Today Valve rolled out the second television spot for Left 4 Dead 2. It's set to air in North America this week and in Europe next week.

The advertisement seems to be a shorter, remixed version of the intro movie that was recently leaked to the Internet. It was a pretty awesome movie so it seems like a good idea to use that in marketing the game. The song used in the commercial is "Electric Worry" by Clutch.

L4D2 hits the PC and Xbox 360 on November 17th. The demo's currently available for everyone except Xbox Live Silver members.
