The Experiment Zombie Apocalypse

This is what it looks like when the world ends. It didn’t start with a bomb. No army invaded. I’ve watched my classmates die or change before my eyes. I have seen whole swarms of them move around a person, cutting them with sharp claws or their teeth until they stopped moving. These, people, were once the Neo Humans, the ones who took Sapen's Golden Pill. But their enhanced bodies turned against them and all mankind.
Be ware, your world might be next...
