Space Engineers

Space Engineers uses a UDP gameplay port and a Wine-backed community server container. The Swarm Hosts wrapper initializes a default Star System world and dedicated-server config when the data directory is empty.

Quick Facts

Launch Notes

  1. Choose Space Engineers.
  2. Let the first launch initialize the default world, or upload an existing world and SpaceEngineers-Dedicated.cfg through the file manager.
  3. First launch downloads the Windows dedicated server payload through SteamCMD, so startup can take several minutes.

Data

World, config, and dedicated server binary data live under /appdata/space-engineers.
