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.

Отличная игра. Расслабляющий геймплей без напряга. Музыка хорошая.
The game itself exhibits abnormal quantity of mechanics. However, being already on level three, shows that in comparison to the plot-based games in this genre (like papers please) this game lack freedom in choice and personal interest contamination to the process (like in beholder from the same developer and mentioned paper please). This is funny and time-killing game for routine work simulator, but no rule breaking incentive or personal choice influence is not introduced. This is not directly the disadvantage itself, but if plot and setting were as powerful as mechanics, the game could be one of the best!

Un superbe Papers Please like avec pleins de mécaniques de gameplay et de fins alternatives. Encore une bombe d'Alawar! (I need a mobile version!!!!)
it was ok. just not what i expected. i imagine others would enjoy this if they enjoyed that zombie one too.
paper please
看了下评分一般,但是对于《请出示证件》的平替,我觉得很好了~·但是我为什么老卡在25关!!!!
I played Papers, Please. And while I am only a few hours into Security 51, I don't have anything super negative to say about it, but I do have some criticisms. It's a wackier, more whimsical and casual version of its inspiration from what I'm gathering so far. The gameplay can become repetitive, but I don't necessarily think that's bad. It's far more casual and laid back. Rather than pile on more things to look at for each stage, you're looking for different things with each person. Personally I enjoyed that aspect because I was treating Papers, Please like a real job LOL. Had me stressed, so this was a nice change. There is a lack of story or greater objective outside of finding the "cure" or solution to what is happening on the outside. This part is whatever. It moves it along but frankly could be expanded on. Cool idea, but would love to see what more could be done there. Additionally, I like the isolation chamber. Gives you something else to do or pay attention to. There is also a lack of characters to engage with and doesn't have the same underlying plots driving the main game. The dialogue is recycled for each character. I may have to go further, but I would like to see some more development especially early on to keep the engagement. I can agree with other negative reviews that the game does lack in this sense. The humor is cheeky and corny at times. I like this part, because like the game play, it's very unserious. I think the core mechanics of the game are there, but in terms of worldbuilding and story, there is much to be improved upon. It feels like the game sets you up for something really interesting with references to popular cryptids and more. You believe it's going to take you somewhere, but so far it's repetitive with only a meter bar (finding the "cure") to move you along. It's up to the devs as to whether they want to build the story on what themes they have which in my opinion is SOLID... But, it can also just be a casual version of Papers, Please with cryptic wacky themes for the fun of it. It's up to them I suppose. Frankly, I've had fun so far playing it, and I intend to fully finish the game. I find it relaxing, silly, and fun. If the devs decide to expand the story or make the narrative more engaging then I'll be hooked, but if they also decide to keep it where it is at, then it'll just be a goofy time killer I'll come back to. Also for how cheap it is, I would recommend trying it out. It's very cute. Creativity/Whimsy 8/10 Gameplay 6/10 Story 2/10 Overall Fun ~5/10
Занятная и забавная индюшатина в стиле Papers Please. Вполне подойдет для того, чтобы почилить пару десятков часов.
Mi è piaciuto questo giochino sulla falsa riga di paper please. In alcune meccaniche l'ho trovato più intuitivo e dritto al punto, nonostante la varietà di attività da effettuare alla scrivania. Bella progressione e storia interessante. Consigliato dato il prezzo onesto.
Definitely fun.
