Super Zombie Factory

When an ordinary man stumbles upon a mysterious factory that can manufacture an army of powerful zombies, his life splits between two worlds. In the modern era, he wields unimaginable power from the shadows. In the apocalypse, he reigns supreme as the undisputed master of the undead. With legions of enhanced zombies at his command, no force—human or otherwise—can stand against his rising empire across parallel realities.
