About Demon Core
Demon Core is a short, semi-linear psychological survival horror game set inside an old nuclear power plant in Gray Bay. You explore its irradiated interior in a radiation suit, relying on a paper map and geiger counter to find your way and survive. There are no waypoints, and navigation is up to you.
Explore the plant
Heavily irradiated areas and nuclear waste litter the corridors. You must watch your geiger counter and plan your route as you search for the monstrous cause of the plant’s sudden reawakening. Detailed visuals, sound design and frightening lore shape the atmosphere.
Evade what stalks you
An intelligent, highly irradiated presence stalks the plant. Combat and escape are not options, and the game focuses on tension and release rather than parkour chase sequences.
