Anomaly 404 is a first-person psychological horror game built around observation and doubt. After receiving an anonymous letter about monstrous experiments, you infiltrate the Void Corporation bunker armed only with a camera. Inside "Project 404," conventional logic begins to crumble, and the only way to survive is to notice what shouldn't exist. Doubt as a tool Every corridor and room looks almost identical, but details change. Objects shift, lighting distorts the space, and the environment seems to repeat itself with subtle differences. If you notice an anomaly, capture it on camera; if not, keep moving forward, hoping your memory is correct. The deeper you descend into the bunker, the stronger the sense that reality is unstable. Space can deceive the eye, and fear makes you doubt even the obvious. Strict rules conceal a tense atmosphere where attention to detail becomes the only way to get closer to the truth. Features of the game Spot-the-difference gameplay in 3D space. Photographing anomalies as the main mechanics. Psychological pressure and distortion of perception. A story about secret experiments and a military corporation.
