Masterbrain

Located in Vault-Tec Headquarters,  is a unique Robobrain that controls all other security robots in that facility. The player can shut down Masterbrain using 3 terminals scattered throughout the building, in effect disabling security. Masterbrain will attack the player on sight. It is the only known Robobrain without a visible brain. As it would be a vulnerable target, Masterbrain's brain is likely armor plated, or alternatively, may be entirely cybernetic.
