Slitherine has officially launched the highly anticipated Warhammer 40,000: Battlesector - Ultramarines DLC for Warhammer 40,000: Battlesector during the 2026 Warhammer Skulls Festival.

The faction boasts a comprehensive toolkit designed to dominate both ranged and melee engagements. Leadership duties fall to the durable Captain in Gravis Armor, supported by the psychic prowess of the Primaris Librarian and vital battlefield healing from the Primaris Apothecary.

The infantry core relies on flexible Intercessors and heavy-hitting Hellblasters, while stealthy Eliminators and melt-wielding Eradicators handle specialized threats. For brute force, players can deploy Bladeguard Veterans, Terminators, and devastating armor like the Redemptor Dreadnought or the adaptable Gladiator Tank.

Coinciding with the Warhammer 40,000: Battlesector - Ultramarines DLC release, a massive free 1.0 update transforms the game's roguelite Crusade Mode, offering a revamped, randomized campaign structure perfect for testing the new faction's persistent army progression.
