Bring your crew. Pick your host.

The main game is announced for solo play or online co-op with up to four players. The group can explore and work on a shared Cloud Cruiser. This describes the main game, not a promise that every demo build supports multiplayer.

The developer describes Early Access as player-hosted client-server co-op. One player runs the host session; the others join it. The exact invitation menus and join steps must follow the released build.

A player-hosted session needs its host to be running. Schedule shared sessions with that player available. Do not assume automatic host migration, an always-on world or an offline continuation feature unless your build explicitly provides it.

Not in the developer reply checked here. The team said it was open to investigating player-run dedicated servers but could not promise them. Player hosting does not itself mean a headless dedicated-server download is available.

Before investing in a shared world, agree who will host and keep backups using the released game’s supported save tools. We have not verified a final save path, transfer procedure, client inventory persistence or demo-to-EA migration. Steam Cloud being listed does not establish those details.

The publisher lists both PC storefronts, but that alone does not confirm cross-store co-op. Check the launch announcement and your build’s invitation options before buying copies on different stores for a shared session.

Editorial first checks: ensure everyone uses a compatible game version, restart the host session and game clients, check the exact error message and review game firewall prompts. We do not prescribe guessed port ranges or a fixed upload-speed requirement. Capture the error and build number before reporting a recurring failure.
