Valve has revealed another new campaign set to appear in Left 4 Dead 2
at San Diego Comic-Con. It's called "Swamp Fever," and, as the lovely lobby poster
you can view in the gallery below states, "The Only Cure Is Dying." Harsh
! It's packed with Mudmen, Spitters and all sorts of nastiness you'd expect from a zombie-filled swamp. We've spent some quality time trudging through the level on the convention floor and will have a full writeup on the bone-rattling experience soon.
