Infra is a first-person game about structural and infrastructural decay. The devs explain that Infra is "what we like to call a gun free exploration game. Instead of large explosions and powerful guns, you will rely on your cunning to survive puzzles in an incredibly detailed world." Furthermore: "Your tools are simple: the camera around your neck and the wits to navigate a virtual labyrinth of debris." In the video you can see the player studying the innards of collapsing building, and taking photos of the damage with his camera. The devs explain that the game is inspired by notorious documentary The Crumbling Of America, which details the extent to which parts of United States' infrastructure has been allowed to decay.
