Saber Unveils Warhammer 40K: Space Marine 2 Siege Mode & DLC

Warhammer 40,000: Space Marine 2 has officially announced Siege mode—its innovative twist on the classic Horde experience. Alongside the debut teaser trailer and screenshots, developers shared key details about gameplay mechanics. As an avid Warhammer 40,000 enthusiast and Space Marine 2 follower, I sought deeper insights—so I reached out to Tim Willits, Chief Creative Officer at Saber Interactive, with pressing questions. His responses offered fascinating revelations.

Siege Mode: Tactical Carnage Meets Endless Swarms

In addition to breaking down Siege mode's core mechanics, Willits confirmed players can summon devastating Dreadnoughts during battles and explained why Space Marine 2 caps co-op at three players. Our discussion also touched on the game's long-term roadmap, confirming additional content planned beyond the first year. Below, we unpack everything revealed about Space Marine 2's Siege mode and future updates.

Why Three-Player Co-Op?

Willits emphasized Saber Interactive's focus on balancing intensity with strategic teamwork—smaller squads amplify coordination while maintaining the game's signature high-octane combat pace.

The mode introduces escalating enemy waves, rewarding players who master tactical positioning and ability synergies. Completing objectives unlocks powerful reinforcements, including the aforementioned Dreadnought—a game-changing asset against overwhelming odds.

Beyond Launch: A Living Battlefield

While Siege mode launches with structured waves and environmental hazards, Willits hinted at dynamic enemy behaviors and randomized events in future updates. Expect faction-specific modifiers and progression systems tied to Warhammer 40,000 lore.

Pre-order bonuses include exclusive cosmetic upgrades for Siege mode, with post-launch expansions introducing new maps, enemies, and weapon loadouts. Further details will emerge closer to Space Marine 2's September release.
