It is a Plasma caster which is fired from the shoulder of the Yautja and it fires a plasma pulse, not bullets.

Plasma caster

The plasma caster is a shoulder-mounted energy weapon. A triangular laser rangefinder is used to assist aiming the shot. The laser sight can be part of the Predator's helmet, although some casters have their own laser sights without need of a helmet. In both set-ups the plasma caster moves with the Predator's field of vision. It fires a bright blue or gold plasma pulse in a straight line. The pulse can be controlled to fire with more powerful charges ranging from minor stunning/wounding blasts or powerful enough to sunder the atmospheric plating of interstellar aircraft. The plasma caster and respective tracking servos are some of the most vulnerable articles of equipment carried by the Predator, being easily damaged. The plasma caster can also be used as a hand held weapon.

  • You may also want to cut n paste in the bit about it also being called a "Plasma Cannon,[2] Laser Cannon[3] or Shoulder Cannon,[4][5]" along with the sources of that info

  • @Valorum, the only canon name was the Plasmacaster was it not?

  • It depends what you mean as canon. The term "Plasmacaster" comes from a computer game whereas "Plasma cannon" is what the cast/crew called it in the "Making of Predator 2: Weapons of Choice" special feature on the DVD, "Laser Cannon" is what they called it in one of the authorised novels

  • "Shoulder Cannon" comes from one of the games and a "making of" featurette from AVP: Requiem.
