Sorry, can't help you with this as I don't have the game. Why not ask here in the game forum? Pretty sure somebody has the answer you're looking for.

Yes, there is LAN. Internet MP doesn't seem to require Galaxy either.

Changelog for Patch 1.13.06 / GOG-12 (Windows)/ GOG-10 (Linux and Mac) (added 16 August 2016):

- We've just released an update for Satellite Reign. This build contains some significant changes to the networking backend. Basically, it allows players to connect to one another directly, rather than via the Unity relay servers (though the relay servers are still there as a fallback). This not only allows for significantly lower latency, but it should also get around some player's inability to play together from different regions.

- Having said that, while this should allow friends in different regions to connect, they still won't show up in the default server list. However, if you change your filter to "Friends" you should see any games being hosted by people on your friends list, regardless of their region.

- When you're connected, you'll see one of the following in the menu, next to the version number:
- [DC] - Direct connection. Exactly as it sounds, you're communicating with the host directly over the internet.
- [PT] - NAT Punch-through. A service hosted on our own server facilitates the connection between the client and host, after which point they will communicate directly.
- [RL] - The Unity Relay servers. This is the existing communication method, where all traffic is routed through Unity's relay servers.

Changelog for installer update / (Mac) (added 16 December 2017):

- Installer update - No game files were changed.
