Disclosure- I was sent a copy for review purposes.
This book, in short, is exactly what it purports to be: a toolbox for running adventures in the city of Meatlandia. Designed for use with the Lamentations of the Flame Princess rules, it is easily portable to other OSR systems. It is a collection of NPCs, spells, factions and classes pertaining to Meatlandia, a city ruled by warring factions of Carnomancers, or Meat Wizards. Highlights include details of the major NPCs that control sections of the city, a massive collection of spells that deal with meat magic, and a couple of bard subclasses that will easily fit into any gonzo style campaign. I personally plan to use Our Lady of Sorrows, the physical manifestation of the city's consciousness, the next time my players hit a wall- literally, the next time they strike a wall in a city they will meet her.
Another standout section is the detailed Magic in Meatlandia part, which details hiw meat magic works and what it entails. This area is rich to plunder and I can see myself setting up some meat wizards for later use. Also of interest is the Chaos DJ subclass- you gotta love a class that will resort to absolute destruction of everything in order to prove a point.
The spells section is good for PCs wanting to try out wacky flesh and bone manipulation techniques, and the bestiary, while limited, can easily be expanded on for some truly grotesque results! Magic items are cool (especially the Meat Shield!), and the hooks/rumours/game seeds sections are solid, though spread out over three sections of the book. Here is my major gripe- quite a bit of the book could be condensed and organized a bit better- hooks are in three.places, magic and magic classes are scattered, and the bestiary is broken up strangely. Another editing pass wouldn't hurt, either, but overall this is a fun book for a weird place that will fit into any gonzo campaign and would work nicely to give your players a curveball in a more straightforward campaign. Good work!
