MARGOT

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

Background
Having been in service since April 14, 2065, M.A.R.Go.T. watches over the Presidential Metro which connects the White House with The Capitol Building's East Wing and Adams Air Force Base.

Apparently M.A.R.Go.T. realizes something happened on the surface long ago, but is not sure what. In the end, what happened is meaningless to her anyway as her primary function is to protect the Metro and she will continue to do so until she is no longer able to.

A nearby maintenance terminal in the metro mentions 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, much to the annoyance of the maintenance worker who was given the responsibility of programming her new voice, a task implied to be somewhat onerous.

Quests

 * Who Dares Wins: When approaching M.A.R.Go.T., her voice will ask you to approach the console to identify yourself. After passing a "very hard" speech check, using your science skill, displaying the Senate employee ID, or using the Robotics Expert perk you can gain more information and the nearby sentry bots and Mister Gutsys will no longer be hostile to you. She will also inform the player that the fuse for the Metro needs to be replaced before the train to Adams Air Force Base can be used but will not allow the sentry bot with the replacement to be activated until the security breach is contained.

Effects of player actions

 * If you fail to identify yourself and M.A.R.Go.T. turns hostile, all of the robots in the Metro will remain hostile towards you.

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. may have been inspired by Portal's G.L.a.D.O.S.
