In Zombie Horde, you don't fight zombies... you control them! Play as an evil groundskeeper and build a horde of zombies as you attack the drunken fools in your cemetery. Kill humans and walk over their corpses to turn them into zombies, which will help you fight humans. There is a limit to the number of zombies you can have in your horde, but you will earn money for every corpse that you collect. This money will be used to purchase various upgrades, such as max units, health, and damage.
