"Warhammer 40k: Space Marine 2 Mod Adds 12-Player Co-Op, Raid Missions Coming"

by Joseph May 28,2025

The modding community for Warhammer 40,000: Space Marine 2 has been pushing boundaries ever since the game's phenomenal launch last year. The latest achievement from the modders is nothing short of revolutionary.

Tom, known online as Warhammer Workshop and the creative mind behind the acclaimed Astartes Overhaul mod, has recently unveiled a groundbreaking feature: 12-player co-op. This update is a game-changer, as showcased in gameplay footage where multiple players tackle a formidable Tyranid Trygon Prime, evoking the thrill of an MMO boss encounter.

PlayOriginally, **Space Marine 2** was limited to three-player co-op, but with the support of developer Saber Interactive, the modding team has shattered this limitation. Tom expressed his admiration for Saber's support, stating, "None of us expected 12-player PvE sessions to be possible this soon — but somehow, here we are. Thanks to their generosity and trust, this huge leap forward is finally here, and it completely changes what we can do."

It's important to note that the current 12-player co-op mod is still in the testing phase. While it functions well, it significantly alters the game's PvE balance, which is understandable given the increased number of players.

With 12-player co-op now a reality, modders are not stopping there. Tom shared with IGN that the team is developing additional modes such as prop hunt, PvP within operations, expansive updates for the upcoming official horde mode, and thrilling raid-style missions featuring formidable bosses and innovative mechanics.

The Space Marine 2 modding community has flourished, boasting over 20,000 active members on their main Discord server. Tom's enthusiasm is palpable, "As both a modder and a player, it’s hard not to be excited. Huge credit as always to the Saber team for not just making all this possible, but continuing to drop amazing content of their own too, without any of the usual predatory battle-pass nonsense we take for granted in modern titles."

This 12-player mod might offer a glimpse into what Space Marine 3 could bring to the table. The excitement around Space Marine 2 is palpable, with the imminent release of horde mode, a new class, additional Operations maps, and new weapons. Saber Interactive has detailed Patch 8, confirmed horde mode mechanics, and revealed the map setting.

With Space Marine 3 officially in development, expectations are high. The announcement promised "large-scale battles that are even more spectacular," hinting at potentially larger co-op player counts.

Until we get more details on the sequel, the modding community will continue to innovate and enhance Space Marine 2, as evidenced by this remarkable 12-player co-op mod.
