Left 4 Dead 2 “The Passing” DLC Screens

February 12, 2010 – Yesterday at X10, Valve revealed more information about “The Passing,” the upcoming DLC package for Left 4 Dead 2 that will add an entirely new chapter to the game and will feature the survivors from Left 4 Dead crossing paths with Left 4 Dead 2‘s survivors.

“The Passing” won’t feature Bill, Louis, Zoey and Francis as playable characters, but it will flesh out their story and, shortly after “The Passing” is released for Left 4 Dead 2, a DLC chapter will be released for Left 4 Dead that shows how they came to be in the southern United States.

“The Passing” will add a new uncommon common infected and looks pretty impressive in the new screens, which can be seen below.
