Thanks to us helping Valve with Cold Stream, they will release a beta version of Dead Air for Left 4 Dead 2. Dead Air will be available on the Xbox 360 later this summer with the full Cold Stream DLC.

Valve has added melee weapons, and made changes to the 4th and 5th map of Dead Air. Valve would like us to try it out and give feedback, especially about the finale.

Valve has tried something new with the Scavenge map in Dead Air, but they won't give away the experiment.

Cold Stream and the other Left 4 Dead maps will be out later this summer in the Cold Stream DLC.
