Anomaly Control Division is a first-person surveillance horror game in which you play as a newly appointed administrator assigned to survive a night shift inside a containment facility. Your duty is to monitor three containment chambers via CCTV from 00:00 to 06:00, detect anomalies involving each entity, and carry out the correct procedures. The Tentacle Swarm, the Mimic, and the Bound Circuit each exhibit unique behaviors, risks, and abnormal phenomena. As the night progresses, they become increasingly unstable, and a single mistake could trigger a facility-wide containment failure.
