The most recent title, Modern Warfare 3, reached a billion dollars in sales faster than any entertainment product before on it release last November.

The game, the ninth in the Call of Duty franchise and the follow-up to the first Black Ops title, released in 2010, will be available from 13 November, Activision said. Halo 4 will be released on 6 November.

Activision CEO Eric Hirshberg said the new Call of Duty game would be "taking some risks". 

"There's a lot of new ideas. We are going for it," he said.

Activision will hope that moving the franchise into a futuristic setting will reinvigorate gamers' interest. The script has again been written by David Goyer, best known for the screenplay for Batman Begins.
