Brothers, the fight is not over in Warhammer 40,000: Space Marine 2. During the 2025 Warhammer Skulls showcase, publisher Focus Entertainment and developer Saber Interactive revealed an upcoming new mode: Siege.
Siege mode is another PVE multiplayer mode for Space Marine 2. Set on Kadaku, you and two brothers must survive an endless wave of Tyranid and Chaos enemies, to your death.
The team accrues points after each wave, to be used on buying ammo, equipment charges and medical stimms, as well as game-changing summons including AI Space Marines as reinforcements, or call in a Dreadnought.
This will be a free update available for all, launching on June 26 as part of the Siege update. On PC (Steam), players can give this mode a try ahead of release via the Public Test Server, starting June 4.
Space Marine 2 already has some good horde-shooting gameplay, and this mode should really highlight the bigness of its hordes, as you attempt to survive the impossible.
For those who purchase the Ultra Edition, Gold Edition or the Season Pass, two cosmetic DLCs are coming featuring two more chapters of the Adaptes Astartes: The White Scars and the Blood Angels.
Space Marine 2 is out now on PS5, PC and Xbox Series X|S. Check out our review of the game here.
