A dark mirror of the Emperor’s Space Marines, Heretic Astartes are the remnants of the forces that allied with the Warmaster in the Horus Heresy, mixed with more modern renegades. Millennia living in the warp has twisted them and granted them dark power that they use to strike back at their foes. A Lord Discordant leads a Hellforged Warband from atop a powerful Helstalker, commanding an arachnoid Venomcrawler, two Obliterators, who transform to manifest a variety of heavy ordnance, and five Havocs, who train powerful weapons on their foes.

A unit of 10 Legionaries act as a dependable and flexible core for these specialised units to act around, and a Chaos Rhino provides them with armoured conveyance across the battlefield. This box also contains two Chaos Space Marine transfer sheets.
