from the Introduction:
You are reading Dead Cities, a simple, fast-play post-apocalyptic role-playing game set in 2072, thirty-five years after the majority of humanity was killed by a terrible plague. The players are survivors of that plague or their descendants trying to eke out a living, or, hopefully, rebuild their own pocket of civilization (or even their own empire) out of the vine-choked ruins of the old one.
Dead Cities is based on Chris Gonnerman's excellent The Simple Game System rules.
There are slight differences in character generation from the base game. This version of the rules offers an additional ability/disability pair, primitive-advanced, and has a system for the generation of mutations, vehicle rules, firearms, and other differences necessary to support the tropes of the post-apocalyptic genre.
