● Original system of mutations: being at the head of an army of bloodthirsty zombies is good. Being at the head of an army of mutant zombies is even better. You have an arsenal of mutations at your disposal to adapt to the enemy's defenses: create new, even more powerful types of zombies, each with unique powers and abilities to deploy your strategies.
● Combo System: Mutations are great, but wouldn't it be even more awesome to be able to combine them, just to know what your enemies are up to (literally)? And we'll see if they died of laughter, or something else...
● You are not alone in the world: having zombies is a bit like having a pet: it's nice, but you have to take care of them... Exactly, that's what they're for humans. Your zombies eat them when they're hungry, and occupy themselves by playing with their insides the rest of the time. Well, obviously, these selfish humans are not always cooperative and tend to arm themselves with something other than patience!
● Contamination: would you like others to share your vision? A larger horde perhaps? Rally humans to your cause! No need to give long speeches or throw them flowers. Nothing beats a good old bite in the neck (or elsewhere if you feel like it)!
● Destructible scenery: In times of zombie apocalypse, humans seem to spend their time playing hide and seek. But when the hunger for fresh flesh gnaws at you, you hardly have time for this kind of childishness. So harness the power of your horde to destroy their poor hiding places and invade their playground.
