<Li> The Hunter is an agile foe that can jump and pounce on a survivor, and then tear at his victim until he is knocked off, kills his prey or is killed . A hunter emits animal like screeches or light roars when close by, and a snarling growl can be heard when in close proximity . The Hunter is signaled by a startling high pitched piano cue . </Li> <Li> The Smoker is a boil - covered creature with six long tongues that it uses to ensnare and drag a survivor back to himself . It may then either attack the survivor directly, allow the horde to attack him, or leave the survivor suspended over a cliff or roof - edge . The Smoker only releases its victim if a teammate shoves the ensnared survivor, if the tongue is shot, the survivor is killed, or upon the Smoker's death, which results in an explosion that leaves a vision - obscuring cloud . Smokers have raspy voices and frequently wheeze and cough, presuming that they may have been an avid smoker before becoming an Infected . A 2 - note low piano cue signals the Smoker . </Li> <Li> The Tank is a gigantic, muscular infected that has the ability to swipe at survivors, knocking them off their feet and incapacitating them; it can also throw rocks and knock cars and other debris into the survivors . The Tank looks like its lower jaw is missing, but it's actually hidden in its neck muscle . The Tank is the most durable of all the special infected, and requires the full support of all of the survivors in order to be killed . The Tank is accompanied by a booming orchestral score to signal his appearance . </Li> <Li> The Witch is a female infected with long claws that stays crying in one spot . Survivors can often avoid the Witch but if they disturb her with light, loud noises or gunfire, she will become aggressive and charge at the one who "startled" her . Along with crying, an eerie choir tune plays when she is near . The Witch has the strongest attack of the infected in the game; able to kill a survivor outright with one blow on the hardest difficulty . As such she is not playable by human players in Versus mode . </Li>
