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

by Scarlett May 14,2025

Ever since its record-breaking release last year, the modding community for Warhammer 40,000: Space Marine 2 has been thriving, and their latest achievement is truly groundbreaking. Tom, known as Warhammer Workshop and the mastermind behind the renowned Space Marine 2’s Astartes Overhaul, has unveiled a remarkable 12-player co-op mod this week. The gameplay footage is nothing short of spectacular, showcasing multiple players tackling a Tyranid Trygon Prime in a battle that feels like a thrilling MMO boss encounter.

This development is particularly surprising because the vanilla version of Space Marine 2 only supports up to three-player co-op. However, with the backing of the game's developer, Saber Interactive, the modding team has not only surpassed this limit to achieve 12-player co-op but is also driven by ambitious plans to elevate the game to new heights.

“Honestly, I’m just kind of in awe of Saber’s support for the modding community,” Tom shared with 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.”

It's important to note that the current mod is still in a testing phase, albeit a successful one. The introduction of 12-player co-op inevitably disrupts the game's PvE balance, as it was originally designed for fewer players facing off against the Tyranids and the Thousand Sons.

With 12-player co-op now a reality, modders are eagerly developing new add-ons to maximize its potential. Tom revealed to IGN that the team is crafting various modes, including prop hunt, PvP within operations, massive updates for the forthcoming official horde mode, and most intriguingly, raid-style missions featuring formidable bosses that require robust teamwork and innovative mechanics to defeat.

The modding scene for Space Marine 2 has blossomed into a vibrant community, boasting around 20,000 active members in the main Discord server.

“As both a modder and a player, it’s hard not to be excited,” Tom added. “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.”

Could this 12-player co-op mod hint at what we might see in Space Marine 3? The future looks bright for Space Marine 2, with the eagerly anticipated horde mode on the horizon, a new class in development, and additional Operations maps and weapons in the pipeline. Saber Interactive has recently outlined Patch 8, confirmed some horde mode features, and unveiled the setting for the new map.

Space Marine 3 is officially in development, a move that comes as no surprise given the phenomenal success of its predecessor. The announcement for Space Marine 3 promised "large-scale battles that are even more spectacular," which could suggest an increased co-op player count, similar to what we're seeing with the mod.

While we await more details on the sequel, the modding community will continue to keep Space Marine 2 fresh and engaging. This latest mod is a prime example of their innovative spirit and dedication.
