Warhammer 40,000: Battlesector roadmap reveals new narrative DLC and faction content through 2027

Slitherine has shared an updated roadmap for Warhammer 40,000: Battlesector, confirming a new narrative DLC is in the works alongside additional faction content stretching into 2027.

The roadmap lays out four upcoming releases. A free update arrives in October, likely carrying more balance patches and quality-of-life improvements in line with what the game has received since launch. The new narrative DLC is slated for Q4 2026, following the same format as Deeds of the Fallen — the 12-mission Sisters of Battle campaign released earlier this year. After that, another free update is planned for Q1 2027, with a new faction DLC rounding things out in Q2 2027. No specific factions or story details have been announced yet.

Battlesector launched with a Blood Angels campaign pitting the gothic Space Marine chapter against the Tyranids, and for a while singleplayer story content was thin on the ground — subsequent DLC focused on adding factions for multiplayer and skirmish modes. Deeds of the Fallen broke that drought and clearly set a template Slitherine intends to keep following. The game has also grown substantially through free updates, adding the Daemonic Incursion and Planetary Supremacy modes, plus the roguelite Crusade mode, which just hit version 1.0.

There's no word yet on which faction gets the next narrative campaign — Astra Militarum is an obvious fan wishlist pick — but the roadmap signals Battlesector isn't slowing down anytime soon.
