Photophobia 2025

Photophobia is a psychological horror game built around echolocation-based navigation. The player sees by making sound. Footsteps, jumps, and even speaking into the microphone send out waves that briefly reveal the surroundings. The game is built in Unreal Engine. Its post-processing effects draw the waves with edge detection and scene depth, and a custom ring decal system adds spatial awareness, giving players brief glimpses of their surroundings.
