About this game
A cryptic note draws you to an old mansion on a stormy night. Inside, the halls stretch and twist in ways they shouldn't, and the air is thick with something unseen. As you explore, you must solve cryptic puzzles, confront the residents, and unravel the past.
SOMNIFUGE is a first-person psychological horror game blending exploration, puzzle-solving, and surreal horror. Inspired by the haunting atmospheres of Silent Hill and Alone in the Dark, it embraces PSX-era visuals to create a world that feels both nostalgic and deeply unsettling.
From the creator of the popular indie horror shorts Burger & Frights and Dreader, SOMNIFUGE delivers a tense, atmospheric horror experience where nothing is as it seems.
Features:
The World: Explore the haunted mansion, a maze-like library, a twisted hospital ward, and more cursed locations.
Puzzle Solving: Crack the many cryptic puzzles.
Survival: Meet and escape the host of horrors.
Controller Support: The game has full 360 controller support.
