Call of Duty is one of the most popular video game titles of all time and the most popular first-person shooter ever.

From humble beginnings in the shadow of Medal of Honor and Battlefield, Call of Duty has taken the FPS market by storm.

From realistic World War 2 battlefields, to the Cold War and then into space, COD has found its way into millions of homes across the world and helped the video game YouTuber boom in the early 00s.

With the latest title, COD has gone back to its roots, with ‘boots on the ground’ action again focusing on World War 2.

Not only is the game massively popular with casual players, but has been the backbone for Major League Gaming and has a highly competitive esports scene.
