Necromunda is a skirmish tabletop war game produced by Games Workshop since 1995. It has been relaunched as Necromunda: Underhive in 2017. In Necromunda, players control rival gangs battling each other in the Underhive, a place of anarchy and violence in the depths below the Hive City. As in its parent game Warhammer 40,000, Necromunda uses 28 mm miniatures and terrain (in this case, the Underhive – a heavily polluted, underground industrial environment). Necromunda allows players to develop their gangs between battles, gaining experience, gaining and losing new members or equipment, according to a set of rules. Gangs that frequently win games acquire more credits (money) and fewer injuries and so are able to grow throughout a campaign.
