Hi
@BeYkeRYkt - yep. You can start a headless server by launching the game with -headless, like so:
Terasology.exe -headless
In-game you can shut it down again from a connected client in the console using "shutdownServer"
However, the autosave functionality hasn't been merged yet, so any crash will make the world disappear. This feature is likely to be merged and available in the next stable build. Probably should be within a couple weeks or so
