The "Overwatch" game is based on the future of the Earth, telling the grievances of human beings, watch pioneers and intelligent machinery. The game currently has 28 heroes, each with its own iconic weapons and skills. In the early 1920s, humans designed intelligent machines (referred to as intellectual devices) created by artificial intelligence, which aims to strengthen production and create world economic prosperity. However, incredible things have happened, and the mentally-armed devices have become malicious and have begun to mass-produce military robots to try to destroy humanity. Governments failed to stop the attack of intelligent machinery, so the United Nations created an international peacekeeping organization to resist intelligent machinery. The organization that brings together the best and most elite organizations in the world is named "Watching Pioneer", which will launch an asymmetrical war around the robot army.
