... If It Doesn't Bleed, You've Got a Problem!
The Explorer's Society barely scratched the surface of the Weird West (tm) with the 1877 edition of Rascals, Varmints, & Critters. Unfortunately, the book never made it to the public. The Society, never one to give up on a challange, is taking another shot at it. This time, they've called in a few experts to help them with their research.
If you're lucky enough to get your hands a copy of these notes, you just might stand a chance against the horrors and abominations prowling the mountains, prairies, deserts, and even the waters of the Great Maze itself!
If you're a Marshal, you can reload your cartridge belt with a passel of new abominations as well as details on some legendary horrors, like Dracula, El Diablo Negro, Frankenstein, and Springheel Jack. Rascals, Varmints & Critters II also contains some optional rules for those times when heroes catch one of the more unpleasant ailments the Weird West has to offer - vampirism and lycanthropy!
This 128-page supplement for the Origins Award-winning Deadlands roleplaying game lets loose a whole stampede o' new critters on the Weird West. Hunting season is open!
