"Don't worry, the radiation coming from these guys won't give you cancer. Maybe."

Walther's Notes - Restored

This note was found lost in the streets, wet and muddied. It has since been partially rewritten through conjecture.

One of the things to comprehend are the workers of many jobs out there, formerly ready for duty. Those did not take long to show around the city, people in hazmat suits moaning and roaming for flesh. They cannot eat because of the mask, but they can still harm and is more than willing to do so. Perhaps to speed up the manslaughter? The actual threat, however, are those little cylinders of theirs. Spilling toxicity and radioactivity all over the place, a true living bomb. It is very crucial to never shoot them from behind as you won't be killing to dispatch of the problem, but creating another. Fortunately for you, cancer itself won't be the cause of ceasing your adventures.


Tickers are slow and durable zombies that emit radiation from themselves. They do more damage than a Normal Zombie and can deal low to high amounts of damage with their radiation. When a Ticker's tanks (found on their back) are damaged enough, the tanks will explode, dealing damage to (and possibly killing) all nearby zombies and the survivor who has shot the tank. The explosion will leave a large pool of liquid radiation, which will deal constant damage to nearby survivors. Radiation damage will become more severe the closer a survivor gets to the Ticker or pool of radiation. Since the radiation damages through walls, Tickers are ideal for damaging or forcing out stationary and camping survivors.

Background Story

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.

Since they also 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.

Analysis of Ticker corpses was inconclusive, with some believing they can vaguely remember the company whose logo is present on the suit. Tracing down the source is currently impossible.

Rush: Run in a straight line in the direction you are currently facing. Upon contact with players or a solid object, you will blow up. This action will continue until you make contact or run out of energy. You have to run 1.6 seconds before you explode. If you hit a wall before that, you get tripped unless you are wearing the Halloween 2018X-Mas 2018, Easter or X-Mas 2019 version of the Ticker. If a Ticker hits a survivor while rushing, the survivor will get tripped.
Radiation (Passive): If a Ticker (or their radiation puddle) is close enough to a survivor, the survivor is dealt 1-3 damage per second depending on their proximity to the radiation source.
Tank Explosion (Passive): If a Ticker's tank is shot once, green gas is emitted. If shot again, the tank will explode, dealing damage towards the player who shot the tanks and zombies.



  • A Ticker can move backward with the intention for you to make them explode. Explosions instantly kill you at close range and push you back if the explosion is non-lethal.
    • Get a safe distance from them to then blow them up by shooting their tanks.
      • This still has some push, even if you're not hurt by the explosion. This can cause you to go in unprecedented ways and possibly take fatal damage not even from the explosion.
    • Knock it down with melee attacks and cleanly shoot their head until it dies.
      • This will make you take some radiation damage, however.
  • 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.
  • Ticker puddles take about 3-4 minutes to go away.
    • If impatient, you can easily take out the puddle with a Fire Extinguisher.
    • The Easter Variant has a cloud of gas that disappears more quickly but does more damage.
  • Shotguns and automatic guns are very dangerous to use around Tickers.
  • Those tanks could be your friend.
    • If there's a Ticker in the middle of a horde, shooting those tanks could easily wipe out the majority of the crowd.
  • After the Ticker's initial death, its tank can still be blown up by using an explosive on the tank, but only if the tank has not been exploded yet.
  • Shooting an Ice Gun, while a Ticker is rushing may not be a good idea, as once they fall to the ground, they explode.
  • Bringing a Flakvest is the best way to survive a Ticker rush.
    • The Bulldozer II armor will also survive the rush, but only at max health.
      • You will still be stunned using both vests, however. Being stunned can easily get you swarmed by other mobs and zombies, enforcing how important it is to stay with your teammates.
  • Watch out for radiation warnings! It might be a warning for a Ticker rushing at you.
  • The Fire Extinguisher completely nulls the effect of the Ticker's radiation if they are sprayed with it.
    • This allows you to safely melee the Ticker with no harm.
  • The Faraday Vest, Bulldozer I, Bulldozer II and Crab Armor can reduce the effects of radiation, but not completely null them.


  • Try to stay behind or under walls and ceilings. They can provide protection for you and you can damage survivors with radiation with ease.
    • If they blow you up then, the radiation pools left will drain their health twice as fast.
  • People can be affected by radiation, even through walls.
    • This is helpful if you want to try and weed out campers from their spots.
  • Tickers are slightly slower than the average zombie.
    • You have the same exact speed as a survivor, so chasing someone down isn't the best idea.
  • Having your back at a survivor at close range might end up the survivor shooting the tank, which will kill the survivor.
    • They do, however, have to be very close to you for them to die.
  • You will not get the 120$ for killing a survivor if your radioactive field or puddle kills them before you can damage them yourself.
  • Rushing to the Gas Tank in Campfire Chaos II or the Minecart in Zero Kelvin Station will deal a huge amount of damage on the survivors, as long as they're grouped together in one spot.
  • Only rush when you get a clean shot at exploding.
    • If you hit a wall before the 1.6 second timer is up, you will be tripped.
    • Jumping a couple of times before rushing can prevent you from overshooting too far.
  • The Ticker is banned on Outpost 21, don't bother trying to wait around for one.
  • If you touch SAFE-water when your bomb is ready then you explode. This does not work with KILL-Water, use to your advantage!
  • While you are rushing, you can trip and push survivors, similar to the Digger.
    • Use this to push off survivors near edges!
  • Using the Easter Costume for the Ticker can change the radiation pools into gas.
    • This can do more total damage than the puddle of radioactivity. However, it doesn't last for long.


  • This is the first zombie suggestion submitted by a user that was added to R2DA.
  • The Rush ability was nerfed in v1.2.8, whereby the damage for non-direct impacts was decreased.
    • This was further nerfed, requiring 2 seconds before exploding in v1.3.0.
    • This was later buffed so that you only require 1.6 seconds before exploding in v1.4.4.
  • The front of the Ticker became mesh, instead of drawn detail, in v1.1.6.
  • Presumably, this is the Boomer from the Left 4 Dead series, and the Ticker is Reason 2 Die: Awakening's counterpart.
    • Oddly enough, the puddles of radioactive waste may also relate to the Spitter from Left 4 Dead 2, as it drops a damaging patch of acid when killed.
    • Furthermore, after the rush was added into the game, this zombie is also similar to the Charger from Left 4 Dead 2.
      • In v1.4.4, the Ticker was given the ability to knock down players in its path, similar to the Charger when a survivor is caught in the charge.
  • Before v1.1.6, the Ticker used a Pinewood Emergency Team Hazmat Uniform, hence the emblem on the front of the suit in the first version.
    • The shirt was slightly different during the DEMO phase, with two radioactive symbols on both its shoulders seen in this picture.
  • Before v0.7.9, the explosion caused by shooting the Ticker's pack affected everyone in the blast range, but today, it will only affect the one who shot it and will also kill zombies near it.
  • Ticker puddles can fail to despawn and, after a new map is loaded, the puddle may still be around affecting everyone who goes near it.
  • The name of the Ticker is based on the sound the radiation makes when you get close to it with a Geiger Counter.
  • This zombie has affected gameplay with certain Mob Skincrates:
    • The Easter Costume has a different kind of radiation that makes players cough as if they made contact with a Wraith.
    • The Halloween 2019 Costume includes a riot shield which blocks bullets and a helmet that nulls the double damage trait from head-shots.
    • The Christmas 2018 Costume includes a drain feature for the tanks. When the tanks are drained, the Ticker explodes.
    • The Halloween 2020 Costume has a strange bug that makes you explode after hitting a survivor after 2 seconds of "Rushing", Use to your advantage.
      • This is most likely a Glitch, as it considers Survivors Collision's On, you also trip while stunning the survivor before 2 seconds
        • On some costumes, running into a wall before the timer runs out will not trip the Ticker.
          • This is more than likely a bug, however.
    • The Christmas 2020 Costume explodes and freezes survivors instead of radiation pools.
  • In the earlier stages of DEMO, zombies were able to damage the tanks on the Ticker, as seen below.
    • This glitch was accidentally brought back, only for Diggers, however.
