Most Wanted

Most Wanted is an unmarked side quest in Fallout: New Vegas. As of patch 1.4.0.5xx it is now a component of the larger Faction Hit-Squad Master Quest, along with the anti-Legion quest Caesar's Foe.

Overview
Most Wanted is the name given in the GECK editor to the quest which controls the appearance of a hit squad comprised of NCR troopers and/or NCR rangers. Should the Courier's negative reputation with NCR reach a certain point, this hit squad will be dispatched to kill them. As of patch 1.4.0.5xx, this quest has been dismantled and replaced with "Faction Hit-Squad Master Quest", with the same in-game function.

A "warning" squad is dispatched within hours of the Courier first attaining a sufficiently negative status with the NCR, warning them that if they do not improve their standing they will be treated as an enemy. Thereafter, assassins are dispatched approximately every three days, depending on whether or not the Courier is located in an area where they can be attacked.
