It's been a long time coming, but the Cold Stream DLC will arrive on Xbox 360 this Friday, August 3, according to Valve. The Cold Stream update, which is already available on PC and Mac over Steam for free, will cost 560 Microsoft Points ($7) on the console.

Cold Stream includes the fan-made campaign of the same name, along with the four original Left 4 Dead maps: Crash Course, Death Toll, Dead Air and Blood Harvest. Friday night we'll see if the new pack gets people "RELOADING!" the three year old game.
