Call of Duty: Advanced Warfare

Call of Duty (Sledgehammer games) was to be a new instalment of the Call of Duty series and would have been developed by Sledgehammer Games.

Call of Duty (Sledgehammer games) would have been of the action-adventure genre, however, unlike many action-adventure games, it would have been a first-person shooter.

The game was also rumoured to be an MMO, a first for the Call of Duty franchise, and was also rumoured to be subscription based.

In September 2010, Activision realized the community wanted another Modern Warfare game, or another game developed by Infinity Ward. In January 2011, it was confirmed the action-adventure game would be cancelled, or simply put on hold, and instead Sledgehammer Games is currently helping Infinity Ward with the Modern Warfare 3 campaign, while Raven Software works on the multiplayer.
