Call of Duty: Black Ops III takes place in 2065 in a world facing upheaval from climate change and new technologies. In response to the drone assaults of Black Ops 2: several countries around the world have developed high-tech air defenses that render conventional air forces virtually useless. As such most of the warfare between countries is done by covert operatives fighting behind enemy lines. Military technology has progressed to the point where robotics play a major role in combat and both fully robotic humanoid drones and cyborg supersoldiers have been developed to fight in the battlefield.
