However, they’ll be available in private lobbies for Operations, and Saber Interactive will share some tools to help modders.

Even after selling 4.5 million copies, Warhammer 40,000: Space Marine 2 is settling in for the long haul, with its next big update due in December. It brings a significant change for those using mods, prohibiting them from playing in public online sessions.

Explaining the situation, game director Dmitriy Grigorenko revealed that he’s happy to see what players can create with mods and game files were left unencrypted for this purpose. However, they’re also causing stability issues with servers and even affecting those who don’t use mods, corrupting their save files.

As a result, mod users can’t enter public sessions. The good news is they’re allowed in private lobbies for Operations and will apply to Eternal War once it receives custom matches. “We will continue to provide all necessary server infrastructure so you can play online with your friends with mods.”

Saber will also ensure “an easy entry point to our backend for games with mods installed, so modders won’t have to spend time hacking the executable after each patch.” It will also release some tools to help modders with development. There’s no ETA on this, so stay tuned for further updates.

Warhammer 40,000: Space Marine 2 is available for Xbox Series X/S, PS5, and PC.
