Siege Assault Battle Group

Immerse yourself in the most intense battles of the Horus Heresy with the arrival of redesigned Cataphractii Terminators and Breacher Squads, purpose-built for vicious fighting in narrow corridors, boarding actions, and shattered fortifications. These iconic units—feared for their resilience and their ability to hold impossible positions—return with brand-new plastic kits. The Cataphractii Terminators have been fully rescaled to match the proportions of the new MkVI, MkIII, and MkII armour lines, while retaining their signature heavy plating and powerful protective fields, a reminder of an era where brute endurance mattered more than speed.
