loops, you take different roles, improve your stats, and uncover character events.

What players say
94% of 5,147 reviews are positive · 98% of 71 in the last 30 days
Players praise the cast, sci-fi story, art, and music. Their most common complaint is that debates repeat stock dialogue, while story events can take many loops to appear. Some say votes feel driven more by stats or unpredictable crew behavior than by deduction.
