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.
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 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, dangerous chemicals, and unstable construction of the Oxidizer, the position of pilot or gunner of one of these death traps is considered a lowly position, reserved for disciplinary action. The Oxidizer is designed purely for anti-aircraft warfare and so is very vulnerable to any other forces.
The Oxidizer makes its first appearance in Ghost Hunt, among the Scorpion Cell enemies.
