Glory to Arstotzka! After winning a state-organised lottery, you now have a job at a border checkpoint, where your job is to examine immigrants' passports and travel documents, and decide whether to give them entry into your closely guarded, authoritarian state. Wielding nothing but the almighty stamp and a number of tools, you must fight forged documents, potential terrorists, and other sorts looking to slip under your gaze.
Papers, Please is a unique simulation of what it is like to man a border checkpoint and process immigrants, sifting through documents, consulting handbooks. The slightest mistake could have grave repercussions, not only for your country, but for your very family.
