All maps are spacious and almost empty until you reach the museum part which is the best of this campaign. There is a huge disadvantage for the panic events. Since all maps are spacious, the zombies will have hard time reaching the survivors. The second map with gassing the van with 6 gas cans are quite redundant. Why do you need 6 gas cans just for the van to move for like 5 meters? The finale has a good concept but only one tank present? The finale is also short as well and zombies have hard time spawning. Overall the campaign looks really good and at least fun to play.
