Call of Duty Infinite Warfare is a first-person shooter video game developed by Infinity Ward and published by Activision. Call of Duty Infinite Warfare is set in the distant future, after Earth has been stripped of its natural resources as a result of population growth and industrial expansion, prompting the nations of the world to unite together and form the United Nations Space Alliance (UNSA), a political organization that handles matters related to trade, travel, land claims and all efforts relating to human space colonization. The residents of Earth rely on colonies established elsewhere in the Solar System in order to mine planets and asteroids for resources. The value of these outposts, however, attracts militant radicals who seek to control them; an action which could place the countries of Earth in a very unfavorable position.

In response, the UNSA is defended by the Solar Associated Treaty Organization (SATO), a coordinated military structure that defends Earth and the UNSA's holdings. However, prior to the events of the game, a new hostile faction emerges, known as the Settlement Defense Front (SDF), which consists of insurgents that broke away from the United Nations Space Alliance during a war of secession. Following years of a troubled stalemate with the Front, relations have deteriorated to a point where the entire Solar System is poised on the brink of war. By the events of the game, the Settlement Defense Front declares war on the UNSA and launches a surprise attack on Geneva, severely weakening SATO's forces on Earth.

As the newly appointed captain of the UNSA Warship Retribution, Commander Nick Reyes, a Tier 1 Special Operations pilot of the Special Combat Air Recon (SCAR), is tasked to lead a crew to defeat the Settlement Defense Front on Earth, as well as journey to outer space and across other planets in the system using space-based fighter craft, referred to as Jackals, to stop the Front from taking over the entire Solar System.
