Full Cross-Platform Support Confirmed

Join via Friends List or Direct Invite
You can easily join and add friends on different platforms using the in-game friends list. Share your Friend Code to add them as a friend and join their session, or the host can send direct invites to friends on their list to bring them into the world. This works seamlessly across all supported platforms, including Steam, Epic, and Xbox.
Also Supports Cross-Save

Subnautica 2 also supports cross-save functionality, allowing you to continue your progress on another platform by importing your save data.
| Tip! | The host of a multiplayer session can upload the world save to the cloud. This allows other players to download the same file and continue the adventure in single-player even after the original host goes offline. |
