Amnesia: The Dark Descent

Survival horror set in an 1839 Prussian castle where you play Daniel, a Londoner who wakes with fragmented memory and a self-written note ordering him to kill the castle's baron. You can't fight the creatures stalking these halls—your only options are hiding, running, or watching your sanity fracture. The game tracks mental state: stay in darkness too long or witness disturbing events and Daniel's vision warps, controls become erratic. Managing light sources (oil for lanterns, tinderboxes for candles) against the need to avoid detection creates constant tension. You'll solve environmental puzzles to progress deeper while piecing together why you erased your own memory. It's built for players who want dread over action.
