MARGOT

M.A.R.Go.T. (short for Metro Authority Rapid Governmental Transit System), also simply called Margot, is a computer system found in 2277.

Background
When approaching Margot, her voice will ask you to approach the console to identify yourself. After passing a very hard speech check, using your Science skill, or displaying the Senate Employee ID, you can gain more information and the nearby Sentry Bots and Mister Gutsys will no longer be hostile to you. Apparently Margot realizes that nuclear war broke out and 200 years have passed, but this is meaningless as she states that her primary function is to protect the Metro. She will also tell you about a breach in security caused by attackers who seem to have no body heat readings, and inform you that the fuse for the Metro needs to be replaced before you can use the train.

A nearby maintenance terminal in the metro will also mention that Margot originally had a male voice, but was changed to a female's voice during its development just so that the system could be given the acronym M.A.R.Go.T. as a name.

Occupation and activities
Having been in service since April 14, 2065, it watches over the Presidential Metro which connects the White House with The Capitol Building's East Wing and Adams Air Force Base.

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

Behind the scenes

 * The system was installed on April 14, 2065, which happens to be exactly 200 years after the real-life assassination of Abraham Lincoln.
 * M.A.R.Go.T. is an obvious nod to Portal's G.L.a.D.O.S.
