The Buzz: Left 4 Dead Opening Cinematic

Here is the opening cinematic for the upcoming game Left 4 Dead and all I can say is "WOW!" The quality and cinematic quality of this is amazing. I was also watching some of the gameplay footage and it is INTENSE. The only thing I worry about is team killing and friendly fire; with that many zombies piling all over you it will be very easy to kill your friends. Anyway take a look at the video and let me know what you think.
