About This Game

A "SIMPLE" JOB

Security 51 is an atmospheric security guard simulator inspired by Papers, Please, and SCP paranoia. You're on duty in the underground bunker of Area 51, where the most dangerous part begins at the elevator: the shaft descends for miles down to unknown levels. Whether it's laboratories, anomalies, inhumane experiments, or something alien—you're not supposed to know. Your task is simple: let in those who have access and stop those who don't... even if everything looks "right" on the surface.

SECURE, CONTAIN, PROTECT

Everyone who passes through your checkpoint carries papers and passes. Your job is to check names, positions, clearance levels, and time, ensuring the number of people entering and leaving matches, and pay attention to any oddities. As time passes you'll catch yourself thinking that something's wrong more and more, and the only thing to rely on will be the protocols. But even they can be wrong.

TOTAL CONTROL

With experience, you'll gain increasingly more accurate methods of identity verification, such as blood testing. Did that janitor simply open the wrong door, or are they a spy for an enemy government? Or are they not even human? When in doubt, quarantine the suspect. Sometimes you'll make mistakes and lock up an ordinary employee, and sometimes you'll find a titanium cell ripped open from the inside. Some decisions will have immediate consequences, others only after several shifts.

CONTAIN THE THREAT

The consequences of every mistake go far beyond issues in the workplace. Let the wrong person out, and the infection will ravage the city. Isolate suspicious employees, investigate anomalies, and launch new operations to contain the threat before it's too late.

Remember, it's not just about who you let in, but who or what you let out into the world.
