How to Join the *Warhammer 40,000: Space Marine 2* Public Test Server

Important Note: The public test server is currently PC only. It's unavailable on PlayStation 5 or Xbox Series X|S. Accessing it is straightforward for PC players via Steam.
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. It's a separate download 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, weapons, and customization options. PvE receives the most significant updates, including a new map, relaxed class weapon restrictions, and online gameplay adjustments. Remember, this content is a work in progress and may change before official release.
Online gameplay improvements include enhanced matchmaking for both PvE and PvP, focusing on balanced teams. PvE matchmaking reduces the likelihood of players choosing the same class on the same team and introduces a prestige leveling system. PvP offers expanded lobby customization.
Existing Space Marine 2 mods will not work on the test server. While you can create and customize content using available assets, this progress will not transfer to the main game. There's currently no confirmation on whether progression or content will carry over from the test server to the main game; it's not expected.
