Grounded 2 crossplay platform support
Grounded 2 has confirmed cross-platform play between Xbox and PC. The official support matrix covers Xbox Series X|S, Xbox Cloud Gaming, Windows through the Xbox app, and Steam on Windows.
| Platform | Online co-op | Confirmed crossplay path | Account requirement |
|---|---|---|---|
| Xbox Series X | S | Yes | Xbox and PC |
| Xbox app on Windows | Yes | Xbox and PC | Xbox account |
| Steam on Windows | Yes | Steam, Xbox app, and Xbox console | Linked Microsoft account |
| Xbox Cloud Gaming | Yes | Part of the Xbox and PC ecosystem | Xbox account and eligible cloud access |
| PlayStation 5 | Up to four players | The store listing does not claim cross-platform play | PlayStation Plus for online play |
For a mixed Xbox and PC group, every Steam player should complete the Microsoft account link before the session begins. This prevents the account step from interrupting invitations or world access.
Set up crossplay on Steam
- Update Grounded 2 to the latest available build in Steam.
- Install the Xbox app and Gaming Services on Windows.
- Launch Grounded 2 and use its crossplay access flow.
- Sign in with the Microsoft account that owns the Xbox profile you want to use.
- Restart the game after installing or repairing Xbox services.
- Enter online co-op and join or host the shared session through the linked profile.
The Microsoft account is required for Steam cross-platform capabilities. A Steam login by itself does not provide the Xbox identity used by the confirmed crossplay path.
Crossplay, cross-progression, and co-op
Crossplay lets players on supported platforms enter the same online session. Cross-progression carries save progress between PC and Xbox console. Online co-op describes the multiplayer mode itself, regardless of whether every player uses the same platform.
Xbox Play Anywhere adds a separate ownership benefit. A digital purchase in that program works on Xbox console and the Xbox app on PC, and the save follows the signed-in Xbox account. A Steam purchase remains in the Steam library even after a Microsoft account is linked for multiplayer features.
Grounded 2 supports online multiplayer and co-op. Local split-screen and offline co-op are not supported, so every member of the group needs their own supported device and online access.
Fix Steam sign-in and Gaming Services
If the crossplay option is disabled or the game crashes during the Steam login, use this order:
- Close Grounded 2.
- Install or open the Xbox app on Windows.
- Install Xbox Services if the required services are missing.
- Run the Microsoft Gaming Services repair process.
- Restart Windows, then reopen Steam and Grounded 2.
- Use the crossplay flow and link the Microsoft account again.
Obsidian's launch hotfix tied disabled Steam crossplay to missing Gaming Services. Its support article gives the same dependency for login crashes, making the service repair the first targeted fix before reinstalling the full game.
