Fallout PnP combines the computer games Fallout, Fallout 2 and Fallout: Tactics into a cohesive, playable rules set for table top RPG gaming. Players can take on the roles of any of the several humanoid, robotic, and canine 'races' one would expect to encounter in the Fallout universe in a post-apocalyptic America. From the book "Fallout is a post-nuclear RPG set sometime after the great nuclear conflict in the year 2077. 99% of humanity and a good deal of other life perished in the nuclear war. Of course, millions still survived, although some were altered beyond imagination." The most current, complete, version of the rules is 2.0. Previous versions do not reflect entirely new rule sets, but rather a gradual streamlining and inclusion of additional rules.
