Zombies are soulless creatures, essentially dead, that can be controlled, as in Tower Defense: Zombies. Some force turned zombies into an army and sent them to storm your positions. They must capture some territory, and your task is to prevent the villains from reaching their goal, destroying them along the way. To do this, you must buy and place shooting turrets along the road; they will point their guns and fire automatically after installation. The choice of guns and their location depend on the vases. In addition, you can combine two identical weapons to get a more powerful one that kills zombies. This is important because the undead get stronger in Tower Defense: Zombies.
