Space Engineers Co-op When the Host Is Offline
Host is offline and your Space Engineers world is stuck with them? SaveSync lets any player load the latest save and keep building.
You and the crew were mid-build in Space Engineers - and now the host is offline for a week. The reactor is half-wired, the cargo ship is half-welded, and none of you can touch it. The world is locked to one person’s machine.
Why the Host Owns the World
Space Engineers co-op runs through the host’s session. The world save is theirs. Everyone else joins in, but the file never leaves the host - so when they stop playing, the build is unreachable.
SaveSync Hands the World to Everyone
SaveSync syncs the save to the whole group automatically. When one person finishes a session, the next player just opens the latest world and hosts it themselves.
- Install SaveSync - everyone in the group needs it.
- Create a sync group and add the save folder once.
- Whoever played last syncs automatically on close.
- Whoever plays next loads the latest world and hosts.
No more waiting on one person. No more frozen builds.
For the full setup walkthrough, see the Space Engineers save sharing guide.
Stop Waiting on the Host
If your crew plays regularly, host availability is the only real bottleneck - not the game. Get SaveSync on Steam, set it up once, and the host being offline stops mattering. One purchase covers every supported co-op game too.
