From publisher blurb:
You've undoubtedly heard of the tabletop RPG MurderHobos, a fantasy tabletop RPG that lets you get all that "moral quandary" crap out of the way and just lets you murder monsters.
You'll need some monsters to kill, and that's where Murderous Monsters comes in. This book includes 16 classic creature types, from Giant Ants to Living Cysts and Gibbering Mouths to Vampires, each with representative art. Each creature averages 2 variants, so there are a total of 32 statted-out creatures here.
Even better, the book includes a chart of creatures by level and one consolidated list of every creature ability listed in the book, making it easy for you to create your own monster.
