Call of Duty - Advanced Warfare - Biochemical Warfare

the Sentinels and the United States Army attack New Baghdad to stop Irons and bring him to justice. However, Atlas releases Manticore, killing most of the attacking troops except for Mitchell, Gideon and Ilona (whose DNA are recognized by Manticore as they are former Atlas soldiers) as well as Cormack who was outside the blast radius. The four are brought to an Atlas prison camp, which also runs Manticore experiments on its inmates. The Sentinels escape but Cormack succumbs to an injury caused by Irons, who also damages Mitchell's prosthetic left arm. As they escape the facility, they discover that Irons already has enough Manticore to attack every military base in the world, and will be launching a missile shortly.

With the fate of the world at stake, the Sentinels launch a final attack on Atlas' HQ. Mitchell and Gideon successfully stop the missile. They find Irons as the other Sentinels prepare to bombard the building. Irons disables their exoskeletal armour, forcing Mitchell to release the exoskeleton to chase Irons. An explosion throws Irons off the building, hanging on Mitchell's left arm. Mitchell severs his prosthetics, sending Irons falling to his death. However, even though Irons is dead, Mitchell notes that this was only the beginning, and the war against Atlas is far from over.
