Content notice: Since the graphics are retro, the extent in which they are graphic is limited, the creature that hunts you in this horror title will leave behind blood splatters and bodies will ragdoll, future plans for maybe adding more gore to certain rooms like a torture room but again the graphics will be retro so not overly gorey
Last updated 28 Sept 2026
