All mankind is forced into an endless wasteland migration game. Behind him is the 'shadow frenzy' advancing at a constant speed, devouring all living things. Everyone starts with only a simple mobile fortress (such as a crawler vehicle, mechanical spider, suspension cabin, etc.) And one life. Players must drive the fortress to escape in the endless wasteland, search for supply boxes, load new parts, upgrade the fortress, and at the same time deal with extreme weather, attacks by aberrant beasts, and the betrayal and plunder of the same kind.
