The Pariah Missouri RPG can be used with your system of choice, but includes chapters for Savage Worlds, FATE, and HERO systems.
According to Andres:
"It will have all the background, characters, NPCs, maps and campaigns needed to create a rich world. Think of it as a campaign book that will have everything the GM needs to add Pariah to whatever rule system they enjoy. Included will be stats for all the major characters and everything you need to play Pariah! Full-color with art on every page 8.5 x 11. Over 120 pages!"Check out the campaign's Kickstarter page for the full range of investor incentives, as well as a better taste of the supernatural world of the setting, examples of artwork and add-ons.
You can also read about the background to Pariah Missouri here on HeroPress, when I wrote about the Kickstarter to fund the initial volume of the saga, back in 2012.
