The folks over at Gamespy recently got a hands on preview of the new Swamp Fever campaign in L4D2, exposing all the new details about the zombie infested bayou, along with the introduction of a new special infected… The Spitter.

Taken from Left4Dead Wiki

*The Spitter is a new Special Infected set to appear in Left 4 Dead 2.

It makes a hacking sound before spitting out what appears to be a ball of mutated phlegm, which upon hitting the ground spreads out similar to a Mortar round and changes from a sickish green gas like substance to blood red. Any survivors within the area receive small quantities of damage over time. This makes it exceedingly difficult to camp in one place too long, otherwise the Survivors health will slowly whittle away. It can be assumed the phlegm it shoots from it’s mouth has somewhat acidic properties, although it appears unable to pass through obstructions, even bouncing off hard surfaces such as walls. This brings to mind the question of whether or not the Infected could effectively spit at a wall from an angle an divert the phlegm to camping group around a corner.

The spitter was designed to split up tightly packed groups of survivors to make them easier to pick off by the other special infected.

Not much else is known about the Spitter, however, if the original Left 4 Dead campaigns are included in the sequel, it is questionable if they will be updated to include the Spitter, as it seems to be created specifically for the theme of the new campaigns. It’s even possible it will be exclusive to Swamp Fever, but this is unlikely.*

No official images of the Spitter have popped up yet, but if you squint hard enough, you can spot it in this video around the 49 second mark.

EDIT – We have an image. Quite disturbing!
