Evaluation

Warhammer 40,000: Battlesector launched on July 22, 2021 and has maintained an exceptionally consistent post-launch content cadence. Since launch, the game has received major faction DLCs and narrative content at a steady pace: Tyranid Elites Pack (December 2021), Blood Angels Elites Pack (December 2021), Necrons Faction Pack (April 2022), Sisters of Battle (December 2022), Orks (May 2023), Daemons of Khorne (August 2023), T'au (February 2024), Astra Militarum (December 2024), Deeds of the Fallen narrative campaign (May 2025), Black Legion (February 2026), and Ultramarines (May 2026). The game also received a major free Crusade Mode update that graduated to its full 1.0 version alongside the Ultramarines DLC in May 2026. Most importantly, the developer posted a roadmap update on August 7, 2026 — just 11 days before today — explicitly confirming that both a new Narrative DLC and a next Playable Faction are in active development. The developer states they "remain committed to expanding the game with fresh narrative content, ongoing quality of life updates, and even more factions," and that they will share more details on the upcoming Narrative DLC and next Playable Faction as their release dates approach. This is a clear, direct statement of planned content from the developer. The game also received a patch on July 22, 2026 (the game's 5th anniversary), confirming the development team remains highly active. Players who prefer to wait until all content has shipped should hold off — at minimum one more narrative DLC and one more faction are confirmed as coming.

About this game

Age of Crimson Dawn

Experience an epic twenty mission single-player campaign that explores the aftermath of the Devasta-tion of Baal. Help Sergeant Carleon and his allies purge the Tyranid infestation on Baal Secundus, and preserve the honour of the noble Blood Angels.

Skirmish Mode

Fight across the surface of Baal on maps of your choosing in the Skirmish mode. Pick the faction you'll lead as well as the one you'll face. Completely customize your army list by selecting your units, heroes and their loadouts. It is available with three different types of Objective: Exterminatus, Conqueror and Strategic Command.

Planetary Supremacy Mode

Planetary Supremacy is a conquest-style skirmish campaign, introduced in a free update as part of our ever expanding plan for Battlesector, in which you, the player, decide the outcome.

Take command of your favourite faction and conquer the planet in a series of procedurally generated skirmish battles. To achieve victory, capture more tiles, acquire strategic resources and expand your army. Then, bring destruction to your enemies in Skirmish battles.

Daemonic Incursion

Daemonic Incursion is a single-player mode that is available to all Battlesector players as part of a free update that was launched alongside the Sisters of Battle Faction Pack. In Daemonic Incursion, waves of Khornate daemons enter realspace to spill blood, collect skulls and overrun your forces. This is a last-stand mode, in which your objective is simple: SURVIVE!

Forge Your Armies

Command iconic units like the Sanguinary Priest, the Librarian Dreadnought, and the Hive Tyrant to annihilate your foes. Use over 60 abilities and 50 weapons to orchestrate your opponent’s bloody de-mise.

Build Momentum

Each faction has a unique Momentum system that can result in a Surged unit. Units that Surge are able to string together superhuman chains of actions, or use the opportunity to further upgrade their abili-ties.

Call In Air Support

Use Command Points to call in faction-specific air support abilities. The Blood Angels Stormraven can obliterate xenos with a missile barrage, or deep strike a unit of veteran Assault Marines behind enemy lines. Meanwhile, the Tyranid Harpy can devastate the enemy defenses with its Sonic Screech, or scat-ter the battlefield with its deadly Spore Mines.
