The Downtown part of Broken Hills has many buildings. There is the general store (run by Liz), the caravans office (owned by Bill), the bank and the prison (guarded by super mutants), the bar (the bartender is Phil), the power station (overseen by Brian) and the uranium refinery (run by the refinery supervisor).
Jacob the Chemist is looking for people who don't think mutants are friendly people... at all.
A powerplant makes electricity here, but some might want more power than others.
Broken Hills Downtown appears only in Fallout 2.
