Valve has announced a special promotion granting those who pre-order Left 4 Dead early access to the demo and a 10% discount. The demo will be released on November 6th to Xbox 360 and PC gamers that pre-order and everyone else will be able to play on November 11th. The demo will also no longer be available after November 18th.

"Every time someone plays Left 4 Dead, we witness the most overwhelmingly positive reaction that we've seen from any of our games," said Gabe Newell, president and co-founder of Valve. "This gives us tremendous confidence in the product and why we've taken the game on the road, produced this pre-launch demo, and invested more advertising dollars on the title than any prior release from Valve."
