The year is 2054, and the world has suffered an attack on its militaries around the world. The largest military force in the world isn't a country, but a corporation. Private Mitchell (Troy Baker) carries out missions for Jonathan Irons (Kevin Spacey), the leader and founder of Atlas, the largest private military firm in the world. Irons begins a war with America over his beliefs that the U.S., for over a century, has failed numerous attempts to install democracies all over the world.
