Gnosia

Gnosia is a 2019 visual novel social deduction role-playing game developed by Petit Depotto. It was originally released in June 2019 for the PlayStation Vita, and was ported to the Nintendo Switch in December 2020, with a Windows version released in January 2022. It also released for PlayStation 4, PlayStation 5, Xbox One and Xbox Series X/S in December 2023.

Aboard a spaceship, the player and several NPCs must deduce who on board is a Gnosia, an alien-like creature that will kill the regular humans on board. The player works with the NPCs to suss out and nominate the potential Gnosia suspects and put them into cryo-sleep. The player can also be Gnosia, in which case they know the other Gnosia on board and will work together to try to eliminate the humans. The number of Gnosia as well as the number of NPCs on board as well as the player's role, is determined prior to each loop beginning. In addition to regular humans and Gnosia, there are other roles, including the Doctor (who can investigate the recently frozen NPCs and determine if they were human or not), the Engineer (who can investigate non-frozen characters to determine if they are human), the Guardian Angel (who can protect high-risk targets from elimination by the Gnosia), Guard Duty (who are 2 guaranteed humans who can vouch for each other), Anti-Cosmic Follower (also referred to as AC Follower; who is a human that sides with the Gnosia), and the Bug (who is essentially playing for themselves, trying to stay alive to the end of the round and seizing victory for themselves, destroying the universe).
