FIDO

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

Characteristics
Unlike the K9000 cyberdog gun, FIDO uses .44 magnum rounds instead of .357 magnum rounds, resulting in higher damage and a slightly higher spread. The brain case and the scope are red instead of green and the decal is changed from a golden retriever to a bulldog. Other features of the K9000 cyberdog gun are included in FIDO.

Durability

 * FIDO can fire a total of about 2495 standard rounds, the equivalent of 50 reloads, from full condition before breaking.

Variants

 * K9000 cyberdog gun

Comparison
While in terms of base statistics the FIDO is better, the K9000 cyberdog gun is fractionally better with the Mentat Chow mod, and significantly better with both that mod and the Resla Roil (DPS: 274.4 or DPS-reload: 175.95).

Location

 * The schematics for FIDO are located in X-8 research center, next to the terminal in the Kennels. After acquiring the schematics, take a K9000 cyberdog gun to any workbench to upgrade it into FIDO. The process requires a Guns skill of 75.

Behind the scenes

 * The name FIDO refers 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.
