More about Lost Sanity: Cthulhu

Lost Sanity: Cthulhu is the FIRST chapter of a horror anthology where Halloween night stories come to life. Players experience a cosmic horror narrative as Megan Claire, a former reporter, awakens in a sunken city prison. The game emphasizes psychological tension over jump scares, requiring stealth, environmental observation, and strategic movement to survive cult rituals that threaten reality. Each chapter reveals a world between flickering candles and imagination, with the first chapter focusing on a silent cosmic entity and cultists tearing open reality. The game rewards players who think like shadows, using silence and observation to evade threats that include both cultists and unseen entities.
