New Phoenix

New Phoenix is a metropolitan area of Arizona, a state in the United Republic of North America on Earth.

Battle of Earth
During his swift attack on Earth in July 2557, the Didact was able to position his flagship, Mantle's Approach, in a high geosynchronous orbit above the city. Despite resistance from the UNSC Home Fleet, he activated the Composer, converting New Phoenix's population into "digital intelligences" and disintegrating their bodies. Spartan John-117 soon destroyed the Composer, presumably freeing the digital remnants of New Phoenix's residents from the Didact's thrall.

Due to the nature of the Composer, the city's infrastructure remained completely intact. New Phoenix was quarantined after the holocaust and remained off-limits for at least six months. John Sullivan, an Office of Naval Intelligence public relations officer, released a statement that the attack was not of Covenant origin.

Trivia
New Phoenix is the first North American city to be visually depicted in the story of a Halo game and is the fifth overall, after the Kenyan cities of New Mombasa and Voi, the Ecuadorian city of Quito, and the Australian city of Sydney.
