Gunker

Overview:
The Gunker is a slow, toxic zombie with the ability to spew acidic bile from a distance. The Gunker also has a very keen sense of smell, enabling him to detect humans behind walls. They can be told apart from a normal zombie by the toxic green smoke that wafts off of them.

Abilities:

 * The Gunker can spew a close-range acid vomit which will coat a wide area directly in front of the Zombie.
 * The Gunker also has an alternate attack which launches a single long-range projectile, which upon contact with a surface, will create a lingering cloud of noxious gas that poisons and damages humans that walk through it.
 * The Gunker will see every human on the map with a green outline, even through walls!

Playing as:

 * As a Gunker, you can avoid being on the front-line due to your ranged nature. Hang back behind other zombies to prolong your life, and to allow them to finish off humans that you have weakened with your vomit.
 * Your close-range attack is best used when humans are up-close and in your face, then use your sword to deal massive damage to them.
 * Your long-range attack is good at assaulting distant humans, but also covering an escape. If you are about to corner a human, create a cloud behind you so that he can't escape unharmed.
 * You can use your ability to smell humans to guard the Fatkid from hidden players, and cloaked players alike. Vomiting on a cloaked human will reveal them for a short moment.

Playing against:

 * The Gunker is incredibly deadly as a supportive zombie, they should become a target priority.
 * If a Gunker is present, avoid trying to cloak or hide behind a wall. Using the cloak will only waste it, and hiding behind a wall is fruitless. Take down the Gunker first.
 * If a Gunker vomits on you, try to retreat to your fellow humans. You will have blurred vision, and take critical damage while coated.

Trivia:

 * The Gunker was the first Special Zombie added to the game.
 * Although many fans compare the Gunker to the Boomer from the Left 4 Dead series, the Gunker is actually functionally much more similar to the Spitter from the Left 4 Dead series.
