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.

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.

За столько лет существования, алавар хоть одну нормальную игру сделает или так и продолжит хернёй заниматься..... и это, вы там пиндосам привет передовайте из академгородка, релоканты куевы.
Security 51 is a really great narrative-driven sci-fi vocation sim set in the infamous Area 51. Fantastic pixel art and excellent use of humor help elevate it from a pretty cool game to a genuinely great one. That being said, the tutorials and controls can be somewhat vague and unintuitive which can make onboarding feel frustrating. Although the ever-increasing load of responsibilities dumped onto our poor, hapless security guard protagonist may seem like a lot for some players, the game is careful not to overwhelm you with a myriad of mechanics all at once. Instead, it selectively introduces one or two mechanics for the player to focus on during a single shift rather than haplessly stacking them on top of one another during the earlier parts of the game. (That comes later!) Overall, I found this to be a standout entry in the vocation-sim genre and a lot of fun to play. While the lack of clear guidance, unintuitive controls, and inability to access the tutorial without starting a new game made returning after a long hiatus rather tedious, the strengths of the narrative and gameplay mechanics ultimately outweigh the weaknesses.

Great game. If you like Papers, Please, you'll enjoy this. It's Papers,Please + X-Files.
Fun. papers please but area 51 with slightly more replayability and fun things to check for. solving a desease with a fungus that causes a zombie apocalyse that you fix with tech that accidentally causes some cyberpunk style problem you gotta fix is one hell of a ride though, and thats just one of 9 possible variations i suspect the game has.
runs perfect on Steam Deck! a worthy successor of Paper, Please.
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。
Esse jogo é estilo Papers Please, só que tem mais recursos pra utilizar, muito viciante e divertido! Vários finais diferentes e possibilidades. Jogo excelente!
I have now reached the first ending and I have to say that I am a bit dissapointed. While the gameplay of the game is a solid papers-please inspired affair, the way everything else is structured leaves me almost angry at the wasted potential of the cool setting and neat sprinkled ideas. Just when the game becomes a bit challenging and you begin to have a lot of different gameplay elements at your disposal, it pulls some multiverse ♥♥♥♥ and forces you to go back to earlier gamestates to explore branching alternative timelines. This idea is fine in concept, but these shifts rob you of your unlocks and unlocked gameplay elements. You are basically forcing experienced players who have reached the end to grind through the same easy mechanics as before, and for what? The entire story is carried by the theme and setting, there are no memorable characters, sideplots like in Papers Please or metagame like making sure your family survives. This problem is compounded by the game being very easy for anyone that was actually born with a frontal lobe. Speaking of frontal lobes, how did nobody do the math on the different food and sanity items? It is completely off and buying the most basic Sandwich and Coffee is mathematically the most efficient use of money, which is completely contrary to how price scaling consumables should work. But this is honestly the perfect example of what went wrong with the game, nobody sat down to THINK about stuff. I was hoping for this to be a synthesis between Papers Please and Not Tonight, but all I got is a glance at a squandered setting and a waste of cool ideas and some neat pixel art. These devs are on the right track, and I will always advocate for people to make more pixel games in this genre, but considering that Beholder 2 came out a year ago, the team at Alawar who made Security 51 was obviously either a inexperienced B team or under time crunch, as it becomes very clear nobody had the time or capacity to sit down and have a hard think about how the game is gonna come together in the end. I hope that they will re-visit this game concept in the future and learn from the feedback given to them, as it stands I think the game is a okay 4 hour romp, and could be a lot more if you REALLY gel with the gameplay and actually want to grind through the timelines/endings, but the amount of wasted potential and disappointment makes me want to not recommend it.
I thought this was going to be a simple security guard game, but it turns out you can play through multiple times and get different endings. It's much more interesting than I expected. Unlike Papers, Please, where you build relationships with people and shape their stories, this game focuses more on the threat facing the world. So it doesn't have as much personal drama, but it's still fascinating to watch how the world and the visitors change over time.
