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 to a bulldog. Other features of the K9000 cyberdog gun are included in FIDO.

FIDO can fire a total of about 2,495 standard rounds, the equivalent of 50 reloads, from full condition before breaking.

Location
The schematics for FIDO are located in X-8 research center, next to the terminal in the kennels, which can be accessed after acquiring the key. The key can be found in a security room off of the front lobby of the X-13 research facility. After acquiring the schematics, taking the K9000 cyberdog gun to any workbench will allow it to be upgraded into FIDO. The process requires a Guns skill of 75.
Notes
- FIDO is the only automatic weapon in the game to use .44 Magnum rounds.
- The upgrade is best applied to a K9000 cyberdog gun without mods, as applying the update will eliminate all mods the gun currently has.
- Regardless of the K9000 condition, FIDO will be at 80% durability.
- K9000's mods cannot be equipped to FIDO.
- As a total of two K9000s can be obtained, one can therefore obtain two FIDOs.
- Despite being chambered in .44 Magnum, FIDO will eject bottlenecked rifle casings when fired.
Behind the scenes
The name FIDO refers to the name of a famous dog, the name of which subsequently became archetypical, meaning "faithful," from the Latin fidus.
