K9000 cyberdog gun

The K9000 cyberdog gun is a weapon in the Fallout: New Vegas add-on Old World Blues.

Characteristics
This weapon is actually a peculiar form of cyberdog; rather than a robotic frame in the design of a canine companion, a living dog's brain has been provided with a machine gun frame, utilizing .357 magnum ammunition. Its "K9 (canine)" features include two metallic "ears" mounted on top of the weapon that move like a real dogs, and a "curious nose sensor" mounted on the jar containing its preserved brain, allowing the gun to sense its surroundings. The metal ears also appear to move up and down faster if the gun is pointing in the direction of an enemy.

It will growl when the player has it equipped and comes into contact with enemies, whine (mournfully) when they un-equip it, and will bark when equipped. It also has, atypically for a machine gun, a telescopic sight (x2.43 magnification) which gives a relatively accurate aiming point and excellent precision in firing for a chain-gun type weapon. When fired, the three barrels reciprocate rather than spinning like those of a typical minigun.

The K9000 can also detect enemies out of visual and Perception range. When the weapon and its sniffer hover in the direction of an enemy for a few seconds, it will let out a detection growl, even at extreme range or when the enemy is hidden from appearing on radar.

The K9000 cyberdog gun can fire 2495 standard rounds or just short of 50 magazines from full condition before breaking.
