Valve has announced that the new DLC for Left 4 Dead 2 called "Cold Stream," after a series of recent delays, will arrive on Xbox 360 this Friday, along with an update of the game. The expansion will cost 560 Microsoft Points and will insert the new campaigns Crash Course, Death Toll, Dead Air, Blood Harvest and Cold Stream , the first campaign totally created by the community to become official.
