From Press Release:
New Game Update Brings Ever-Shifting Conflict to the 41st Millennium, a free new iconic Ork unit, and Domination game mode
The war for the contested worlds of the Imperium rages on. Following the strategic challenges of Planetary Conquest and the relentless pressure of Daemonic Incursion campaigns, a formidable new threat—and opportunity—arrives. Players will now face the endless, brutal calculus of the Crusade Mode.
Crusade Mode
A Roguelite Campaign of Endless War
In the grim darkness of the far future, there is only war. This new roguelite-style campaign ensures that “every game will be different from the last.” Players are called to choose a small battle-group from their favourite faction and launch a desperate crusade to reclaim the vital Imperial worlds of Baal and Chalnat, seeking to eradicate all opposing xenos and heretic factions. As the ancient maxim goes, “Even a man who has nothing can still offer his life.”
This game feature will challenge players to start with a basic army and fight their way through hordes of enemies, earning the opportunity to expand both their forces and firepower. The mode also introduces a new system to level up troops, with an experience system based on the ferocity of the battle, featuring a variety of ways to upgrade entire classes of troops.
Already available as a preview earlier this year, the mode has been further enhanced with critical balancing tweaks, new entry points on the planetary maps to unleash the Emperor’s righteous fury, and even new “planetary modifiers” that will dramatically affect all battles on that world.

New Free Unit for Ork players
The Iconic Kustom Boosta-blasta
Only in the mind of an Ork could such a magnificent, lethal machine be conceived. The Kustom Boosta-blasta is one of the deadliest and most notoriously unhinged vehicles in the Ork arsenal. Blisteringly fast and absurdly well-armed—after all, as the Orks know, “Red ones go fasta!”—it doesn’t just shoot things; it can literally set enemies on fire just by speeding past them with its back-mounted exhausts. Armed with a deadly turret-mounted Rivet Cannon, this speed-demon will tear clean holes through infantry and light armour alike. It is everything a Speed Freek dreams of in a vehicle, a screaming tribute to the unbridled WAAAGH!
(It requires the Ork Faction DLC to be usable in player’s armies)
“For Warhammer Day this year, we wanted to celebrate our ongoing commitment to expand and develop the Warhammer 40,000: Battlesector franchise. Whether through the Black Legion faction DLC, the launch of the complex and highly replayable Crusade Mode, or the dynamic addition of an iconic new unit like the Ork Kustom Boosta-blasta, our goal remains the same: to constantly further and improve the game.” — Marco Alessandro Minoli, Director of Publishing, Slitherine

Domination Game Mode
free for all players
Domination is a new game mode for Warhammer 40,000: Battlesector being added as part of a free update. It will be available to play in both Single Player and Multiplayer Skirmish, and will also feature as an objective within Crusade campaigns.
Domination tasks players with capturing and securing three areas spread across the center of each map. Each map features different locations to capture; some span entire loading bays, while others require the securing of a narrow corridor. Players earn points at the end of their turns for dominating each zone, which rewards aggressive play across the whole map and the elimination of enemy spearheads. To win, players will need to reach the target score threshold or completely eliminate the opposing forces.


The Forces of Chaos Arrive
To celebrate Warhammer Day 2025, Slitherine has announced the release of the next Faction DLC. A terrifying new Faction DLC is coming, as the infamous Black Legion will be available on PC, PlayStation, and Xbox from December 9th.
Once known as the Luna Wolves, they were one of the first 20 founding Legions of the Space Marines before turning traitor during the infamous Horus Heresy in the 31st Millennium. Led by the Warmaster of Chaos, Abaddon the Despoiler, the Black Legion stands as the primary antagonist of the 41st Millennium, a bitter foe that has waged the Long War for ten thousand years.
Now, this scourge of the galaxy will be available as a Faction DLC, ready to serve as a fierce opponent to all players of Warhammer 40,000: Battlesector. They follow the simple, cold truth of their corrupted existence: “Let the galaxy burn!”
Major Sales for Battlesector fans
Warammer 40,000: Battlesector franchise will be on sale from October 23rd to October 28th, with discounts up to 70%. Take the chance to grab your copy at a favorable price to celebrate the Warhammer Day 2025.

Releasing in 2021 on PC, PlayStation, and Xbox, Warhammer 40,000: Battlesector has received a positive reception from both critics and the broader community. The game currently has a ‘Very Positive’ rating from users on Steam.
Since its launch, Slitherine has continued to expand upon Battlesector by introducing several fan-favourite factions and the Dynamic Campaign. These include the Necrons, a mysterious race of robotic skeletal warriors, the bloodthirsty and ferocious Daemons of Khorne, and the Orks, who are characterized as being crude, aggressive and warlike.
