'Left 4 Dead 2' 'Cold Stream' update hits Xbox 360 this Friday

Delayed Left 4 Dead 2 downloadable content coming to Xbox 360 on Friday, August 3rd.

After getting caught in temporal murk known as Valve Time, the "Cold Stream" downloadable content for Left 4 Dead 2 will be released on Friday, August 3rd, Valve says.

"Cold Stream" will add five campaigns to the Xbox 360 version of Left 4 Dead 2 — the community-created "Cold Stream" and four campaigns from the original Left 4 Dead, "Dead Air," "Death Toll," "Blood Harvest," and "Crash Course." Additionally, all of Left 4 Dead 2's Mutations will be available to play at any time, instead of on a weekly, rotating cycle.

The "Cold Stream" add-on was officially released on PC and Mac last week.

The Xbox 360 version of "Cold Stream" will cost 560 Microsoft Points ($7.00) and requires about one gigabyte of storage.
