Lost Sanity: Cthulhu is a first-person psychological horror game structured as an interactive anthology. On Halloween night, a group of teenagers gather to tell horror stories, and each tale becomes a playable chapter. In the first chapter, "Call of the Sea," you assume the role of Megan Claire, a woman trapped in an underground prison where occultists are conducting a ritual to awaken an ancient marine entity from the depths beneath the city.

Gameplay emphasizes exploration, investigation, and stealth mechanics rather than direct confrontation. You must navigate claustrophobic environments, follow environmental clues, and avoid detection by cultists while uncovering what is happening in your prison. The core loop involves observing your surroundings carefully, solving environmental puzzles, and managing your psychological state as you progress toward escape.

The game's defining characteristic is its approach to horror through psychological tension rather than jump scares. Lost Sanity: Cthulhu cultivates a persistent sense of dread and the creeping feeling of being watched or evaluated. Danger often waits silently rather than rushing toward you, creating sustained unease that lingers throughout your playthrough. The sanity mechanic ties directly to your character's mental state as you witness cosmic horrors and uncover disturbing truths.

As an episodic horror anthology, the game promises multiple chapters beyond the initial "Call of the Sea," each introducing new stories and protagonists. This structure allows for varied settings and narrative perspectives within the Lovecraftian framework. The title is designed for players who appreciate narrative-driven horror experiences, atmospheric world-building, and psychological dread over action-heavy gameplay. It appeals to fans of cosmic horror fiction and those seeking a slower-paced, contemplative approach to the survival horror genre.
