Experimental Multiplayer Step by step instructions

Sorry about the process, it's a bit old school and we are currently implementing steam networking which should be a much smoother experience.
Basically: The host selects new server, and checks "host it locally". You'll need to set up port forwarding on your router and find your public ip address. The help button in the server setup talks about this. Give that ip to your guests.
The guests click new server, leave "host it locally" blank, enter the ip, and click join.
Thanks for that! I also just noticed that there is an option to join a game now, so I'll be happy to check that out soon :) Thanks again
i don't get the process... gave my IP address to my friends, but failed to join and vice versa.
