Comic-Con's Swamp Fever: new screenshots, video of the Left 4 Dead 2 bayou

What's more wicked than the fact that new Left 4 Dead 2 star Rochelle showed up wearing a pink Depeche Mode T-shirt? Not much, but the rest of the screenshots and video (courtesy 1up) below and behind the jump come quite close.

Valve is showing off the Swamp Fever episode on the floor of Comic-Con, including a newly unveiled boss monster, The Spitter (seen over there to the right, and I mean, ok, yeah, I guess -- I think the fact that she's still stuck in dirty pink heels somehow gives me the willies more than her gaping bloody maw), who, they say, "has an area attack that can split up Survivors or flush them out of their hiding spots."

Other things to be gleaned from the new footage? Infected hiding below the surface of the swamp-water are going to be a newly terrifying challenge, and the fact that that flamethrower -- if the 1up crew's performance is any guideline -- is going to have to be wielded very, very sparingly and carefully.

Two more videos and five hi-res screenshots await after the jump.
