The Smoker

The Smoker is an Infected with a long, whip-like tongue that can drag Survivors away from their team-mates and use its tongue as an organic noose to strangle Survivors when it is perched above them. Similar to Half-Life's Barnacle, or Resident Evil's Licker. When killed, it leaves a haze of black smoke, distorting the Survivors' vision and disabling character speech. Like most other boss infected, a melee hit from the Smoker does about twice as much damage as the Horde.

Tactics
Survivors

Identified by its hacking and coughing, the Smoker is one of the most deadly if the Survivors are being attacked by the Tank or the Horde. The problem is that the Smoker is generally further away than a Hunter would be. You'll need assistance from a teammate to un-noose you unless you can quickly shoot it before you lose control. It can sometimes be hard to find the Smoker but the easiest tactic is to shoot it after it has lassoed a teammate because the tongue leads right to it. Your character cannot talk in smoke, only cough, choke, and hack.(You can still type and use voice chat)

Tip: If a fellow survivor is roped and you can't see the smoker to fire at it, punch the survivor, it does no damage to them and they also get released.

Infected

If you're playing as a Smoker, a common yet useful tactic is to always have the advantage of higher ground. Choking a Survivor from above is far more effective than dragging a Survivor straight to you. Being higher makes it harder to see and kill you, giving you the advantage.

The key point to the Smoker is to be patiant wait untill the survivors are distracted by the horde or other distractions.

▲The Smoker also works well with the Hunter. A good, common scenario to show this is lets say the four survivors have split up into teams of two. A Hunter and a Smoker can easily team up to kill the two survivors by having a Smoker grab the first survivor and a Hunter to pounce on the second one immediately afterward.

▲The Smoker is the Tank's best friend. Make sure if you're a Smoker during a Tank battle to stay a good distance away and pull a survivor away from the Tank. This takes pressure off of the player, and during the confusion you may even be able to kill the survivor while the Tank takes care of the rest of the survivors.

▲If one survivor has been vomited on the boomer launch you tounge to pin him down while the horde take thier pickings. If things go well you will slowly drag the survivor towards you and begin ripping the flesh of his/her body.
