Ticker

Summary
Tickers are trapped within a hazmat suit. At first, many believed they were some poor souls who were sent to contain this virus, but due to their sheer numbers, this is impossible. And since they have tanks that contain extreme levels of radiation and perfectly fine suits with no damage or signs of attacks, it is safe to assume that these zombies were not created on the day the outbreak began, and someone, or something, is out there, stuffing zombies in suits, giving them radioactive waste in tanks, and sending them to kill survivors. No matter where it came from or why it is like it is, this Infected is deadly to an unprepared or holed-up survivor.

Controls
Basic Claw: Basic attack which deals 10 HP of damage. Consumes no energy.

Tips

 * If a Ticker is moving backward with the intention for you to make them explode, it is recommended to either get a safe distance from them and blow them up (by shooting their tanks), or knock him down and cleanly shoot his head until he dies.
 * They can easily hide in crowds of zombies and are more common than you think. If you see a Ticker far away, attempt to shoot it before it gets close, as someone can shoot the tanks. If close, melee it and flee before getting blown up.
 * Try to stay behind or under walls and ceilings. They can provide protection for you and damage the survivors with radiation if they blow you up you will leave radiation that'll drain their Health twice as fast.

Trivia

 * Presumably, this is the Boomer from the Left 4 Dead series Reason 2 Die: Awakening counterpart.
 * The Ticker uses a Pinewood Emergency Team Hazmat Uniform, hence the emblem on the front of the suit.
 * The Ticker can be used to snuff out camping survivors (such as the secret underwater cave in Panama Beach), as its radioactive field will inflict constant damage through any surface.
 * Tickers are slightly slower than the average zombie.
 * You will not get the $50 for killing a survivor if your radioactive field kills them before you can damage them yourself. This also applies if you kill survivors either by exploding on them or if they get too close to radioactive puddles on the ground.
 * Oddly enough, the puddles of radioactive waste may relate to the Spitter from Left 4 Dead 2, as she drops a damaging patch of acid when killed.
 * After the Ticker's initial death, it's tank can still be blown up only if it didn't explode yet.
 * Before Update 0.7.9, the explosion caused by shooting the Ticker's pack affects everyone in the blast range, but today, it will only affect the one who shot it and will also kill zombies near it, which (in theory) could be useful for clearing out hordes near the Ticker.
 * Ticker's puddles can now be cleared with a fire extinguisher (As of update 0.8.5), making camping a lot easier.
 * Ticker puddles can be also seen in maps but it might be a glitch such as the puddle on cake kingdom.
 * The name of the creature is based on the sound the radiation makes when you get close to it.
 * You get 18.18% EXP when killing this zombie.
