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.

If games like 'Thank You For Your Application', 'Papers Please', etc...You will love this! I'm enjoying how the rules change every day, instead of stacking on top of each other. Normal Mode is the perfect difficulty so far in my playthrough. Just hard enough to keep me focused, but still having lots of fun. Animations are funny and the pixel graphics are pretty cool. Music is also bumpin'.
Deberemos controlar la documentación de cada ingreso y egreso del área 51, incrementalmente irá subiendo la dificultad y cuando te das cuenta de ser un simple guardia de seguridad pasas a ser el médico, el psicólogo y hasta el héroe que debe salvar al mundo. Llegué al primer final...día 25 en mi lucha contra un grupo hacker que pirateó mis microchips antizombis, creé o contacté con una deidad todopoderosa que nos obliga a ir atras en el tiempo para resolver lo que hicimos mal... JUEGAZO, no me esperaba este desenlace... probalo, o velo acá👇🏻 https://www.youtube.com/watch?v=jZCdFNRCH74
Schönes spiel zum entspannen :D
Es un buen juego, el concepto está muy bien hecho, hay muchas cosas por analizar y la verdad, es algo que me gustó. La música, lo que te sale en el periódico cada día es muy divertido; si te gusta Papers Please, este juego también
świetnie sie gra, polecam
I have mixed feelings about this game, it is a good idea, a good twist of Papers, Please!, but in reality is just... Bland, mediocre at best. It has good mechanics every now and then, but overall, the experience is just not there. Let me compare it with Papers, Please! to illustrate it better... In Papers, Please! you have different mechanics in response of certain in-game events, for example, first you can cross the border with only your ID if you are from certain contry, next, you need a passport, but two days later there is an epidemic on another country so peolple from there needs a medical certificate that is valid for a certain period of time, then afterwards, the game changes the mechanic putting 2 or more documents in only one, later on, you have contraband, terrorist threats and so on, my point is, there is a story, simple, not too elaborated, but feels natural, goes with the flow of the game, and the aesthetic and the atmosphere are just great. Now, on Security 51, you have none of that, is just way too random, one day you must check internal organs, next day almost everybody gets a free pass, the idea of "Let everybody pass except...", "Ignore previous orders and call security if..." and "Ignore every order if..." are great ideas, but in this case it is just poorly implemented, what's going on the surface feels totally unrelated to the main story of your character, there is no correlation between the surface and the visitors you must check, some mechanics needs improvement, the microscope thing is just way too tedious. Security 51 has no real sense of urgency, there are no moral questions, there is not a single threat, I managed to lose a game because I deliberately stopped doing the surface missions, and speaking about the surface, after a couple of hours in game I realized you combat whatever is outside with certain resources, you get the resources doing missions, each mission costs your sanity, but you make enough to restore it after each shift, as well as your hunger, and you still manage to save up for the next upgrade, unlike Papers, Please! where you must choose if you are going hungry today so you can have an upgrade for your booth in 2 days, or wait longer. The gameplay is ok, the devs could add a story here and there, like one person trying to get inside tries to brive you to let him in, or how about having to correlate information clicking on it, so the computers prints a report that you must attach to the rejection like in Papers, Please!. (At this point this feels more like a Papers, Please! review) Do I recommend this game? Full price: No, over 50% discount: Maybe,
Played until floor 3. It really feels like they tried to add a lot of things but didn't do a good job of enmeshing them into one experience. The cell isolation and "city management" is depressingly boring. The story impetus of them shoving this all on you as a security guard holds no weight at all. If you liked papers please, you will probably find this game lacking. Every day has the normal paperwork issue, a "call the guards" issue, and a trump condition that ignores the others. So you check for the trump condition first, check for the guards condition, then pass them along if 6 numbers and a name match. Very simplistic, very repetitive. When there are overlaps (both conditions exist in blood test) then there's even less to do. The money management outside of work is also basically pointless. There are always distinct choices to get the most food/sanity for your money, basically no reason to mix and match. The upgrades are intended to make the tests easier/less time consuming, but on any given day you are NEVER under enough time pressure for it to matter. I could see myself enjoying it, but at this time the challenges for the player are too simple and the story is too bland.
