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.

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.
it is a pretty good game that has no blood despitye the video (as of my knoladgre

UN ESPECTACULO SOY BUENISIMA JUGANDO BESOS
Quite fun
Die ersten Stunden machen ja eigentlich Spaß, auch wenn es etwas zu repetitiv ist. Die kleinen "Nebenschauplätze" wie die Missionen in der Stadt oder die Isolationskammer haben aber gefühlt sehr wenig Einfluss auf den Verlauf des Spieles. Was ich aber wirklich Schade fand, und hier finde ich ist viel Potential verloren gegangen, ist der Verlauf der Spielmechanik. Was meine ich? Es werden immer wieder neue Mechaniken (UV-Licht, Blutabnahme, etc.) vorgestellt um aber leider im selben Zug alles was davor war zu ignorieren. So muss man im späteren Verlauf keine Organscans oder Ähnliches machen und die "Updates" die man sich vielleicht gekauft fühlen sich dann besonders unnötig an. Das Spiel ist bald einmal vorbei und lädt ein, weiter zu spielen und andere "Wege" einzuschlagen. Ich wüsste ehrlich nicht was oder an welcher Stelle des Spieles ich etwas anders machen sollte (außer vielleicht absichtlich etwas falsch machen) was den Verlauf so ändern würde, dass ich einen erneuten Durchlauf starten will. Lange Rede, kurzer Sinn... das Spiel wirkt auf mich persönlich etwas unfertig. Als hätte man einiges an Ideen gehabt, das Fundament zwar gelegt aber dann einfach nix daraus gemacht. Schade.
It's spin on papers please-like games is that is has a wide variety of checkable things, whilst only some are relevant on each specific day. It's quite fun
love this game!
