The zombie apocalypse is back, and I finally had the chance to play Valve's demo for the much anticipated and much maligned Left 4 Dead 2. I had to wait longer as I was not among those who got to play it earlier because of a preorder. Aside form the uselessness of get an early demo of a game you've essentially already bought, it seems like this is Valve's chance to surprise it's die-hard fans. I can at least say that I'm glad I don't ever preorder games.
