I think its going to be a long time before I get an invite. The first wave went to alot of the Blizzcon attendees hell not all the Blizzcon attendees didn't even get an invite yet and there is over 20K in the Beta right now. Something about server strain. Wave 2 is looking to get more Blizzcon attendees so going to be SOL. People have cracked it but I don't think you can play the comp its strictly a MP beta. SC2 looks so very good although watching videos Roaches are OP.
Yeah had to download some stuff playing against the AI. The AI isn't great after you know its tendency's. I can send you the information on what you need if you want.
