MARGOT

Margot is a computer system in the Fallout 3 DLC Broken Steel. It watches over the Presidential Metro Line under the remains of the White House.

Margot stands for "Metro Authority Rapid Governmental Transit System".

When nearing Margot, her voice will ask you to approach the console to identify yourself. After passing a check via speech options (it helps if you have a high science skill) you can gain more information and the sentry bots will no longer be hostile to you. Apparently Margot realizes that nuclear war broke out and its 200 years later, but this is meaningless as she states that her primary function is to protect the Metro. She will also tell you about the attackers which 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.

Appearances
appears only in the Fallout 3 DLC Broken Steel.

Trivia
MARGoT is a reference to the video game Portal, in which the silent protagonist must use a portal gun called the Aperture Science Handheld Portal Device to survive several " scientific tests" (that are actually dangerous challenges to test the guns potential) in an abandoned facility. The creature forcing the protagonist to carry on is an A.I. named GLaDOS (General Lifeform and Disk Operating System. Due to the similarities (their names and the fact that they are both artificial intelligences), one can think of MARGoT as an homage to the GLaDOS character.
