// how players connect

Connection string: fc.gsb.gg:<assigned-port>

Once your server is running, the bot posts the live connection URL in your Discord channel each time the server starts.

// auto-shutdown

When the last player disconnects, the bot waits 15 minutes for someone else to join. If nobody does, the server saves your world and shuts down (stopping it yourself with /host stop saves it the same way). Next start cold-starts in about 30seconds and picks up from that save.

Is Space Age DLC supported?

Yes. Toggle Space Age in the server config and the save loads with the expansion enabled. Each player still needs their own Space Age license to join.

Can I upload an existing save?

Yes — use `/host world-transfer` in Discord. `direction:export` gives you a private link to download your world as a `world.tar.gz` backup; `direction:import` gives you an upload link and we restore that archive on the next start. To bring an existing save in, wrap your Factorio `saves/` folder as a `world.tar.gz` — run export once first to see the exact layout to match.

Does this handle late-game megabases?

Headless servers shift CPU work to the host, but megabase simulation is still demanding. Auto-shutdown still applies when nobody is on, so treat the server as a checkpoint between sessions, not a 24/7 megabase host.

Can I switch to a different game later?

Yes. We back up your Factorio save before the switch and restore it when you come back.
