Necromunda was spun off from a previous attempt of Games Workshop to popularise a set of rules for low-key skirmish battles in a hive world setting. "White Dwarf" magazine published such a ruleset between autumn and winter 1990–91 dubbing it "Confrontation". It was set on the hive world of Necromunda but made no reference to houses and such, instead concentrating itself on the various types of gangs: clan warriors from the spires, brat 'poseurs' from the upper levels which went 'down' to experience the thrills of lowlife, undercity mutants, diseased scavengers from the toxic wastes and the Adeptus Arbites ever-ready to deal swift and summary "Judge Dredd"-like justice.
