When the walking corpses saw that their opponents were gaining momentum, they got angry because of the cowering feeling that had crept deep inside them. They snarled at them and decided to meet them even though they were afraid. Their instincts was telling them that these improved beings were not to be trifled with but the world on the other hand which dictated their existance didn't allow them to abort. Any of them which defected was peeled like a nut before their existance was erased. No one among them was ready for that torture as although these beings had no soul, that didn't mean that they can not feel pain. They were determined to go down with these survivors. It was at first, only a single walking corpse that initiated the fight and when the others saw that, their blood boiled from determination and just like that, they again scurried towards them in waves like maggots swimming in a pool of filth.
