FIDO is a weapon in the Fallout: New Vegas add-on Old World Blues.
Characteristics[]
Compared to the original K9000 cyberdog gun, FIDO does more damage per shot and has the same rate of fire as the unmodified K9000, thus having a higher damage-per-second (DPS) value than it but lower than the modified K9000. It also does higher critical hit damage, costs slightly more AP, has higher spread, has the same weight and has a higher caps value than the unmodified, but lower than the fully modified K9000. It also has an 85 Guns and 9 Strength requirement, compared to the original's 75 and 8, respectively.
In terms of appearance, the gun frame remains the same but with a slightly lighter coloring; the blue tubing including the brain cage is instead red, and the sticker on the front display shows a snarling bulldog instead of a panting retriever.
Durability[]
FIDO can fire a total of about 2,495 standard rounds, the equivalent of 50 reloads, from full condition before breaking.

Location[]
The weapon cannot be found anywhere; instead, it must be crafted. This can only be accomplished once the requisite schematics are obtained from the X-8 research center. They are located next to the terminal in the kennels, which can be accessed after acquiring the key from the X-13 research facility, itself found in a security room off the front lobby. After acquiring the schematics, creating FIDO requires at least one K9000 cyberdog gun, 75 Guns, and use of a workbench.
Notes[]
- FIDO is the only automatic weapon in the game to use .44 Magnum rounds.
- The FIDO upgrade is best applied to an unmodified K9000 cyberdog gun, as using a K9000 to create the weapon will eliminate any and all mods the gun currently has.
- Regardless of the condition of the K9000 used to make it, FIDO will be created at 80% durability.
- As a total of two K9000s can be obtained in the game, it is possible to create two FIDOs.
- Despite being chambered in .44 Magnum, FIDO ejects bottlenecked rifle casings when fired.
Behind the scenes[]
The weapon's name is a reference to a famous dog of the same name, for which "Fido" then became an archetypical term for dogs, originated from the Latin word fidus, meaning "faithful."
