TVGB: "Valve has sent over the second TV spot for Left 4 Dead 2 that will be airing throughout North America this week. While the first one swung a baseball bat at us, this one consists of footage from the lengthier video we saw a few weeks back, all cut up into trailer form for quick digestion. And in case you're wondering, the song is "Electric Worry" by Clutch. Oh, and the public demo's out, too."
