From publisher blurb:
Welcome to Mod Kit #1 for AZ: After Zombies! Using the material found in this book, plus that found in AZ, you will be able to run a robo-pocalypse, or for a real horror show, add murderous robots to your already existing zombie apocalypse.
Mod Kit #1 contains a brief set-up for one robo-pocalypse, along with discussions about running a game based around mechanical scarcity. The real heart of the book, though, are the 12 new robotic monsters, suitable for a variety of different campaigns where robots have toppled the world of their creators.
