It's crucial to note that while *Warhammer 40K: Space Marine 2* is playable on PlayStation 5 and Xbox Series X|S, the public test server is exclusive to PC players. Accessing the server is straightforward for PC users via Steam.
PC players can easily join by searching for *Warhammer 40,000: Space Marine 2* in their Steam library. The public test server will appear as a separate title below the main game, but only if you've purchased *Space Marine 2* on Steam. Once located, download and install the test server, which operates as a standalone build, distinct from the main game.

The *Warhammer 40K: Space Marine 2* public test server introduces new content for both PvE and PvP modes, including new and modified weapons and customization options. The bulk of the updates are in PvE mode, featuring a new map, relaxed class restrictions on weapons, and modifications to online gameplay features. Keep in mind, these additions are still in development and may evolve before their official release.
In terms of online gameplay, the test server enhances matchmaking for both PvE and PvP, focusing on team balancing. The PvE system aims to prevent multiple players from selecting the same class on one team and includes a unique prestige leveling system. Meanwhile, PvP offers more extensive customization in the lobby to enrich the multiplayer experience.
For PC players with mods installed for *Space Marine 2*, note that these mods will not work on the public test server. Additionally, while players can create and customize content on the test server using available assets, this content won't transfer to the main game, as the test server is a separate build. There's no official confirmation yet on whether progress or content from the test server will carry over to the main game, though it's not expected.
