Martian Crawl Classics

From the publisher:

Martian Crawl Classics is a sourcebook for the Mutant Crawl Classics role-playing game from Goodman Games that asks, "What if H.G. Wells’ War of the Worlds was the cause of MCC's Great Disaster?" This sourcebook runs with this premise, positing the the Martian invasion decimated mankind before the invaders died off due to susceptibility to Earth's bacteria. What would the remnants of society be like? What kind of twisted mutations would arise from exposure to the invader's Black Smoke and Red Weed? Do the Martian war machines still function? And did the Martians truly die off -- or are they merely hiding until the time is right for the Second Invasion?
