The Jockey

The Jockey is a new form of Special Infected that will appear in Left 4 Dead 2. It will attack Survivors from behind and will cling on to them. From there, they can control the Survivor while doing so. It appears that the Jockey has been mutated by the infection to the extent that he has a hump, which is what causes him to hop around in a spider monkey like motion. However, he can jump great distances, yet nowhere near as far as the Hunter. When on a Survivor he claws at them with his free hand while leaning in a direction to cause the Survivors to stumble. His only description for now says that he wears an extremely colorful shirt, mostly red and purple, and his sound is laughter. It was first mentioned here.
