What are the names of the zombies in left four dead?

Answer 1

• The Boomer is a bloated infected that can spit vision-impairing bile on the Survivors that attract hordes of infected, and explodes on death, spewing more bile in the immediate area

• 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.

• The Smoker is a horribly deformed zombie, with its right arm completely covered in boils and blisters, and the right side of its face is swollen and blistered. It has a long tongue that he can use to ensnare a Survivor and then drag him back to himself, either attacking the Survivor directly, allowing the horde to attack the Survivor, or leaving the Survivor suspended over a cliff or roof edge; the Smoker only releases its victim if the tongue is shot or on death, at which point it dies in a burst of vision-clouding smoke for a brief period.

• 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 knock cars and other debris into the Survivors. In 2010 IGNranked Tank 51th in "Top 100 Videogames Villans".

• The Witch is a passive female infected that stays in a spot, crying; Survivors can sneak by the Witch, but if they disturb her with light or loud noises, she will become aggressive and attack the Survivor that alerted her, usually incapacitating the Survivor and attacking him until she or the Survivor is killed, except when playing on Expert difficulty, where she kills the Survivor instantly.
