From Press Release:
The most infamous Chaos Space Marines have arrived in Warhammer 40,000: Battlesector with a brand-new faction DLC, introducing fifteen fearsome units that bring the wrath of the Warmaster. Originally born from the once proud Luna Wolves, one of the original sixteen founding Legions of the Space Marines, these warriors fell from grace during the Horus Heresy of the 31st Millennium and were reborn as the dreaded Black Legion.
Led by the feared Abaddon the Despoiler, the Sorcerers of Chaos, the Masters of Executions and the Cultist Firebrands, the faction offers a brutal arsenal. Chaos Terminators, Legionaries, Raptors, Chosen, and Havocs form the relentless backbone of the Black Legion’s armies, each contributing distinct tactical strengths. Supporting them are the terrifying Daemon Engines, whose power can unleash torment and savage destruction.
With this DLC, available on Steam, Xbox and PlayStation, players can embrace the unholy might of Chaos Undivided and experience a new level of strategic brutality in Battlesector.
The Black Legion stands ready and the galaxy will burn in their wake.

Warhammer 40,000: Battlesector so far
Warhammer 40,000: Battlesector is a fast-paced turn-based strategy game set in the grimdark universe of the 41st Millennium. This title is a beloved strategy supported not only by the community, but also by the developers and the publisher, Slitherine, which acquired the rights to the game’s engine in 2024.
More than a few major free updates and the new Crusade mode are a testament of the effort put into the game, alongside the long list of factions DLCs: from Orks, Necrons, T’au and Demons of Khorne, to Sisters of Battle and Astra Militarum.
The last DLC, Deed of the Fallen, is the first, but not last, feature DLC, where a 12-mission story campaign has welcomed enthusiast players to Warzone Chalnath.

To celebrate the new addition to Battlesector DLCs, the base game on Steam will be 60% off, while the faction expansions will be discounted by up to 30%. Furthermore, the first feature DLC, Deeds of the Fallen will be available at a 10% discount.
