Saturday March 19th is going to be an all-day multiplayer Clones-a-thon. To join in on the fun simply start a server and wait for players to join, or join an existing server and then play until your hands are numb (optional).
If you plan to host matches then port forward 9877 UDP. This is not necessary but it will improve the chances that other players can connect without any problems. For more details read this: http://clonesgame.com/port-forward
We are going to be testing out some new levels to be released in the next Multiplayer Jam Pack. If you've created your own levels then load them up, levels are auto-downloaded when a player joins your server.
