Overwatch is set sixty years into the future of a fictionalized Earth, thirty years after the resolution of the "Omnic Crisis". Prior to the Omnic Crisis, humanity had been in a golden age of prosperity and technology development. Humans developed robots with artificial intelligence called "Omnics", which were produced worldwide in automated "omnium" facilities and put to use to achieve economic equality. The Omnic Crisis began when the omniums started producing a series of lethal, hostile robots, which turned against humankind. The United Nations quickly formed Overwatch, an international task force to combat the omnic threat and restore order.
