Gnosia TV Anime
The game was originally released for the PlayStation Vita in Japan in 2019, followed by a port to the Nintendo Switch in 2020. In 2021, Playism published the game digitally for the Nintendo Switch in North America.
Playism provides the following description of the game:
“Let’s walk and talk.
Can you get up?
The Gnosia lie. Pretending to be human, they’ll get in close, trick and deceive, and then eradicate each person in the vicinity from the universe, one victim at a time.
The crew of a drifting spaceship, facing off against a mysterious and deadly threat known as the ‘Gnosia’ and having no idea who among them is truly the enemy, devise a desperate plan for survival.
The most suspicious among them will be put into ‘cold sleep’ one by one, in an attempt to completely rid the ship of Gnosia.
However, it is nearly impossible to tell whether each person placed into cold sleep is genuinely Gnosia, or merely an unfortunate scapegoat sacrificed by the Gnosia for their own survival. Can the humans succeed in their fight? Or is mankind doomed…?”
Playism also launched the game on PC via Steam in January 2022. The game was then released globally for PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S in December 2023.
