Presidential Metro

The Presidential metro is a network of Metro tunnels that is added to Fallout 3 in the Broken Steel add-on.

Layout
It connects the Presidential Sub Level beneath the White House with Adams Air Force Base and The Capitol Building's East Wing. Protected and maintained by a computer system called M.A.R.Go.T., the area is guarded by sentry bots and swarming with ghouls. At higher levels, multiple feral ghoul reavers will be present.

Unmarked quest: Fatal Attraction
A holotape titled "Sorry, My Darling" can be found on a bench near the Capitol Building exit. The holotape kicks off the A Fatal Attraction unmarked quest.

Notable loot

 * Nuka-Cola Quantum in the Equipment Room, which connects the western and eastern lines.
 * Scoped .44 magnum at the top of a flight of rubble covered stairs. Dogmeat should be able to find it.
 * A police hat can be found near M.A.R.Go.T. in the room you first meet her.

Appearances
The Presidential metro appears only in the Fallout 3 add-on Broken Steel.

Bugs

 * Occasionally in V.A.T.S. mode, if you are standing near an npc or follower, upon exiting V.A.T.S., you may become stuck in the ceiling, and be unable to get back down. Reloading a save will fix this, or for PC users you can use console commands.
 * During battle with the ghouls the player may find some extraordinarily hard feral ghoul reavers which appear to be twitching uncontrollably. Because of this twitching they become almost impossible to hit, even in V.A.T.S. In such cases you should aim for their legs.
 * Occasionally when the Reaver is killed it may fling back down the hall where it came from. (Confirmed on PC on 2 separate playthroughs)(Very Rare in PS3)
 * Sometimes when using V.A.T.S. mode, the shots made from your gun will fly around and will not hit the target, regardless of the chance to hit them.
 * Every now and then when you have Fawkes with you he will glitch out of the train when you go to Adam's Air Force Base.(needs confirmation on PS3 and PC)(Confirmed on Xbox 360)

Behind the Scenes
The system concept and station design is based on the Capitol Subway.
