Nothing to Declare is now available on Steam.
In this airport security simulation, players take on the role of an airport security officer, weighing bags, scanning luggage with an x-ray, and questioning travelers for suspicious items - it strongly recalls “Papers, Please”, just wrapped in a friendlier, hand-drawn look instead of that game’s grim border post.
An airport security simulation where players weigh bags, scan luggage, question passengers, and search for prohibited items in a cozy, hand-drawn environment. The game invites players into a cozy, hand-drawn world where your job is to keep things safe, with just a sprinkle of suspicion. Players manage airport checkpoint duties, greet travelers, check documents, and make judgment calls about suspicious items through various mini-games.
Features include mini-games for weighing and scanning luggage, a dialogue system for passenger interviews, a performance grading system with earnings, and 22 Steam achievements.
On Linux, the game doesn’t run natively yet, but works through Proton (recommended: Proton-8). Nothing to Declare normally costs €9.75, with a 30% discount bringing it to €6.82 during the introductory offer through August 8.
