Left 4 Dead 2 Dead Air DLC Beta On Steam Now

Valve's reward to fans for playing through the Cold Stream L4D2 DLC is here. The Left 4 Dead 2 update of L4D campaign Dead Air is available for play on Steam. Well, the beta is anyway.

The developer has done more than add melee weapons to the campaign, hinting it "made some changes to the 4th and 5th maps of the campaign." Valve also teases changes to the Scavenge map.

The Dead Air DLC will be hitting Xbox 360 later this summer.
