The Golden Age of Science and human civilization is shattered with the return of magic and the Coming of the Rifts. Overnight, human civilization is toppled. Many major cities are wiped from the face of the Earth. Humanity struggles to survive against impossible odds and the demonic horrors, aliens and monsters emerging from the Rifts.

Now comes the first invasion from another world. Its army? The corpses of our own dead, deliberately reanimated to become an invasion force to conquer the living. A growing number are mechanized zombies – nightmarish creations with multiple body parts and armor and weapons bolted right onto their bodies. Unless stopped, they could wipe out all human life.
