Valve has announced a new downloadable campaign for Left 4 Dead and Left 4 Dead 2. The DLC is entitled “The Sacrifice”, and includes three maps. It’s due to be released on 5th October for 560 Allards on the 360 (PC and Mac users will get it for free). The Sacrifice lets you play as the characters from the first game and reveals how the survivors from each game met during the past DLC campaign (The Passing).

Players will be able to decide which member of their team will permanently die at the end of the chapter. Valve will also be bringing the No Mercy campaign to the sequel. Previously, that one was exclusive to the original.
