Using a Hydrogen cartridge and an Oxygen cartridge this underhand pistol generates its own water. The pistol also captures the energy released when the water is created and uses it to power a compressor which allows the water to be fired at a high velocity.
Additionally the pistol features an AWG (Atmospheric Water Generator) which captures water from the humidity in the air to subsidise the water created by the cartridges.
