A few months ago, White Dwarf published rules for using Chaos Cult Gangs in your games of Necromunda – and now we’re bringing you those rules absolutely free! They contain everything you need to start your own band of warp-worshipping malcontents, including gang, skills and equipment lists, six Wyrd powers, rules for using a Chaos Cult in campaigns, and a post-battle action that allows you to conduct a Dark Ritual and imbue one of your fighters with unholy power. There are even rules for using a Chaos Spawn… because if your Dark Ritual goes wrong you might find yourself down one fighter and up one terrifying lump of flesh and tentacles.
