Left 4 Dead 2 Cold Stream DLC hits Mac, PC; 360 delayed

Valve has finally let loose the much-anticipated Cold Stream DLC pack for Left 4 Dead 2, but the Xbox 360 version is AWOL.

"We are working with Microsoft on a release schedule. We don't have an ETA yet but we hope to have it out soon," the dev team said on Twitter.

Cold Stream is based on a community campaign which Valve liked well enough to make official; it includes the maps Cold Stream, Blood Harvest, Crash Course, Dead Air, Death Toll and No Mercy, as well as some "surprises", mwa ha. It's free on Mac and PC but will be 560 MS Points for Xbox 360.

If this DLC has blindsided you, you have only yourself to blame; it was announced as far back as February last year and has been wallowing in Valve time ever since. We've only had the release date for just over three weeks, naturally.

Thanks, Joystiq.
