Warhammer 40,000: Space Marine 2
Space Marine 2 Steam Workshop and 10-player co-op guide
Patch 14 opens official Steam Workshop support, but a Workshop listing does not make every mod suitable for public matchmaking. Expanded 10-player co-op is a modded experience, not the standard official lobby size.
Safe mod routine#
- Subscribe through the game's official Steam Workshop.
- Read required dependencies and supported patch version.
- Back up local configuration and saves.
- Test one mod in a private session.
- Make sure every participant uses the same mod set and version.
Disable gameplay-changing mods before entering standard matchmaking unless official guidance explicitly permits them. After a game patch, wait for the mod author to confirm compatibility rather than repeatedly loading an important save.
10-player co-op#
Larger groups add network, CPU and encounter-script load. Use a private lobby, identify the host, and expect missions or cinematics authored for the normal party size to behave unexpectedly. If the lobby fails, test the same group without mods before blaming the server.
