The ash wastes of Necromunda are an unforgiving environment, utterly deadly for those who can't take shelter from the toxic storms and rabid fauna. Gangs that operate in the Great Equatorial Wastes, and the Ash Waste Nomads who call them home, use Thatos Pattern Hab Modules for protection and communication. The largest of these structures are the Extended Hab Modules, which are often claimed by the most important gang members and reserved as a base of operations.

Necromunda is a world of mines, factories, refineries, and processing plants. The planet is a vast powerhouse of industry, making thousands and thousands of different items for use throughout nearby planetary systems.

The underhive of Necromunda is a close and brutal place, where short-range gunflights take place as fighters dart between cover, and brutal melee combat is almost impossible to escape from.
