Valve’s Chet Faliszek announced on Gametrailers TV about the upcoming DLC “The Sacrifice” which will be detail how Bill died and will be available for both Left 4 Dead 1 and 2. Most importantly, it will be free for the PC and MAC users.
“The Sacrifice” for L4D2 will allow players to play as the first game’s characters and even be able to choose which member of that crew will end up having his or her brains eaten by the horde and L4D1 users will have it too. Along with the DLC, a 150-page comic strip will also be available in four parts that details the back story until the new DLC.
No particular release date or pricing (for Xbox360 users) were mentioned but it should keep fans excited for a while as this is not the final DLC.
