A Post Apocalyptic Campaign Setting

Welcome to the Wastelands
A Broken World
Our grandparents lived in a world without fear, without hunger or thirst. A world of lush green prairies and fertile farming fields. A world of global communications, of electronics and nuclear produced electricity with an abundance of clean air and drinking water. But better yet, it was a world without zombies and mutant creatures. After the outbreak that began the apocalypse, the world slowly went into chaos as society was dying and laws vanished. Yet it was not enough, more devastation befell the world as unmanned nuclear power plants went into meltdown and radiation poisoned the lands around.
Now imagine a world, broken and devastated, devoid of most of it's living population, and full of hungry zombies who shamble around looking for flesh to tear into. Those that survived these events realized that the rules had now changed, and that what ever was needed in order to survive, had to be done sometimes without hesitation.
Many years after the initial outbreak, zombies still roam the land and flood the great cities of old, which now lie in ruins. The remaining survivors have adapted to their new lives and have begun to rebuild some sort of society. Naturally in order to rebuild a world we'll need plenty of resources and materials. So now, many of us venture into the great old ruined cities of old, looking for valuable materials to salvage and trade for goods in Bartertown.
