Space Marines, prepare for new orders. Focus Entertainment and Saber Interactive have outlined the latest update for Warhammer 40,000: Space Marine 2, set to deploy on June 26. Announced during the annual Skulls Festival livestream, the “Siege” update brings with it an endless cooperative PvE mode and two chapter-inspired cosmetic packs, expanding both gameplay and customization for newcomers and veterans alike.

The headline feature is “Siege Mode,” an endless, three-player co-op experience. Here, squads defend an Imperial fortress on the war-torn planet Kadaku, facing relentless waves of Tyranids and Chaos adversaries. In gaming terms, PvE (Player vs Environment) means you’ll be squaring off against AI-controlled enemies, rather than other players. Each wave intensifies, demanding teamwork and quick adaptation to survive.
For those unfamiliar, the Public Test Server (PTS) offers early access to in-development content, allowing PC players to try Siege Mode starting June 4 and provide feedback—often leading to gameplay tweaks before the full release. One developer commented, “Community feedback on the PTS is key to refining our co-op experience,” emphasizing the collaborative approach to improvements.

Customization expands with two new chapter-themed DLC packs. The White Scars Chapter Pack features the Assault Champion skin, unique weapon skins for the Occulus Bolt Carbine, Stalker Bolt Rifle, and Combat Knife, plus fresh heraldry for White Scars and their Successor Chapters. The Blood Angels Cosmetic Pack adds distinctive armor and insignia tied to eight Blood Angels successor chapters. Both packs are available to those with the Season Pass, Gold, or Ultra Editions of the game. For those new to the game, the Season Pass is a one-time purchase that unlocks current and future downloadable content at a discount.
The announcement has sparked discussion across forums, with many players praising the addition of an endless PvE option—citing its potential for replayability. Saber Interactive’s ongoing engagement and free content updates continue to strengthen Space Marine 2’s standing among co-op shooters.
With Skulls Festival discounts live and a major update on the way, now’s an opportune moment for both seasoned Space Marines and newcomers to jump in. As the Siege begins, the challenge is clear: will your squad hold the fortress when the enemy never relents?
