Zombie Train

In Zombie Train you are travelling in a train. The trains stops every now and then to make the zombies come in. A little bit idiotic that zombies can break the windows of the train, but they do not shatter even if you shoot them. What the hell The game is still good and played from a birds eye view. Use W, A, S, D to move, space bar to get into the shop and the mouse to shoot. Use F to replace the window again.
