Necromunda

Necromunda was founded some 15,000 years ago as a mining and manufacturing colony. In the millennia since, mountains have been reduced to rubble for the ore within and seas have become oceans of chemical sludge. Billions live, work, fight, and die in huge cities known as hives, never seeing the light of day. In the world outside, gangs and nomadic tribes war endlessly for control of valuable trade routes across the irradiated Ash Wastes.
