The SteamWorks Online SubSystem has been implemented for multiplayer in Axion.
Any online servers will be visible in the Steam server browser. Access the browser by clicking on View-Servers-Change Filters and change "game" to Axion.
To host an online game, forward ports 7777 and 27015, then choose one of the "NET" options for starting a server in the Axion launcher.
To play a LAN game, just choose one of the "LAN" options under "start server" in the Axion launcher. This server will also be visible in the Steam server browser but only to players on your local network.
To join a server, right click on it in the server browser and choose "view server info". Then copy the IP address and choose "join game". The Axion launcher will start. Click on "Join Server" in the Axion launcher and paste the IP address.
Player location is now displayed at the top right corner of the HUD in the form of an X-Y coordinate. This will be tied in with the map when the new level design is complete. For now, it can still help with navigation if you use it to meet up with people in multiplayer or track the coordinates of locations to return to later.
