Noticed some new stuff watching the video in the new format. After Gordon and his buddies maneuver through the ruined building to the flank of the roadblock you can see a Combine Soldier in a tower overlooking the roadblock. As Gordan gets closer the Soldier says something and sets off a flare. The combine troops manning the roadblock then turn around to face Gordon and within 15 seconds one of the helicoptor-hovercraft-bug-thingies shows up and starts attacking. If Gordan had shot the guy in the tower before the flare was fired, would the bugcraft thingie not have shown up? Anyway Half-Life 2 looks awesome and I can't wait to play it.
P.S. I've been out of town for the past few days, do we know if HL2 has been delayed or not? or is it still up in the air?
