The United States, full name The United States of America, commonly known as The U.S., The U.S.A, and simply America, was an ancient country located on the North American continent. Like every other country in the world of the Old Ones, the United States was destroyed and its people exterminated when the Faro Plague overran the planet and eradicated all life.
The United States played a key role in both in the ending of the Old World and the creation of the new one. Two tribes, the Nora and the Carja, live in what were then known as the states of Colorado and Utah, respectively. Colorado was the location of the robotics and technology corporation Faro Automated Solutions (FAS), which started what became the Faro Plague. The ruins of FAS are known in the new world as Maker's End.
The state was also the location of U.S. Robot Command, where the U.S. Joint Chiefs of Staff were briefed by the scientist Elisabet Sobeck on Project Zero Dawn, a plan to create a global terraforming system that would restore life to the planet after its eradication by the Faro Plague. The ruins of this facility are known in the new world as The Grave-Hoard. General Aaron Herres, Chairman of the U.S. Joint Chiefs of Staff, was responsible for devising and implementing Operation: Enduring Victory, a plan to give Zero Dawn as much time as possible to be implemented before life was eradicated. He also was responsible for procuring the world's most brilliant scientists and engineers as prospective candidates to work on Zero Dawn, and recorded a holographic presentation to the prospective candidates regarding the true nature of Enduring Victory and Zero Dawn. Additionally, Zero Dawn's staging area was located at Bryce Canyon, in Utah. The ruins of this facility now sit beneath the stronghold of the Shadow Carja tribe known as Sunfall.
Finally, Bashar Mati, an FAS employee, planted several time capsules known as Vantage Points throughout Colorado and Utah, memoirs of his life as the world of the Old Ones moved into its inevitable end due to the Faro Plague.
