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
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.

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.

Effects of player actions
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, 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. Apparently Margot realizes something happened on the surface long ago, but isn't sure what. If the PC tells her that nuclear war broke out and 200 years have passed, she tells them that this is meaningless as her primary function is to protect the Metro and she will continue to do so until she is no longer able to.

She will also mention that there is a breach in security. She cannot tell anything about the attackers because she feels her sensors are malfunctioning since they are reporting the attackers as having no body heat readings and lethal radiation levels. She will also inform the PC 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. You then must head into the tunnels and contain the breach (kill all the feral ghouls), which will allow the Sentry Bot carrying the Fuses to repair the train line, allowing you access to Adams Air Force Base.

If you somehow fail to identify yourself and Margot turns hostile, all of the robots in the Metro will remain hostile towards you. You still must repair the Fuse box to continue to the Air Base, but know you must get pass several Sentry Bots, Misty Gustys, Turrets, and Feral ghouls to reach it.

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.
