Holy. Crap. 

I hope you're sitting down, because the three minutes of Left 4 Dead 2 footage above is more incredible than I had thought it would be before I pressed play. And believe me, I had pretty high expectations. I'll also be honest, I don't know what it is -- the game's intro, a really expensive promo video, or a message from God. But when it's this awesome, who cares?

Left 4 Dead 2 ships in November, and I'm thinking about starting up a petition to get Valve to ship it next week. Who's with me?
