FIDO

FIDO is the upgraded K9000 cyberdog gun in the Fallout: New Vegas add-on Old World Blues.

Characteristics
Unlike the common K9000 cyberdog gun, FIDO uses .44 magnum rounds instead of .357 magnum rounds.

The brain case is red instead of green and the decal is changed from a golden retriever to a bulldog.

Just like the K9000, FIDO will bark when selected as the equipped weapon, and whimper when un-equipped.

Variants

 * K9000 cyberdog gun

Location
Inside the kennel in X-8 there are schematics for it, next to the terminal. Then take a K9000 cyberdog gun to a workbench to upgrade it.

Behind the Scenes
FIDO is an acronym referring to the archetypical dog's name "Fido", most famously associated with the name of Abraham Lincoln's dog. It is believed that this name was derived from the Latin word "fidelis" meaning loyal or faithful.

A canine companion has become a common theme throughout the Fallout franchise, such as:


 * Fallout: Dogmeat
 * Fallout 2: Dogmeat, Robodog
 * Fallout 3: Dogmeat
 * Fallout: New Vegas: Rex

In Old World Blues, the developers may have decided to humorously instead add a weapon with a dog's brain. See article entitled Dogmeat (Fallout 3) for more franchise fan information.
