The Oxidizer is a support anti-air vehicle used by the Scorpion Cell. Despite being classified as such, it does no damage to enemy aircraft whatsoever, but instead makes them more susceptible to damage.

Official description

The Oxidizer is the Scorpion Cell's dedicated anti-air support system. Oxidizers are primarily made up of salvaged parts of other vehicles, haphazardly soldered and bolted together in order to cut down on costs taxing the Cell's fluctuating budget. The resulting contraption is capable of moving on water with help of simple suspension materials, and fires capsules containing a highly potent cocktail of hydrogen peroxide, hydrochloric acid, and nitric acid, which literally eats away at aircraft.

Due to the threadbare interiors, a dangerous mix of chemicals used, and a rather unstable construction of the Oxidizer, the position of pilot or gunner of one of these death traps is considered a lowly position among the Scorpion Cell forces, reserved usually for disciplinary action. The Oxidizer is designed purely for anti-aircraft warfare and so is very vulnerable to any other forces.[1]


Oxidizer is a special Tier 3 unit used by Scorpion Cell to reduce the defense of enemy air units. This feature makes it often used in conjunction with the Gatling Tank and turn this team into "advanced anti-air defense unit". Even better, they have the same speed, which means that this combination can also be used for guerrilla.

The biggest weakness of Oxidizer is that the armor is extremely weak. Due to this, Scorpion Cell commanders are more accustomed to using them and the matching Gatling Tank/Gatling Cannon for defending their base and sending them into the Tank Bunker.

AI behavior

Oxidizers controlled by the AI have the following attack patterns:

All difficulties

  • 1x entering Tank Bunker
    • This task force may be accompanied by 1 additional Oxidizer
  • 2x guarding Gatling Cannons, Inferno Towers and Radar Spires, accompanied by 4 Archers and 2 Gatling Tanks


Our new Oxidizers can make enemy air units more vulnerable to damage.

Special Ops


  • Weapon decrease target aircraft's armor by 25%.
  • Armor debuff is stackable, allowing anti-air weapons to shoot down heavier aircraft with ease.
  • Very effective against aircraft.
  • Can fire on the move.
  • Fast.
  • Amphibious.
  • Reasonably inexpensive for an high-tier vehicle.
  • Cannot sink if disabled while waterborne.
  • Lightly armored.
  • Cannot deal direct damage.
  • Useless against ground units and needs support to deal with air units.


  • As there appears to be no limit to the stackable armor debuffs, several Oxidizers (at least 10 or more) targeting the same air unit will cause even certain, normally harmless effects to become lethal.
    • For instance, a Black Widow's armor boost to friendly aircraft (or Sensor Tower's spotlight) is able to destroy the most durable air units with enough Oxidizers. This is because the buff or debuff from such units/defenses deal 1 damage to the target in order to apply said buff/debuff. The mass Oxidizers increase this damage value up to the point where it can cause actual damage.
    • A demonstration of this can be found here.
