Cold Stream Releasing on July 24 for Left 4 Dead 2

[Shawn Zipay]

After over a year of vigorous testing, the Cold Stream campaign for Left 4 Dead 2 will finally be released in a "finished" format. But wait, there's more!

In addition to the Cold Stream campaign coming out for Left 4 Dead 2 PC players, the entire package deal (Cold Stream, Blood Harvest, Crash Course, Dead Air, and Death Toll) will also be released on the Xbox 360.

Additionally, Valve promises that there will be "some other surprises and details" but they are keeping quiet on that until the release date nears. They do promise to release all mutations in a selectable format when this content is released, meaning that players will get to pick and choose what mutation they want at any time.
