Mini-FOT LogoThe following is based on Fallout Tactics and some details might contradict canon.

C-27 Series[1] humanoid robots are a type of robot utilized by the Calculator in 2197.


Created by the Acme corporation before the Great War, C-27 Series humanoid robots are the main work force for the Calculator. As the name states, they are bi-pedal, two armed robots, about the size of a large man. Due to budget cutbacks by the Department of Defense (because of a false sense of safety as a result of the repeated drills) for Vault 0, several important backup systems were not included to the neuro-link systems.

This resulted in the corruption of the Calculator and instead of releasing the robots to make the Wasteland safe for humanity (it appears to be designed to adapt to human technology and weaponry), the robots manufactured from Vault 0 used its arsenal and anywhere else that sufficient armament could be found, to exterminate all life, completing the so called "pacification protocol". It can use most normal human equipment, with any sort of RS-231.5 interface required by most robotics.

The C-27 Series humanoid robots are devastating war machines built from pre-War technology. They have high damage capacity, including most resistances but are especially vulnerable to EMP weapons. They never get perks, but get an extra 5 skill points per level.

Interactions with the player characterEdit

Interactions overviewEdit

Effects of player's actionsEdit

After the end of Fallout Tactics, the Warrior destroys the Calculator and disables all humanoid robots. The only possible survivor is HR 1205, a humanoid robot reprogrammed by the Brotherhood of Steel.

However, depending on the ending, the Warrior's or Barnaky's brain (when merged with the Calculator) creates and/or restores several humanoid robots to help the Brotherhood, going by the various ending slides which shows the Brotherhood of Steel working alongside humanoid robots.

However, should the Warrior fully destroy the Calculator, no such robots appears in the ending slides.

  • Humorously, a robot in Newton between the general's office and science lab sleeps, emitting a "Zzzz" sound.
  • One robot in Vault 0 is friendly, standing near a citizen's body with the severed head.
