Smoker

Summary
The Smoker is a very dangerous zombie found within ZAPT:R. It constantly emanates smokey particles, making it easy for survivors to identify it. Once a Smoker has caught sight of a player, the Smoker will attempt to grab the player with its long, prehensile tongue. Once caught, the survivor will have 3 seconds to free themselves before they are dragged. When dragged, the Survivor will be slowly pulled toward the Smoker, and they cannot do anything, nor free themselves, and must be saved by another teammate. The teammate can save the captured survivor by either killing the Smoker or tapping the player. When a Smoker is killed, its corpse will let out a cloud of smoke, which does not harm the survivors nor help the zombies.

Bot Smokers will generally silently follow the player, not willing to get any closer towards the player. If a Bot Smoker sees a player for the first time, he will attempt to grab them. If the target is out of reach or if the Smoker has already fired its tongue but had it broken, the Smoker will either stand by motionlessly or quietly follow the Survivors as they go about in the game.

Background Story
Many survivors recall having nightmares of their comrades being pulled away into the darkness by very long tongues, the tongue's owner not being visible. Once the captor has been found, it's usually too late; the Smoker has already killed its victim, and has now either ran off or has been shot to death. Survivors have developed a strategy to avoid these zombies by hiding in enclosed spaces where the Smoker cannot see them.

Some Blockheads believe that the Smoker was originally someone who was a heavy chain smoker before becoming infected. The credibility of these claims remains to be set in stone. Despite this, the Smoker still gets its name from this rumor.

Survivors

 * Smokers will never spawn when you are the only Survivor. Therefore, you won't need to worry about them in that case.
 * Use long-scoped weapons like the Hunting Rifle or Military Rifle to snipe these foes. A headshot will instantly kill the Smoker.
 * Check your surroundings, especially in high places. That's where Smokers love to creep around.
 * If a Smoker has grabbed a Survivor, it will become immobile, rendering it extremely vulnerable to damage.
 * Stay away from open areas, if possible, because Smokers can easily pull Survivors away while hiding in a hidden spot.
 * Do not ever go alone. Travel in groups to make sure that there is someone to save you from a Smoker's grasp.

Zombies

 * Try to hide in high areas. That way, Survivors cannot easily see you and shoot you.
 * If your strangle was just broken on a Survivor, they may take notice as to where you are. If that happens, instantly duck for cover, as they may try to shoot you down.
 * Lone Survivors are the best targets, since no one will be around to break your strangle.
 * If you start pulling a Survivor the moment they are in the air, they will be dragged to you much quicker than normal.
 * If a Survivor has been pulled all the way next to you, you will start clawing them, which will deal extra damage.
 * A Smoker's tongue deals 1 damage per half second.
 * If there are a group of Survivors creating chaos within a Technical Jeep (a modified jeep with a Heavy Machine Gun attached), try to pull the Machine Gunner out.

Trivia

 * The Smoker is one of the only five zombies in ZAPT:R to still retain their original L4D names, the others being the Jockey, Fallen Survivor, Tank, and Witch.
 * The Smoker is one of only three zombies to never spawn if there is only one player on the Survivor's side, the others being the Jockey and Tank.
 * The Smoker and the Jockey are the only two zombies in the game that can render a player helpless.
 * The Smoker is arguably considered the most dangerous zombie in the game, as even one of them could separate an entire team if they are not skilled enough.
 * Believe it or not, there is actually a limit of how long the Smoker's tongue can be, but it is not certain how long.
 * Player Smokers will not emit any of the smokey particles that the Bot Smokers emit. Thus, it can be pretty tricky to identify a Player Smoker, so your best guess is to see what the skin color is.
 * On maps such as Riverside Town and Eckfield Station, Smokers could instantly grab the first survivor they see immediately as the round starts.
