The action of Overwatch takes place in a technologically advanced, highly stylized future earth. In a time of global crisis, an international task force of soldiers, scientists, adventurers, and oddities known as Overwatch had come together to restore peace to a war-torn world. After many years, the group's influence waned, and it was eventually disbanded. Overwatch might be gone now . . . but the world still needs heroes.
