Zombie TrainAuthor : Box10 - 19 063 plays
In Zombie Train, the aim is to protect a train and survive an invasion of crazed zombies. Dozens of zombies get on at each station to try and kill you. Start off with nothing but a simple pistol, but buy new weapons and objects as you go (the shop must be in the dining car, right?). Erect barricades to protect the windows and slow the zombies down, and use health potions when the situation gets critical.
