"Pre-orders are now running 95% over those of The Orange Box, and we're getting set to launch the pre-release demo and television campaign to further fuel this momentum," said Valve marketing VP Doug Lombardi in an official release.
Valve announced earlier today that customers who pre-order Left 4 Dead will receive access to the game's demo a full week prior to the November 18 release date.
Lombardi also announced the launch of a new Left 4 Dead contest, inviting fans to capture creative poses in front of Left 4 Dead outdoor advertisements. The entries will be judged by Valve's Gabe Newell, with the top 25 receiving free copies of Left 4 Dead. The grand prize winner will bag a new gaming PC assembled by AMD.
