Explorer (Fallout: New Vegas)

Explorer is a perk

Effects
Every location in the Mojave Wasteland is revealed on the map.

Bugs

 * Sometimes, when you take the perk, no location will be revealed.
 * You can level up high enough to choose the Explorer perk before leaving Goodsprings for the first time by using the infinite XP exploit with Doc Mitchell or Chet. Then, when leaving the town you can rebuild your character. The Explorer perk won't be available because you've already taken it, however, all the markers will remain on your map. You can then choose any perk instead of having to choose the Explorer perk.
