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

Author:Kristen Update:May 07,2025

The modding community for Warhammer 40,000: Space Marine 2 has been thriving since the game's record-breaking release last year, and their latest achievement is nothing short of groundbreaking. Tom, known as Warhammer Workshop and the mastermind behind the acclaimed Astartes Overhaul mod, recently unveiled a 12-player co-op mode, showcasing gameplay footage where multiple players take on a Tyranid Trygon Prime in what feels like an MMO boss fight.

PlayThis development is particularly remarkable because the vanilla version of *Space Marine 2* only supports up to three-player co-op. The modding team, with the backing of developer Saber Interactive, has not only shattered this limit but also set their sights on elevating the game even further.

In an interview with IGN, Tom expressed his awe at Saber'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 mod is still in the testing phase, yet it functions impressively well. The addition of 12-player co-op significantly alters the PvE balance, as the game's encounters were designed for fewer players. However, this breakthrough has spurred the modding community to develop new modes such as prop hunt, PvP within operations, expansive horde mode updates in anticipation of the official release, and thrilling raid-style missions with formidable bosses and innovative mechanics.

The Space Marine 2 modding community has grown substantially, with around 20,000 members actively participating in the main Discord server. Tom shared his enthusiasm, stating, "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."

With the 12-player co-op mod, fans are left wondering if this could hint at what's to come with Space Marine 3. The excitement around Space Marine 2 continues to build with upcoming features like the horde mode, a new class, and additional Operations maps and weapons. Saber Interactive has detailed Patch 8, provided insights into the horde mode mechanics, and introduced the setting for the new map.

Given the success of Space Marine 2, it's no surprise that Space Marine 3 is already in development. The announcement for the sequel promised "large-scale battles that are even more spectacular," which aligns well with the idea of expanding co-op player limits. While we await further details on Space Marine 3, the modding community will undoubtedly keep Space Marine 2 fresh and engaging, as evidenced by this latest innovative mod.
