Valve's Doug Lombardi has revealed that their upcoming zombie kill-athon has already exceeded the Orange Box for pre-orders, speaking with VGChartz.
He said this was mostly down to the 10% off promotion which had "driven largely" the retail pre-order sales. The demo and a massive ad campaign will help that trend he adds.
"Sales goals are hard to truly define until you get close to launch, especially with a new game property," said Lombardi, VP of marketing. "However, we're getting close now and it looks like Left 4 Dead may do ok." I have a feeling it might do just a little more than 'okay'.
"Pre-orders for Left 4 Dead are currently exceeding Orange Box pre-orders by well over 40%, this driven largely by the 10 per cent off promotion being offered now for both versions," he continued.
"And one could assume this trend over Orange will continue as the pre-launch demo hits and the largest consumer advertising campaign for any Valve game begins on buses, buildings, billboards, TV, magazines, and web sites in the next couple weeks."
Left 4 Dead is being released on Xbox 360 and PC this November 20th.
