Valve's free downloadable content pack for the hit zombie shooter Left 4 Dead goes live today, with the desktop version hours behind.
The Survival Pack adds the frantic pace of Survival mode and brings the Dead Air and Death Toll campaigns into Versus. Xbox 360 gamers can enjoy the new canned goodness right now.
Those with twitching fingers on a mouse however will have to wait as the pack is "targeted for release later in the day." Still the DLC is free so what's there to complain about really?
