APOCalypse 2500 RPG Game masters can utilize the theories and unique twists on what zombification is in this book to tailor the various flesh-eating monsters to suit any game scenario or plot element. I have gone into some depth as to the behavior of both zombies and the plague as well as how it mutates and what it really is. This book has become far more than a single monster reference as it creates a complete resource and new reality within the world of APOCalypse 2500. Included in this volume is a complete zombie adventure scenario set in an abandon walled city, lost to the plague centuries ago.
