How to get into the same game

Open the same project and check its server list or join instructions. Some projects offer public servers; others need a server address or a shared session. Friends should use matching game versions and any required game files.

If you can launch but cannot join, check the project’s server status and browser instructions. Keep the game tab active while playing. Voice chat and a game account, where needed, are handled by the project you open.
