France, 1916. French soldier Henri Clement wakes alone in a WW1 bunker with no memory of how he got there. The exits are sealed. His comrades are gone. Something lives in the walls — large, relentless and drawn to sound. Henri has a revolver with a handful of bullets, a hand-cranked dynamo torch, and whatever he can scavenge from the rooms he dares to enter.

Amnesia: The Bunker is the most mechanically ambitious game in Frictional Games' catalogue, departing from the linear structure of its predecessors for a semi-open sandbox horror. The bunker is a single interconnected space that the player must manage as a whole rather than progress through sequentially: doors can be blown open with grenades, resources are finite and non-replenishing, and the generator that powers the lights must be manually wound every few minutes or the bunker plunges into darkness. The creature responds to sound — gunshots, running footsteps, explosive blasts — and its AI-driven patrol means every encounter is different. Items can be combined and used creatively; the physics-based world rewards improvisation. Each attempt to escape requires a different sequence of problems to solve across the same space, making the bunker feel genuinely dangerous long after its layout is memorised. Steam Workshop supports community-created content.
