Left 4 Dead Survival Pack DLC Now Available

The highly anticipated expansion pack for Valve's zombie thriller, Left 4 Dead, was released earlier today on Steam, as well as on Xbox Live. L4D fans will be happy to know that the Left 4 Dead Survival Pack is free to all owners of the game on both the PC and Xbox 360. The main feature of the Survival Pack is a new multiplayer mode called "Survival Mode", which includes 16 maps, leaderboards and seven new achievements. The premise is simple...survive a zombie onslaught of increasing intensity for as long as you can. In addition to Survival Mode, two new Versus Mode campaigns, "Dead Air" and "Death Toll", are now also available, along with an array of fixes, as is typical of Valve updates.
