In the shattered depths of Wisconsin and Illinois, survivors are besieged by the dead that have come back to life - Zombies! But not just any zombie...walking dead done Rifts-style! Zombies with minor Mega-Damage capabilities and the even more lethal Scrap Zombies re-engineered and rebuilt with M.D.C. armor bolted right onto their bodies and limbs, and turned into lethal weapons! Unless the source of this zombie plague can be uncovered and neutralized by NEMA defenders, North America may be overrun by the undead!
