This game is probably one of the best games I have played on steam. It is a highly realistic zombie game. Everything from getting a cut because you jumped over a fence or walking cause your car broke down. Its just so much fun man. The interesting part is that there is no real ending to the game as far as I know. It even says that "this is how you died" when you first start a new run. Also the map is massive and there is plenty of places to go and explore. Me and a friend went to one the the major city's yesterday and it took us 3 hours irl to get there in a car.
