Call of Duty Advanced Warfare for PS4 features Private Jack Mitchell of the United States Marine Corps, along with Private Will Irons and group leader Sergeant Cormack, participates in a battle against North Koreans in Seoul. During the counterattack, Will is killed in action, while Mitchell's left arm is severed, forcing him to be discharged from military service. After attending Will's funeral service, Mitchell is offered a position with the Atlas Corporation, the world's most powerful private military contractor, by CEO Jonathan Irons, Will's father. Mitchell is also given an advanced prosthetic arm to replace his lost one. Meanwhile, a terrorist group known as the KVA, led by a technophobic man named Joseph "Hades" Chkheidze, begins staging numerous terrorist attacks.
Now with the world turning to Atlas to stop them. Mitchell, along with Gideon, Joker and other Atlas soldiers rescue the Nigerian prime minister and later capture a KVA technologist in Lagos, Nigeria during a technology summit. However the KVA's attacks have become more sophisticated and Mitchell and his team fail to prevent the KVA from forcing a nuclear reactor meltdown on Bainbridge Island, Washington. The KVA launch simultaneous attacks against nuclear power plants worldwide, irradiating numerous cities, killing thousands of people and putting national governments and militaries in turmoil. Atlas emerges as the dominant military force in the world by aiding civilians affected by the attacks and holding back the KVA's rampage.
Later Mitchell and Gideon search an abandoned downtown Detroit only to find Dr. Pierre Danois, the KVA's second-in-command. After Ilona, an ex-Spetsnaz Atlas operative, interrogates the doctor, the team tracks Hades to Santorini, Greece, where KVA leaders are holding a conference. Mitchell corners Hades and fatally wounds him. With his last breath, Hades utters "Irons knows," and gives Mitchell a data chip. Ilona analyzes the chip, only to find out that Irons killed the technologist they captured in Nigeria after Irons learned of the KVA global attack, proving that he deliberately allowed the attacks to occur to improve Atlas' reputation and power. Irons attempts to have Mitchell and Ilona arrested, but they escape Atlas' headquarters in the rebuilt Baghdad.
