Security 51 Free Download

Security 51 is an atmospheric horror security simulator set in the underground bunker of Area 51, where you must decide who is allowed to enter and who should never be allowed out. Check documents, clearance levels, identities, and suspicious behavior while using increasingly advanced verification methods to uncover anomalies and possible infiltrators. Investigate strange incidents, quarantine suspicious personnel, and make difficult decisions as the line between human and something far more dangerous begins to disappear.
