Cyber-factory

Cyber-factories were the facilities of cyber-conversion established by John Lumic's Cybus Industries across the seven continents of Earth in Pete's World. (TV: Rise of the Cybermen/The Age of Steel)

A London's Cyber-factory was located in London. It was Mickey Smith hacked into Cybus Industries' mainframe from Pete's World and located the code which all of the Cybermen's emotional inhibitors used (6879760) and texted it to Rose Tyler's mobile phone. The Tenth Doctor loaded it to the computer system. The code was shut down and the inhibitors turned off. All the Cybermen realised what they had become and died from the emotions they felt. John Lumic remained, having been converted into the Cyber-Controller, only to be lost in the destruction of the factory. (TV: The Age of Steel)

Soon after, a zeppelin was sent to the Paris' Cyber-factory in Paris where it transmitted the same code. It disabled that factory's emotional inhibitor. (GAME: Save Paris) In other cases, a Preacher was sent into the factory to destroy the inhibitor with his firearm. (GAME: Cyber Assault)

The Tenth Doctor noted that a Cyber-factory was located within the chest of the CyberKing, a humanoid Dreadnought-class ship, that was ready to convert millions. (TV: The Next Doctor)
