Security 51 Anomalies and Inspection Tools

What official sources confirm about anomalies, fingerprint checks and blood tests in Security 51.

Released factsLast checked

Official descriptions confirm that the checkpoint eventually adds more precise identity checks and asks you to identify non-human or anomalous cases.

Tools unlock with experience

Fingerprint verification and blood testing are named as later inspection methods. The unlock shift and exact interface are not confirmed, so this guide keeps them as capability notes.

Officially described examples

  • A camera shows an empty elevator, but a person is present when the doors open.
  • An employee who already left appears again from the underground area.

How to use the signal

Cross-check the observation against the person's record, then quarantine when the case remains suspicious. Do not infer a fixed outcome from one anomaly until a playable build verifies it.
