The Zone is made up of a 30 km square area, that has wilderness, human camps, and a few heavily-guarded military bases. But, the game world is not one big world, but is a lot of smaller maps broken up by loading screens. Moving from one area of the Zone to another can only happen at certain passageways; a white fence border stops players from trying to cross the map in any other area. The game does not have vehicles that the player can drive. The player does have a fast sprint, but he or she cannot sprint without stopping, and the player can not fire weapons while sprinting
