What is Room 404?

This first-person horror walking simulator takes place on the fourth floor of a Chinese apartment building. You repeatedly inspect the corridor, advancing when you detect an anomaly and turning back when nothing changes, while piecing together the tenants’ stories. Some anomalies reveal glimpses of a possible past or future.
