Security 51 v1.1.1.219

Security 51 is a horror security simulator where you work the night shift at an underground bunker in Area 51. You must verify identities by checking names, positions, clearance levels, and documents, then use fingerprint analysis, blood tests, UV lights, body scanners, and cameras to detect anomalies. Quarantine suspicious personnel, follow protocols, and face consequences for your decisions across multiple shifts with different endings.
