Space Engineers is a voxel sandbox about building ships, stations, and bases across space and hostile planets. In co-op, the whole project is shared - you weld hulls together, wire reactors, and haul ore as a crew. The catch: the world save lives with the host. When they are offline, the build stops cold.

How SaveSync Keeps the Build Going

SaveSync syncs your Space Engineers save to every player in the group. After each session the latest world is distributed automatically, and any engineer can load it and host next. No one sits idle while one person is away.

Setting Up SaveSync for Space Engineers

Install SaveSync from Steam - every crew member needs it.

  1. Click Space Engineers in the list on the left. You’ll see Space Engineers’ save management page.
  2. Click “+ New Save” in the top right.
  3. Select your world from the dialog of available worlds. Check the in-game load menu if you are unsure of the world name.
  4. Click “Create Save”. The save starts syncing.
  5. Wait for the green checkmark.
  6. Click the share icon on your save.
  7. Search for your friend’s Steam username and click Share.
  8. Your friend clicks “Activate” on the shared save, which shows as shared by you. The world is ready, they can host it, and it syncs automatically after that.

SaveSync also keeps a full save history: who uploaded which save and when, with the option to revert to any earlier one.

One-time setup, then it just works.

Why SaveSync Beats the Alternatives

  • Big worlds, no manual hauling. Engineering builds balloon in size. SaveSync moves them so you never zip up a save folder for Discord again.
  • No stale-save accidents. Load an old copy and a session of welding vanishes. SaveSync guarantees everyone is on the current world.
  • No dedicated server bill. A group of friends does not need a paid server running 24/7 - any player hosting on the latest save covers it.
