Doomsday Wasteland Mobile City Roaming Number

At the end of the 22nd century, the "Great Wasteland" era follows nuclear war and ecological collapse. The land is filled with toxic soil, mutated creatures and deadly radiation storms. Mobile city settings: "Ark-class" crawler city (such as the protagonist's city "Wanderer"): 8 kilometers long and 600 meters high, carrying the last gene pool of human civilization, migrating slowly across the wasteland at a speed of 5 meters per second. "Hunter-class" wheeled towns: fast, equipped with heavy artillery, and survive by plundering. "Drifter" single-person hovercar: The Lone Ranger's vehicle, flexible but fragile.
