Mitchell accepts a 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. Mitchell, Gideon (Gideon Emery), and other Atlas operatives rescue the Nigerian Prime Minister and capture a KVA technologist in Lagos during an international summit. By 2055, Mitchell and his team fail to prevent a more sophisticated KVA from forcing a nuclear reactor meltdown on Bainbridge Island, Washington, near Seattle. The KVA launch simultaneous attacks against nuclear power plants worldwide, irradiating numerous cities and killing 50,000 people. Atlas emerges as the world's dominant military force 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 finds and kills Hades; before dying, Hades warns them of Irons and gives Mitchell a data chip. Atlas operative Ilona (Angela Gots) analyzes the chip. It reveals that Irons killed a defected KVA technologist after learning of the planned global attacks, and deliberately allowed them to happen to improve Atlas' power and profit. Irons attempts to have Mitchell and Ilona arrested by Atlas military police, but they escape Atlas' headquarters in New Baghdad, guided by an unidentified soldier, while Gideon stays with Irons for further investigation. The soldier reveals himself to be Cormack, now a member of the Sentinel Task Force, a Tier One global US-led task force created to investigate the KVA, but now re-purposed to prevent Atlas' 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 bio-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 attack the specific DNA of an individual and kill them; the only exceptions are Atlas members. Sentinel and Gideon infiltrate and destroy an Atlas bio-weapons laboratory in Bulgaria, destroying many Manticore samples. With his plan revealed, Irons declares war on
