History of Call of Duty

Call of Duty is a first-person shooter video game franchise. The series began on Microsoft Windows, and later expanded to consoles and handhelds. Several spin-off games have been released.

The games use a variety of engines, including the id Tech 3, the Treyarch NGL, and the IW engine.
