For ten thousand years, the Chaos Space Marines have waged near-constant war on the galaxy that cast them out. Once the defenders of humanity, the Heretic Astartes have pledged themselves to the Dark Gods. Led by maniacal leaders such as the fanatical Dark Apostle, bitter warbands of Chaos Space Marines roam the battlefield, armed with an array of vicious weapons. Barricades and defenders alike are torn asunder by the devastating heavy armaments wielded by Havocs – and the frenzied swipes of a lumbering Helbrute.
