saves/my-save.zip # This starts a server that will host the file created on the previous line saves/my-save.zip # This creates a new save, as if by clicking the New Game button in the GUI This can easily be done using the -create command-line argument. You will need to create your save file before you start the server, as the dedicated server REQUIRES a save file to be provided. Saves the game on exit (and autosaves normally)Ġ.13 onwards expects -start-server to be followed by a path to a save file.Game is paused while there are no players connected (though this can be overridden using the no-auto-pause option in the server-settings.json).Game starts immediately and loads a save given as a parameter to the command.

Graphics are not initialized (faster start up, less memory usage, works on completely headless servers).

You can run factorio -help to get a list of all command-line arguments that Factorio accepts. However, practical limit for this is much lower, popular streamers have managed to get well over a hundred players.Īs of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the -start-server command line option.

The hard limit for the number of players is 65,535.

Make sure there is no firewall or anti-virus blocking the UDP-packets.

Some routers do this and require additional configuration to prevent it.

Make sure your router does not randomize the source port on packets outbound from 34197.

Make sure you configure your router's port forwarding correctly for port 34197.

The game builds its own 'reliable delivery' layer built on UDP to deal with packet loss and reordering issues. The port can be changed in the config file.

All game instances need the installation of exactly the same game-versions and mods.

The host can also choose not to advertise the game at all, in which case you'll need the server's (public or otherwise reachable) IP address you can then Connect directly to that to join the game. Use the Multiplayer button in the Play menu to start playing a multiplayer game, choose New or Load or Scenarios to host and play, or Browse or Play on LAN to connect to an already-running game. Multiplayer games can be advertised to other players on the same LAN or worldwide. Multiplayer games can be joined, hosted while playing, or hosted by a dedicated server.
