Zombie Train is a top-down zombie defense game similar to the SAS: Zombie Assault series. The game takes place on a train that is being attacked by zombies, and your goal is to survive until the train reaches safety. Scroll through your weapons and kill the zombies before they break in and attack you. Repair damaged windows/barricades to ensure that no zombies board the train. Killing zombies will give you money, which can be spent on new weapons and improved barricades.
