From publisher blurb:
The world has been destroyed, and civilization has collapsed, but not everything is rubble and ruin.
The southern tip of the former state of Illinois, about 330 miles or 500 kilometers south of downtown Chicago is a corridor of former farmland that was spared from the worst of the collapse. New states, representing the different forces in the Global war, occupy portions of a one hundred- and fifty-mile-long strip of agricultural land. And the center of that strip of land is the city state of Carbondale.
The book outlines the major factions, industries, and shops that can be found in Carbondale twenty years after the Global Wars.
The Free City of Carbondale complements the Chicago Ruins and provides information to allow GMs to run Rubble and Ruin games that focus on more than just rubble crawls. Several adventure seeds and new social Enhancements are included.
