- "Seat of the UNSA and home to the majority of the solar system's population. Also the primary client of mining and industrial operations system-wide. Despite terraforming efforts on Mars, this remains the only planet hospitable to life."
- — Description
Earth is a planet in the Solar System. In Call of Duty: Infinite Warfare, it is the primary seat of the United Nations Space Alliance's power, as well as the source of most of the Solar System's population.
By the time of the game, Earth has been stripped of most of its natural resources, prompting the colonization of other worlds within the system. The planet's planetary defense system was hijacked by an SDF sleeper agent during the annual Fleet Week Parade in Geneva, destroying the SATO fleet.
Earth-bound nations that make up the UNSA include Canada, France, Germany, Ireland, Japan, Lebanon, Mexico, Nigeria, Norway, Sweden, Russia, Spain, Switzerland, the United Kingdom and the United States.
