Left 4 Dead Sells 1.8 Million at Retail

Valve's cooperative zombie-shooter Left 4 Dead sold over 1.8 million copies at retailers in 2008, distributor Electronic Arts revealed in a conference call today. nope

The figure accounts for retail sales of the PC and Xbox 360 versions, but does not include those copies sold via Valve's digital distribution platform Steam.

Nor does the figure include total worldwide retail sales, as Valve reminded us that EA Partners handles its retail distribution in "most, but not all of the world."
