From publisher blurb:
A gonzo post-apocalyptic monster book for Umerica or other weird realms.
The wild and weird world of Umerica is a dangerous place filled with murderous creatures. It’s a good thing too since XP does not grow on trees! Within these pages dwell a cornucopia of crafty creatures to cram your campaign with consternation and paralyze your party with panic. Each one listed with adventure hooks to help drop them into your game.
Besides over 100 brutal beasts, this book also contains a bevy of barbarous Bosses based on a few of the creatures within. Each one listed with a backstory,common followers, motivations, and more.
The icing on the irradiated cake is the Scenario Sketches, a bunch of rough encounter ideas incorporating one or more of the monsters from this tome, all ready to be polished a bit and dropped into your campaign on short notice.
