I was trying to host a game on Serious Sam: The Second Encounter because me and Cyberdemon are trying to do a co-op game. However, this is what is really ******* ******* me off the most. My game server is not listed what so ever. I left all the settings at the default. But it still does not appear. Any help will really ease my frustration
Try using Hamachi and updating SSt2E with the latest official patch. I still play with some of my friends online via Hamachi and it works wonders.
