Cerberus

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

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

Relationships
serves the Ghouls in Underworld.

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

Interactions with the player character
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."

With the Robotics Expert perk, the player can remove Cerberus's combat inhibitor, 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 loses, or Cerberus may slaughter the lot of them. A good idea if you don't want to fight him you can take some Stealth Boys or use the Chinese Stealth Armor and then, enjoy the show!
