The Hydro-Jet Cannon is a fully automatic firing variant of the Gas Cannon, and takes an equivalent set of variable ammunition types. Compared to the Gas Cannon, the Hydro-Jet ammunition trades off lower power for a greater ammunition supply and a slow three-round auto firing mode. The Hydro-Jet Cannon can only be operated underwater.

The Hydro-Jet Cannon loads three types of ammunition. Armour Piercing, High Explosive and Phosphor.

The Hydro-Jet Cannon is generally low in accuracy, but makes up for it in volume of fire. It is as fast to fire as the Jet-Harpoon in snap and auto modes, but can deal significantly more damage. It is not designed for accurate snap or aimed shots.

The weapon and its ammo belts are large and heavy, though the larger ammo capacity means that fewer spare clips are needed.

The Hydro-Jet Cannon is a very destructive weapon and can be used to great effect in close quarter combat, particularly when better protection is available. However, the underwater-only limitation requires extra micromanagement of equipment to ensure that alternate weapons are made available to the Aquanauts during land based missions.

This weapon appears in Terror from the Deep. For the UFO: Enemy Unknown equivalent, refer to the Auto-Cannon.

Pros Cons
  • Moderate power

Notes

  • As the reaction fire mechanism is not aware of the under-water restriction, underwater-only weapons can be fired on land via reaction fire.

Recommendations

When visiting land missions, be sure to swap these weapons out with weapons that can be fired on land. Either swap them out, or bring spare weapons.

It is not recommended that you arm the entire squad with this weapon. In the event you have to attend a land based attack, or your base is attacked, you will not be able to fight back. At least not fight back under normal circumstances.

Consider carrying this weapon with Phosphor rounds for illumination use at night (or on Alien Colony Assaults) to conserve the limited item space aboard the transport. Each clip of Phosphor rounds can illuminate 14 areas on the map, albeit only briefly.
