"Overwatch" is set sixty years into the future of a fictionalized Earth, thirty years after the resolution of the "Omnic Crisis". Prior 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.
Did You Know? To develop "Overwatch's" themes, director Jeffrey Kaplan stated they wanted to create a future that was not typical of what a post-apocalyptic world might be like, opting instead for a future where conflict still exists but a "bright and aspirational vision" is maintained.
