When you launch a game on the multiplayer platform, you can activate an option that will let any player passing by the multiplayer lobby to join in at any moment and take control of one of the AI faction. If he disconnects AI resume control of that faction.
This means you can launch all your single player game via the MP lobby and eventually have a worthy opponent showing up to spice things up .
I have been playing a game with this option on in the last days but haven't seen anybody joining, just had one player connecting and disconnecting without a word. I guess the player base is not very large at the moment, explaining the lack of players, but I also feel the devs have not advertized the last beta patch note and nothing was said on this function.
So don't hesitate launching your SP game on the MP lobby and have a look at the lobby anyway before entering your single player game, playing against human player just makes this game so much better!
