"Warhammer 40k: Space Marine 2 Modders Enable 12-Player Co-Op, Plan Raid Missions"

Author : Sophia May 17,2025

The modding community for Warhammer 40,000: Space Marine 2 has been exceptionally active since the game's record-breaking release last year, but their latest achievement is nothing short of groundbreaking. Tom, known in the community as Warhammer Workshop and the creative force behind the acclaimed Astartes Overhaul mod, announced the release of a 12-player co-op mode this week, and the gameplay footage is nothing short of spectacular. It showcases multiple players engaging a Tyranid Trygon Prime in a battle that feels like an epic MMO boss fight.

PlayThis development was unexpected, as the vanilla version of Space Marine 2 only supports up to three-player co-op. However, with the support of developer Saber Interactive, the modding team has not only surpassed this limit but also set their sights on enhancing the game further.

Tom expressed his awe at Saber Interactive's support for the modding community, saying, "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 in a testing phase. While it functions well, it significantly alters the game's PvE balance, as it was originally designed for fewer players. This change has led to an influx of new modding projects aimed at maximizing the potential of 12-player co-op. Tom revealed that the team is developing various new modes, including prop hunt, PvP within operations, extensive updates for the upcoming official horde mode, and ambitious raid-style missions featuring formidable bosses and innovative mechanics that demand teamwork.

The Space Marine 2 modding community has grown impressively, boasting around 20,000 active members on its main Discord server. Tom emphasized the excitement within the community, stating, "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."

With the introduction of the 12-player co-op mod, speculation about Space Marine 3's features has begun to circulate. The upcoming sequel is already in development, and the success of Space Marine 2 suggests that larger-scale battles could be on the horizon. When Space Marine 3 was announced, the promise of "large-scale battles that are even more spectacular" hinted at an increased co-op player count.

As Space Marine 2 continues to evolve with the impending horde mode, new classes, additional Operations maps, and weapons, the latest patch (Patch 8) has provided more details on these exciting updates. Until Space Marine 3 reveals more about its gameplay, the modding community will keep pushing the boundaries of what's possible in Space Marine 2, as evidenced by this latest 12-player co-op mod.
