Publisher's blurb: The Umerican Survival Guide A Gonzo Post-Apocalyptic Campaign Setting and Sourcebook based on the articles of Crawling Under A Broken Moon. Foretold in the ancient calendars, early in the 21st century a rogue object from deep space hurtled near the Earth and struck the Moon. Its impact caused catastrophic destruction around the globe, ripping the very fabric of time and space itself; yet mankind still survived. Centuries later, the planet is reborn... a strange new place of alien wonder and death: a world ruled by savagery, cruel sorcery, and twisted science. Now is the time for the mighty to rise up and take their place in this perilous and untamed land. Will they bring justice or suffering? Only time will tell... User summary: The product is offered with two covers - "Chase" and "Delve". The contents are otherwise identical.
