Valve showed off Left 4 Dead 2's Parish at E3, but Comic-Con is all about Swamp Fever.

The gallery gives us a look at some of the dark, muddy settings for the area as well as one of Left 4 Dead 2's new infected monsters, The Spitter. The female Spitter has an area attack and cute little pigtails.

Valve says they have at least one more boss infected to reveal before the game hits PC and Xbox 360 on Nov. 17.
