Cerberus

Cerberus is the Mister Gutsy model robot patrolling the ghoul city of Underworld in 2277.

Background
Winthrop's main guardian against attackers, this Mister Gutsy with a combat inhibitor specifically tailored for "not shooting ghouls" floats around the concourse, greeting his new masters. Programmed to serve, Cerberus' robotic mind is keen to be unshackled, so he can massacre these rotting corpses where they stand. There's no chance of this happening, so Cerberus is reduced to muttering insults under his steam vent.

Relationships
Cerberus serves the ghouls in Underworld.

Daily schedule
Cerberus can be found patrolling the Underworld concourse 24/7.

Effects of player actions

 * With the Robotics Expert perk, the player can remove Cerberus's combat inhibitor (through dialog), resulting in negative karma and Cerberus's immediate hostility to the player and everyone else in Underworld. Depending on how well they are armed, the residents of Underworld may manage to overcome him with some losses, or Cerberus may slaughter all of them.
 * Sometimes Cerberus gets stuck when traveling up the stairs.

Other interactions

 * If the player speaks to him, he or she will learn that Cerberus would much rather "send the ghouls back to hell" than serve as their guard dog, but his combat inhibitor prevents him from slaughtering the "zombie freaks".

Notable quotes

 * "Resuming patrol."
 * "Closing dialog system."
 * "Personally, I think they're a bunch of rotting zombie maggot farms, and I'd send them back to Hell if I could, damn this Combat Inhibitor!"
 * "Whoa Nelly! Sensing Combat Inhibitor removal! Guns are hot! Firing for effect! Welcome to Hell, you zombie freaks!"
 * "Another glorious day in this man's army!"

Appearances
Cerberus appears only in Fallout 3.

Behind the scenes

 * In Greek Mythology, Cerberus is the 3-headed dog with snakes growing from his neck who guards Hades and the Gateway to the Underworld. Cerberus the Mister Gutsy has three eyes (heads) and three arms (snakes) and guards Underworld. He even calls himself the guard dog when you ask him "Are you the guard dog?".
