The Spitter

The Spitter is a Special Infected that made her debut in Left 4 Dead 2. The Spitter's mutations enable her to spit out a ball of mutated stomach acid which, upon hitting the ground, spreads out into a large pool. Any Survivors standing within the pool of acid take increasing amounts of damage based on how long the acid has been down; this can be up to 76 health with a single spit. Overall the Spitter's acid does the most total damage of any playable Infected, but is also the least reliable, as it only lasts for a short time, and once it pools out, it is stationary and relatively easy to escape. When killed, the Spitter leaves a small pool of acid around her corpse. She can sometimes be a bit difficult to hear, making faint squealing noises as opposed to the more distinct noises other Special Infected make, but the hacking noises she makes when she actually spits are relatively easy to hear.
