Accessing the server is straightforward for PC players via Steam. Simply locate Warhammer 40,000: Space Marine 2 in your Steam library.

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. The PvE side boasts a new map, relaxed class restrictions on some weapons, and altered online gameplay features. Remember, this content is a work in progress and subject to change before the official release.
Online gameplay improvements include enhanced matchmaking for both PvE and PvP, focusing on balanced teams. PvE matchmaking minimizes identical class selections on the same team and introduces a prestige leveling system. PvP offers expanded lobby customization.
Mods from the main game won't work on the test server. While you can create and customize content using the test server's assets, this progress won't transfer to the main game. Currently, there's no confirmation of whether progression or content will carry over.
