In every Call Of Duty to date, there is a secret weapon that serves as the base for all weapons called "Default Weapon." It cannot be obtained legitimately, and can only be equipped through console commands.
The original code name for the Call of Duty franchise was "Medal of Honor killer", as Medal of Honor was the most prominent first person shooter during Call of Duty's development.
The Colt M1911 .45 is the most featured weapon in the Call of Duty series. It has been in every game except Call of Duty: Finest Hour and Call of Duty: Black Ops: Declassified.
The franchise has earned over $4.7bn USD in revenue, more money than can be found in the entire country of Nicaragua
