The barge contains four areas, the cargo bay, the fuel room, the generator room and the side dock. There, the player can find more weapons, as well as more zombies waiting for the player.
Several boats can be found docked on the coastline, where players can use it to travel to a Unit 14 barge located roughly a mile from the island. Much of the fighting takes place on the beach, where several weapon wallbuys can be found around the place.
Players spawn on the coastline of an unnamed island, where several buildings can be found. Cargo is a unique map compared to the previous maps.
