All i can say atm is THOR! Build this unit and listen to Arnold speak!

They're big and powerful and the murauders are cool units too, yes im playing the Terans. The beta is multiplayer only with an option to play against the AI only in very easy mode. Ive been doing this last few hours just to get use to the races before i go up against players.
I can't help thinking all SC2 is an grfx update of SC1 with extra units added, even the same sounds are there. The Campaigns better blow us away or the only ppl that will still be playing SC2 after the rest of us are done with the campaigns, is the Koreans.
Still its worth buying when it comes out.
