New York City was a pre-War city in the United States.
Background
In 2065, a nuclear reactor, struggling to power the population of 17 million people, went supercritical for a period of about 5 minutes. While there was no explosion, the NYC incident coined the term "hot summer" for a heat-related electrical overload on nuclear systems.
New York was the location of the United Nations headquarters, before it was disbanded on July 26, 2052.
Dean Domino performed in New York City before the Great War.
Appearances
New York City is mentioned in the Fallout Bible 0 and also in a Capitol Post article about the disbanding of the United Nations in Fallout 3. It is also mentioned in the Fallout: New Vegas add-on, Dead Money.
