Have-Not is the post-apocalyptic worldbook for the JAGS RPG. From the intro:
"Have-Not is all about rolling into a small dusty town in armed vehicles and laying the .30-cal smack-down on an evil sheriff. It's about getting your friends together and heading into the Denver Ruins to brave the death machines and the bio-horrors left over from the Age of War to bring back bounty from another era. It's about being an intelligent, telepathic Bengal Tiger with a cybernetic rocket launcher or Cyborg with a built in rocket launcher-or a mobile telepathic plant-or maybe just a human, gun slinging bad-ass.
"Have-Not is about exploring a world that's been touched by a miraculous technology (controlled by the Haves, who are now gone) and then abandoned. It's about setting things right or seeing what's broken or just getting rich and powerful-or any of those things. It's about a world that's complex, that's got a lot going on, and has secrets to discover."
