About GNOSIA

✦ AI summary

Identify the shape-shifting Gnosia imposters hidden among your spaceship crew through discussion and deduction, voting suspects into cold sleep while uncovering mysteries across repeating story loops. Master different roles with unique abilities and stats to manipulate debates, gather intel from diverse crewmates, and survive increasingly complex rounds of social deduction.

The Gnosia lie. Pretending to be human, they’ll get in close, trick and deceive, and then eliminate 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 really the enemy, formulate a desperate plan for survival. The most suspicious among them will be put into “cold sleep” one by one, in an effort to rid the ship of Gnosia.

Gnosia is a Sci-Fi Social Deduction RPG in which you will engage in discussion with a variety of unique characters, with the aim of identifying the Gnosia among the group. Players will have to use what information they can gather during the discussions to ascertain whom they think is Gnosia and then vote to put them into cold sleep. As you progress, your abilities will improve - but so will those of the crew.
As the numbers of crew members, Gnosia, and various “roles” increase, it will become increasingly difficult to determine who is telling the truth. Work in collaboration with or against other crew members to ensure your survival until the end.

・Repeatedly play through “loops”, triggering special events to unravel mysteries in a uniquely original narrative. Certain events will unlock new commands for you to use during discussions.

・Step into a variety of roles to develop different character builds. Your stats will determine how effectively you can sway the group’s opinion or lie, and will also affect your likelihood of being selected for cold sleep.

・Engage with an engrossing and eclectic cast of characters and experience randomly triggered events, each one unique to its subject. Character events will reveal information about your crewmates in the form of special “Notes”.

✦ AI summary

GNOSIA is a social deduction game praised for its engaging core gameplay loop, well-developed cast of distinct characters, and compelling time loop narrative that rewards repeated playthroughs. Players highlight the refined logic system, strong writing, and atmospheric music and art as standout elements, with many finding it surprisingly addictive and emotionally resonant despite its simple mechanics. Most players consider it a hidden gem worth experiencing, particularly for those who enjoy mystery stories and single-player deduction games.

experienced looping phenomenon when playing

An absolute masterpiece with a stunning watercolor aesthetic, unforgettable vibe, and endless replayability. It flawlessly adapts social deduction into a solo RPG, beautifully driven by a brilliant time loop narrative and a non-linear scenario.

Very fun and relaxing game to play once you understand the perks of it. Characters are lovely, the artstyle is quite charming, making the "story" (characters' background) really enjoyable to find out about. Overall very good experience, and again, once you understand how to influence NPC's choices, it never gets frustrating. Also goated soundtrack

It's fun single player social deduction game with interesting story filled with mysteries. And of course characters are interesting with likeable or unlikeable parts (which might changed based on your situation), so because of the story who aren't into this genre of this game (social deduction) can have fun and enjoyable experience when playing this game. So of course who like social deduction games that of course they also will have fun and enjoyable experience. By the way, in my case, thankfully I played this game before watching anime. For some watching anime before playing the game would ruin the game's experience for others not. I think I would have been in foremost category.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
