Masterbrain

Masterbrain is a unique robobrain that controls all the other security robots in the Vault-Tec Headquarters in 2277.

Background
The Masterbrain was manufactured by Vault-Tec Industries to act a kill-switch for all other robotic security measures within the headquarters. It still remains active 200 years after the Great War.

Effects of player actions

 * If it is defeated and the player interacts with it, it will say "You have accessed the Masterbrain's internal mechanism. If you destroy its uplink, it will cause all the automated security units in Vault-Tec to shut down." If you do so, this will disable all other robots in the Vault-Tec Headquarters building, but not the automated turrets.

Other interactions

 * The player can shut down Masterbrain using 3 terminals scattered throughout the building. It is also possible to disable it using the Robotics Expert perk, if you have a high enough sneak skill, as Masterbrain will attack the player on sight.

Appearances
The Masterbrain only appears in Fallout 3.
