Valve is known for taking their time to polish off their releases, and the latest DLC update for Left 4 Dead 2 is no exception. The Cold Stream campaign has been in development for over a year, but Valve has announced a release date and Xbox 360 players will finally get their hands on new Left 4 Dead content later this month:
"After months *cough*year*cough* of play testing not just the Cold Stream campaign on the PC but the entire DLC consisting of Blood Harvest, Crash Course, Cold Stream, Dead Air, and Death Toll, we are ready to release on the Xbox 360.
The date will be July 24th. There are some other surprises and details we will give you later but for now we just want to confirm an often requested feature. With the update going out at the same time (also for the PC), all of the mutations will be available at all times. This will allow players to choose to match into games playing Taannkk!, Gib Fest, or even a user created mutation like Confogl.
Stay tuned for more information in the coming weeks as we get ready to launch."
The PC version will be released for free, but Microsoft may require Valve to charge for DLC content over Xbox LIVE. We'll have more details on the update and pricing later this month.
