Earth, 3666. Society has collapsed.
Technology-fueled civil wars have left the planet in ruins. Amid the chaos, a secret group called the Doppelganger Studies Institute (D.S.I.) develops perfect human replicas—doppelgangers—to infiltrate and control what's left of civilization.
But the system broke. Some doppelgangers are flawed. Unstable. Dangerous. And now, they’re trying to enter your building.
You are the last line of defense. You are the building security guard.
Your mission: detect and stop doppelgangers at the door. Using ID checklists, face scanners, document checking, and CCTV surveillance, you must verify every visitor. In this intense security guard game, one mistake could mean letting a killer inside.

This is not just a job. It’s survival.
Doppelgangers mimic humans perfectly—until they don’t. Some slip up. Your eyes, logic, and tools are all you have. This security simulation puts you in charge of life-or-death decisions.
Do you have what it takes to be the perfect security guard?
