This is a horror-adventure game in which players assume the role of a man attempting to recover from self-induced amnesia. From a first-person perspective, players navigate castle environments, solve puzzles, and avoid zombie-like creatures. When players are attacked, splashes of blood appear on-screen; large bloodstains and pools of blood are also visible in some areas. Players can encounter human corpses lying on the ground: some are nude with visible male genitalia, while others are decapitated or dismembered (e.g., bloody torsos, severed arms). The word "sh*t" appears in the dialogue.
