The new codex represents the Chaos Space Marines in their ascendancy, allowing you to collect a force that reflects both your favourite units and Legions while remaining true to the background. Like Chapter Tactics, the Chaos Legions are getting new rules of their own to represent how they fight, as well as unique Stratagems, Warlord Traits and artefacts. You’ll be able to build powerful themed armies, from rebellious packs of Renegades to furious forces of World Eaters, and from terrifying battalions of Night Lords to the depraved duelists of the Emperor’s Children. There are 9 psychic powers too, as well as updated points costs, datasheets and much much more –
we’ll be taking a closer look at each Legion every day next week, starting tomorrow.
