The single-player aspect of StarCraft II was honestly one of the more intriguing elements shown off at this year's Blizzcon. Thanks to Gamevideos you can watch the entire live demonstration by Blizzard's VP of Game Design Rob Pardo for yourself. Since the Zerg have yet to be unveiled, this video is unfortunately sans Kerrigan. Instead you will see how the mission briefings, open-ended storyline and game progression will work for the Terrans.
Hit the jump for the second half of the demonstration.
