Compare Noosphere prices across trusted key stores and find the best deal. Developed by KOEX studio. Published by GrabTheGames. Released on 7/23/2021. Available on PC. Genres: Adventure, Indie.

A haunting first-person puzzle game about shared consciousness that trusts you to piece together its fractured narrative without handholding.

I spent an unquiet evening inside Vincent's fractured mind, navigating claustrophobic spaces where another entity whispers from within. Noosphere is a psychological horror puzzle game that leans hard on atmosphere and implication over jump scares. The puzzles feel deliberately obscure, rewarding observation and lateral thinking rather than obvious progression. Exploration is slow, methodical, and eerie in ways that reward patience. This is a game made by one person, and it shows in both its strengths and limitations. The soundscape carries more weight than the visuals alone could manage, and there's a real sense of intentionality in what isn't explained. The pacing won't suit everyone, there's no combat, no urgency, just the creeping dread of sharing your own skull with something else. If you prefer puzzle games that respect your intelligence and don't apologize for their strangeness, Noosphere is worth the quiet hours it asks of you. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
