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.

유저 한글화가 있어서 해보았습니다. 여러분기가 있지만 분기를 보는 방법이 여러 자원 중 하나를 먼저 집중해서 모으기 식이라 플레이 과정에 잘 녹아있지 않았습니다.

這遊戲有點像有點克蘇魯風的請出示文件.遊戲沒有像請出示文件那樣有很多糾結的地方.不過遊戲畫質還不錯.目前剛玩完第一周目正在開發其他路線(小劇透一點遊戲有多種路線破關,可能有多種結局).由於遊戲才剛發行沒多久,目前開發商還在優化當中,也許未來也還會有一定的新內容加入.我個人認為目前特價的價錢還算划算,如果對於請出示文件或客蘇魯風有興趣的買下來玩幾個小時也不算太虧.
Great game!
遊戲玩法沒什麼問題,但是內容引導不足,像過關後說可以開分支但是分支玩半天還是走一樣的結局 各種研究到底要研究出什麼也沒說明只能一個一個試,每天的報紙還以為跟故事主線有什麼關係結果完全無關? 主角像個無情的檢驗機器然後研究一完成直接按下全部殲滅按鈕,但由於缺乏引導讓我搞不懂這是正確結局還是我有什麼沒做對的地方,當然如果通通不考慮劇情只玩檢測那這5小時也算玩得挺開心的
Как же я угораю с комментов людей, которые не могут в обычную логику! Игра всё объясняет, но находятся те, кто просто не читает. Мне всё зашло, в это интересно играть, на это приятно смотреть. Просто респект разработчикам, крепитесь, хороших вам отзывов.
I really like Papers Please. I *love* Security 51. I find the emphasis on examining people rather than documents to be much more fun. It’s brighter, it’s more colorful, it’s Men In Black silly (but also dark). This is very much my ♥♥♥♥. Great on Steam Deck with touch controls! I was pleasantly surprised!
It's fun! (Not fun enough to play for nearly 62 hours as my stats suggest, but I have a habit of forgetting to exit out of games when I shut my laptop.) That being said, it's certainly not [i] Papers, Please; [/i] to anyone hoping to play a similar game, I suggest looking elsewhere.
