About Lost Sanity: Cthulhu
Lost Sanity: Cthulhu is the first chapter of Lost Sanity, a horror anthology in which stories told by teenagers on Halloween night become playable chapters. This chapter takes about 1 hour and 30 minutes. You play as Megan Claire, a former reporter who wakes in an underground prison and must survive and escape.
The cavern and the ritual
Cultists gather in an isolated cavern to perform rituals that are gradually opening a passage between the mundane world and the unfathomable. In a sunken, forgotten city, a cosmic entity waits in silence. The chapter, titled Call of the Sea, follows Megan’s struggle to escape as the ritual advances and the danger grows.
Survive in silence
Stealth is essential. You move quietly, observe patterns and use objects in the environment to divert attention and create chances to flee. Noise can draw the cultists and the entity they worship.
Uncover what happened
You interact with objects, find lost notes and forgotten artifacts, and piece together the cultists’ timeline and how Megan ended up in the prison. The horror builds through psychological tension and the sense of a presence watching or waiting in the darkness, rather than relying only on jump scares.
