Complete story — includes the ending
In 2054, U.S. Marine Jack Mitchell (Troy Baker) and Will Irons (Paul Telfer) help repel a North Korean invasion of Seoul, under the command of Sergeant Cormack (Russell Richardson). During the fight, Will is killed in action and Mitchell loses his arm, resulting in him being medically discharged. Following Will's funeral, Mitchell accepts a job position at the Atlas Corporation, a private military corporation, by its CEO, Jonathan Irons (Kevin Spacey), Will's father, and is given a prosthetic arm.
A terrorist group called the KVA, composed of former Chechen separatists led by Joseph "Hades" Chkheidze (Sharif Ibrahim), begins staging attacks. In 2055, Mitchell, Gideon (Gideon Emery), and other Atlas operatives rescue the Nigerian Prime Minister and capture a KVA technologist in Lagos during an international summit. However, Mitchell and his team are later unable to prevent a more sophisticated KVA attack from forcing a nuclear reactor meltdown on Bainbridge Island, near Seattle. The KVA launches simultaneous attacks against nuclear power plants worldwide, irradiating numerous cities and killing 50,000 people. Atlas emerges as the world's dominant military force over the next four years by aiding displaced civilians and repelling the KVA.
In 2059, Mitchell and Gideon are dispatched to Detroit to find and capture Dr. Pierre Danois (Erik Passoja), the KVA's second-in-command. Danois reveals that Hades is at Santorini, Greece, where the KVA is holding a conference. In Greece, Mitchell kills Hades; before dying, Hades warns them of Irons and gives Mitchell a data chip. Atlas operative Ilona (Angela Gots) analyzes the chip, which reveals that Irons executed the technologist after learning of the planned global attacks, and deliberately allowed them to happen to increase Atlas' power and profit. Irons attempts to have Mitchell and Ilona arrested by military police, but they escape from Atlas' headquarters in New Baghdad with an unidentified soldier guiding them, while Gideon stays with Irons for further investigation. The soldier reveals himself to be Cormack, now a member of the Sentinels, a Tier One US-led global task force created to investigate the KVA but now re-purposed to prevent Atlas's rise to power.
In 2060, Mitchell, Cormack, Ilona, and Knox (Khary Payton) infiltrate Irons' private residence in Bangkok. The team discovers that Danois is collaborating with Irons to produce a biological weapon called "Manticore". They track and intercept a plane carrying Manticore bound for Argentina, which crashes in Antarctica. Gideon helps the Sentinels defeat the Atlas soldiers, allowing them to retrieve a sample of Manticore. They discover that the weapon is designed to target and kill an individual's specific DNA; the only exceptions are Atlas members. The Sentinels and Gideon infiltrate and destroy an Atlas bioweapons laboratory in Bulgaria, destroying many Manticore samples. With his plan revealed, Irons declares war on the United Nations General Assembly, blaming their constant warmongering for his son's death and believing that the world would be better off if Atlas were in control. The team discovers that Irons is planning a preemptive strike on the United States via an Atlas attack in San Francisco. Atlas destroys the Golden Gate Bridge, trapping the United States Navy's Third Fleet in the Bay Area, but is stopped by Sentinel forces. The United States and the rest of the world declare war on Atlas, forcing Irons to retreat to his headquarters in New Baghdad.
In 2061, the Sentinels led an attack on New Baghdad to capture Irons. However, Atlas deploys Manticore, killing Knox and most of the troops. Being former Atlas soldiers, Mitchell, Ilona, and Gideon are spared. They and Cormack are captured and brought to an Atlas prison camp, which runs Manticore experiments on its inmates. The team escapes the facility, but not before Irons shoots Cormack and severely damages Mitchell's prosthetic arm. After Cormack dies, the others discover that Irons is preparing to launch ICBMs loaded with Manticore against every military base in the world. Using armored battlesuits, Mitchell and Gideon launch a two-man assault on Atlas' headquarters and destroy the missiles. They find Irons as the other Sentinels prepare to bombard the building, but Irons disables their exoskeletons. Mitchell chases and tackles Irons at the edge of the building; Irons hangs onto Mitchell's prosthetic arm, but Mitchell severs it, sending Irons falling to his death. Gideon pulls Mitchell from the ledge, and Mitchell notes that the war against Atlas is far from over.
