You're a security officer deep within Area 51. Scan the staff, verify clearances, and decide who can enter the elevator and who absolutely mustn't leave. The deeper you go, the less certain you are that anyone standing before you is still human.
Modeled estimate, not a reported figure. How we estimate →
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.
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.
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.
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.

Está chido
Игра неплохая, но пока что в ней куча багов. Фото отображаются неверно, игра в разные миссии отдаёт приоритет разным указаниям инструкций (игнорируют в каком порядке они написаны). Если не хотите играть методом проб и ошибок - лучше подождите пол годика, может и поправят.
好難玩,不明白實驗室有何用,什麼找零號病人,到了10幾日上方城巿會過高病毒輸了,原來是每日開始時要留意有無新對策增加城巿控制比例,新對策出現要試驗室用不同試驗得出新對策。現在玩到第三級權限了

Good stuff!
Muy corto, pero entretiene, no es un papers please ya que la historia no atrapa tanto, de hecho casi nada pero aun asi esta bien, lo recomiendo si se puede en oferta, pero sacarle mucho mas de lo que yo jugue pues, a menos que te guste mucho repetir indefinidamente pues eso.
I really enjoyed this as a fun chill game of following instructions. My only complaint is the rapid blood test colors were far too similar and made it difficult to get those right.
pretty good. a little confusing at times with the mechanics, but it's a fun game. i love paperwork-type games
its ok
Great game for fans of Papers Please and the like! Very Addicting!
el juego aunque simple y algo fácil me estaba gustando, pero esa (nisiquiera se como llamarlo) con la que salieron en el día 27, me quitaron todas las ganas de jugar, no se a quien se le ocurrio eso en lugar de ir aumentando la dificultad y añadiendo nuevas mecanicas, pero es horrible, no explica nada y lo que dan es ganas de cerrar el juego
