Battle of Decay is a multiplayer open world survival horror game. You are a survivor of a disease, something you never saw before (you can find it out by playing single- or mutliplayer). You have to survive against Monsters / Mutants and you are able to craft, build, fight with or against other players. Find ways and loot to survive and hidden places with secrets.
A highway(Autobahn) is not a simple road where you can get faster from A to B, there are barriers, signs, road marks, intersections and also Roadhouses (Raststätten) where you can eat and park you car or truck. Battle of Decay will have a realistic map.
