December 14, 2009 
Valve broke news this morning that Left 4 Dead 2 would be getting a new Downloadable campaign next year called “The Passing”. This campaign will bring back the cast from Left 4 Dead 1 making a total of 8 survivors!. VP of Valve said “This is the most important campaign of Left 4 Dead.”
Wow, that sounds pretty cool, and if they allow 8 survivors on screeen at one time… how crazy is that going to be playing?! Can’t wait!.
