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

Author : Charlotte May 07,2025

Since the record-breaking release of Warhammer 40,000: Space Marine 2 last year, the modding community has been pushing boundaries, and their latest achievement is nothing short of spectacular. Tom, known as Warhammer Workshop, the mastermind behind the acclaimed Space Marine 2’s Astartes Overhaul, has recently unveiled a groundbreaking 12-player co-op mode. The gameplay footage is thrilling, showcasing multiple players tackling a formidable Tyranid Trygon Prime, reminiscent of an epic MMO boss encounter.

This development is especially surprising because the original game only supports up to three-player co-op. Yet, with the backing of developer Saber Interactive, the modding team has not only shattered this limit but is also aiming to enhance the game even further. Tom expressed his amazement at Saber’s support, stating to IGN, "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."

The current mod is a test version that, while functional, disrupts the PvE balance due to the increased number of players. However, this hasn't stopped modders from expanding on this new feature. Tom shared that the team is developing additional modes such as prop hunt, PvP within operations, and "massive" updates to the forthcoming official horde mode. The most anticipated addition might be raid-style missions featuring powerful bosses and innovative mechanics that demand true teamwork.

The Space Marine 2 modding community has blossomed, with around 20,000 members actively participating in the main Discord server. Tom reflected on the vibrant community, saying, "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 introduction of the 12-player co-op mod, fans are buzzing about what this could mean for the future of the series. Could it be a preview of what to expect from Space Marine 3? The excitement is palpable, especially with the upcoming horde mode, a new class, and more Operations maps and weapons on the horizon. Saber has recently detailed Patch 8, shared insights on horde mode mechanics, and revealed the new map.

It's also confirmed that Space Marine 3 is officially in development, which comes as no surprise given the success of its predecessor. The announcement of Space Marine 3 promised "large-scale battles that are even more spectacular," hinting at possibly increasing the co-op player count. Until we get more details, the modding community will continue to innovate and keep the game fresh and exciting, as exemplified by this latest mod.
