Just create a ubernet game , join and click ready. As long as there are no other players the game will still start.
Single player would require AI, and well we don't have any real AI yet. The single player button is only there to remind ppl that there will be a single player mode. As soon as we have something that works we will turn it on.
This is exactly the feature I logged in to request. Yes, it will end the minute your commander lands, and there is no function to keep playing after the match ends. So basically you can create a solo game and move your commander 3 paces and then its game over. I gues it should not be to hard to make a free mode (Just 1 player, and remove all win conditions), That way you can get a feeling for all buildings, the ui etc etc. So the ai is for later put please give u pe possibility to explore solo (It's a feat I also would lile to see in the released game)
@warsocket: I really works that way! Create a new game. You have 4 spots. YOu take one of them. Then click ready. Ingame there will be three AI bases, that won't do anything. And you are free to do whatever you want for as long as you want.
