It's important to note that while *Warhammer 40K: Space Marine 2* is available on PlayStation 5 and Xbox Series X|S, the public test server is exclusively for PC players. If you're on PC, accessing the public test server is straightforward through Steam.

To join the test server, simply search for *Warhammer 40,000: Space Marine 2* in your Steam library. The public test server should appear right below the main game as a separate title. Remember, you must own a copy of *Space Marine 2* on Steam to access the test server. Once you find it, download and install the test server, which operates as a standalone build separate from the main game.

The *Warhammer 40K: Space Marine 2* public test server offers new content for both PvE and PvP modes, including new weapons and customization options. The bulk of the updates are focused on PvE, featuring a new map, relaxed class restrictions on weapons, and tweaks to online gameplay features. Keep in mind, the content, especially the PvE additions, is still under development and may change before the official release.

In terms of online gameplay, the test server improves matchmaking for both PvE and PvP, enhancing team balancing. The PvE matchmaking system aims to prevent multiple players of the same class from being on the same team and includes a prestige leveling system. Meanwhile, the PvP mode offers expanded lobby customization to enrich the multiplayer experience.

For those with mods installed for *Space Marine 2*, note that these will not work in the public test server. Additionally, while you can create and customize content using the available assets, this content won't transfer to the main game as the test server is a distinct build. There's no official confirmation on whether progression or content from the test server will carry over to the main game, but it's generally not expected.
