Master of the Mojave is an achievement/trophy and a challenge in Fallout: New Vegas which is awarded for successfully discovering 125 locations.
Notes
- Finding locations in add-ons will count towards this.
- The number of locations already discovered can be located under the stats tab in the Pip-Boy.
- The challenge that unlocks the achievement requires visiting 75 locations to be completed, which can mislead players, but this challenge only appears after completion of Walker of the Mojave, which requires discovering 50 locations.
