This is a must have for owners of "The Mutant Epoch" RPG. Not only is it written for novice GMs but because it has so many plot ideas and pre-generated PCs it could be useful for experienced GMs as well. I personally find it useful because I've never GMed in a post-apocalyptic mutant setting and this book is a helpful tool in helping me understand how to do that. The town of Walsave and the mall are well fleshed out so this product is ready to play without much set-up. Just make sure the PCs have at least 2 characters each. The mutated post-apocalyptic future is brutal.
