Since its September 2024 launch, *Warhammer 40,000: Space Marine 2* has enjoyed consistent post-launch support, especially for its online multiplayer. Want to get a sneak peek at upcoming content? Here's how to join the public test server.
How to Join the *Warhammer 40,000: Space Marine 2* Public Test Server

Important Note: The public test server is currently only available on PC via Steam; it's not accessible on PlayStation 5 or Xbox Series X|S.
Accessing the server is straightforward for PC players. Simply locate *Warhammer 40,000: Space Marine 2* in your Steam library. The public test server will appear as a separate entry below the main game (provided you own the game on Steam). Download and install—it's a standalone build with its own files.
What's Included in the *Warhammer 40,000: Space Marine 2* Public Test Server?

The public test server features new PvE and PvP content, including new and modified weapons and customization options. The PvE side boasts a brand-new map, relaxed class restrictions on certain weapons, and updated online gameplay features. Remember, this content is a work in progress and subject to change before official release.
Online gameplay improvements include enhanced matchmaking for both PvE and PvP, focusing on balanced teams. PvE matchmaking aims to prevent teams from having too many players with the same class. A prestige leveling system is also included in PvE. PvP offers expanded lobby customization options.
Mods installed in your main *Space Marine 2* game will *not* work on the test server. While you can create and customize content using the test server's assets, this content will not be saved to your main game. Currently, there's no confirmation on whether progression or content from the test server will transfer to the main game; it's not expected.
