EXPEDITION TO THE BACKROOMS
EXPEDITION TO THE BACKROOMS is an atmospheric exploration game focused on wandering through quiet, unsettling environments.
Inspired by the Backrooms internet horror phenomenon, the game takes players through strange and isolated spaces hidden beyond reality. Explore abandoned office areas, flooded complexes, and other unnatural environments connected by the endless maze of the Backrooms.

Each area offers its own sense of scale, isolation, and mystery, ranging from familiar office spaces to surreal and impossible architecture.
ATMOSPHERIC VISUALS
Built with a strong focus on lighting, materials, scale, and immersive sound design.
Experience detailed liminal environments designed to feel quiet, believable, and deeply unsettling.
