About Anomaly 404
Anomaly 404 is a first-person psychological horror game in which you infiltrate a secret military bunker as a journalist to expose the truth about Project 404. You search for anomalies and photograph them, but your eyes may deceive you. The gameplay is based on spotting differences: take a photo when you see an anomaly; if there is none, keep moving without taking one.
Search the locations
You explore multiple eerie locations, inspect and interact with objects, and use your camera to capture anomalies. The game contains over 100 anomalies. A 3D progress board tracks your search status, while losing sanity makes anomalies harder to find.
Uncover the story
You can read story documents to learn the dark lore and discover the main and secret endings. The game also includes regular and secret achievements, along with high-quality sound and a tense psychological horror atmosphere.
