Like Zombies in Movies or TV Shows? Then this is a must have in my opinion. Rotworld gives you all the information you need to start a 'Zombie Apocalypse' campaign. Causes of the outbreak, the breakdown of society, pre & post hierarchy, even some maps of useful locations. Rotworld uses the same Pacesetter/ Goblinoid Games system that covers Cryptworld, Timemaster & Majus, allowing you a vast array of source material. Its a great book on its own, add any or all of the other titles & just about any campaign, from any time, can be built.
