Winthrop

Winthrop is the maintenance man/chief engineer of Underworld. He maintains all things electrical or mechanical in the city, as well as the Mister Gutsy class sentinel robot named Cerberus.

Repeatable quest: This Old House
Due to a steadily declining supply of resources Winthrop requires Scrap Metal in groups of 5, in exchange for medical supplies (Stimpaks, RadAways or Rad-Xs.)

If you pass a Small Guns check (unknown skill - I had 77) you can threaten to kill him. After he protests tell him he will be long dead before help arrives. He will not be happy about this but will reward you with 10 Stimpaks, 10 RadAways and 10 Rad-Xs.

Appearances
only appears in Fallout 3.
