The end is nigh. The infected are lurking everywhere and chances of survival are slim. Left 4 Dead focuses on the story of 4 individuals and their harrowing battles against the hordes of the infected that roam the streets. What about other survivors? What would they look like and what kind of deformed monstrosities would they be up against?
Primary attack: The puss bubbles burst, flinging some horrid slime around and then maybe flies come swarming out of the puss sacks, blinding the player for a time with the over whelming sound of buzzing and just thousands of flies in front of the screen.
Secondary attack: His hands can claw and do some nasty damage if you get close, and again at a close range his sacks will start to pop and release nasty stuff.
