Catch Swamp Fever in Left 4 Dead 2

Despite the (wholly premature, if you ask me) outrage of a vocal minority over Left 4 Dead 2, Valve will be shilling its zombie shooter at this week’s Comic Con convention in San Diego.

This means we’ll be seeing another stage from the brains-hungry sequel: the murky Swamp Fever. This bog-based campaign contrasts sharply with the blue skies seen in the previously revealed The Parish; you can see just how gloomy things get in the new screens below.

There’ll also be a peek at the “Spitter,” one of the new special Infected (also pictured below, and she’s a real looker). Apparently, she’ll be able to gob great clouds of acid over the Survivors, infuriating anybody who’s developed the habit of camping in corners (guilty as charged). She’ll be joined by “Mudmen,” essentially common Infected who scamper about on all fours in the swamp, aiming for a chomp on your delicious, fleshy knees.

Oh, and attendees will get to try out a bunch of new weapons, including an AK47, a grenade launcher, and the potentially hilarious cricket bat.
