K9000 Cyberdog Gun

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

Background
The K9000 cyberdog gun was designed by researchers at the X-8 research center, although only two prototypes of the weapon were ultimately made. Following an incident in the X-12 research center involving Mr. Harris' death in a Y-17 trauma override harness, testing supervisor Dr. Adam Figgis gave away one copy of the gun to aid the response team, but they dropped it when confronted by the harness and were forced to leave it behind, where it fell into the harness' possession for the following centuries.

Personnel at the X-13 research facility were also given details about the weapon and attempted to help researchers at X-8 by creating modifications and upgrades for the weapon.

Characteristics
This weapon is actually an odd form of cyberdog, except instead of a robotic body in the image of a canine companion, a living dog's brain has been provided with a machine gun frame, utilizing .357 Magnum ammunition. Its "canine" features include two metallic "ears" mounted on top of the weapon that move like a real dog's and a sniffer 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 unequipped and 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 barrels reciprocate, rather than spinning like those of the 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.

Durability
The K9000 cyberdog gun can fire a total of about 2495 standard rounds, the equivalent of 50 reloads, from full condition before breaking.

 * One can be found in the X-12 research center, carried by the Y-17 master trauma harness (upgraded sonic emitter required).

Behind the scenes
K9 is a homophone for "canine," another word for dogs. This abbreviation is often used as a designation for police and military units specialized in using dogs.

Bugs

 * When using a Stealth Boy with the K-9000 cyberdog gun equipped, the brain case turns yellow.
 * There is a bug in the V.A.T.S. animation whereby it shows the weapon ejecting 12 spent cartridge cases instead of the correct number of 3. A close inspection of the damage dealt during one V.A.T.S. round will show that the weapon will deal the correct damage of 3 rounds and 3 rounds will be properly deducted from your inventory.
 * There is a bug that sometimes occurs after wearing it, the ammo pack will be stuck on your back. This can be fixed by restarting the game.
