How many people play Call of Duty?

Answer 1

I could not find an exact number but even though it is an older game don't be surprised at how many people still play online, especially because it is part of the Call of Duty franchise, so if you are looking for someone to play online don't worry because there are still plenty of people who still play the game.

Answer 2

In all consoles, about 4.5 million

but since ghosts came out many people left the game because the game became worse than it used to be .(one of the guys that left are Optic clan)
