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.

Esta bastante bueno, pero siento que le falta ambientación, mejores sonidos o sonidos mas característicos, mejor musica, etc, todo lo demas esta bastante bien
O jogo tinha muito potencial em ser um "sucessor" de "Papers Please" mas é uma grande decepção. A história é fraquíssima e nem um pouco envolvente. A jogabilidade não é fluída. A arte é ok, mas extremamente repetitiva. Os bugs são terríveis e impedem a progressão sem falhas. Não recomendo

If you can swallow the price, it's something to do for an evening but not much else.
Papers, Please в научно фантастическом стиле. Проверка документов упрощена, но присутствуют разнообразные дополнительные механики. Довольно короткая с упором на реиграбельность. Середнячок.
As someone who loves Papers Please and games like that, I was really excited for this game. And it didn't disappoint. It is very similar to Papers Please, but with a lot more things to keep track of and more systems to pay attention to. It might be overwhelming to some, but I found it to be just enough to keep my brain working without causing headaches. The rules changing every day is a really cool idea and it keeps you on your toes. But sometimes, it made it a little annoying because I would let someone in based on the previous day's rules. Otherwise, I would definitely recommend this to anyone else who loves these types of games.

l like the funny blue dog
Really fun game! The gameplay is very interesting and enjoyable. I really like playing it and spending time in the game. Definitely recommend it! 👍
入国審査のかわりに、映画「メン・イン・ブラック」風の世界観。 バッドエンドしないと辞め時を見失う、底なしの作業ゲー (マウスだけで操作可能なので純粋な作業ゲーが味わえる) ※内容はバカゲー要素の薄いシリアス寄り。
