Yes, and all the way through the previous 2 games to get back to the cars that were left on the road to get to this point. It means working BACKWARDS through the previous 2 maps with ALL the zombies on it that were not killed on the way here. Each map will be a new game ( just as it was going forward, except for the equipment that was left at the other end of the teleporter and all your clothes). Of course, we want to complete this map before going back.
