Microsoft dates Left 4 Dead’s Survival Pack on 360

Microsoft today confirmed that the ‘Survival Pack’ for Left 4 Dead, containing brand new content for the game, will be releasing on April 21st on the Xbox 360.

The new content is  two full campaigns of “Death Toll” and “Dead Air” for Versus Mode, and a new game mode called “Survival Mode”, which sees the four Survivors trying to survive the longest against multiple waves of the Infected.

Valve recently confirmed the L4D DLC would be free, which is super nice of them.
