Humanity around the world is randomly drawn into a "strange train" traveling in an endless abyss. Each player is assigned a separate 'box' (sanctuary). The game is divided into day and night: during the day, the train stops at different strange stations (infinite flow of copies, the scenes are never repeated), and players are encouraged to get off the train to explore and collect materials and rule fragments; at night, the train enters the fog, the danger level soars, and various weird aberrations will try to break in. Players must use materials to upgrade the box defense, make ghost props at the synthesis station, and survive to the end in a survival game full of backstabbing, calculations, and desperation.
