Explorer

Explorer is a Fallout, Fallout 2, Fallout 3 and Fallout Tactics Perk.

Fallout, Fallout 2 and Fallout Tactics
The mark of the Explorer is to search out new and interesting locations. With this Perk, you have a greater chance of finding special places and people in random encounters.

Fallout 3
When you choose the Explorer perk, every location in the world is revealed on your map.


 * It should be noted that this doesn't allow you to fast travel to any of the locations it reveals, and doesn't add them to your Geomapper Module for the Geomapping with Reilly quest. This makes this perk somewhat useless, as you can simply look up locations on any online map, and save your level 20 perk slot for something better, such as Grim Reaper's Sprint, which can only be obtained at level 20.
 * The Broken Steel Add-on though makes this perk much less useless as the levels now go to 30. You can now take Explorer without sacrificing any of the level 20 perks.
 * This perk may be a good idea to help with the One-Man Scouting Party achievement.
 * The collectors edition guide has this perk as allowing you to fast travel to all the locations the reason for this error could be the same as why Barkskin is also wrong in the guide.
 * It should be noted that the enlisting of this perk will not reveal the additional locations provided by DLC such as Broken Steel or The Pitt.

Bugs

 * On my PS3, I used the explorer perk when I reached level 20. I then went back to a previous save, and all the locations unveiled by the Explorer perk were still there, while I was only on level 19
