It will be the third installment in the Modern Warfare series, a direct sequel to 2009's Call of Duty: Modern Warfare 2, and the eighth Call of Duty installment. It is set to be released on November 8, 2011 on Microsoft Windows, Xbox 360, and Playstation 3, with a separate version for Nintendo DS being developed by n-Space.

The player assumes the role of various characters during the single-player campaign, changing perspectives throughout the progression of the story. Each level is a mission that features a series of objectives that are displayed on the heads up display, which marks the direction and distance towards and from such objectives. Damage to the player is shown by blood shown on the screen. The player's health regenerates as time passes. Tasks vary in their requirements, having the player arrive at a particular checkpoint, eliminate enemies in a specified location, stand their ground to defend an objective, or plant explosive charges on an enemy installation. The player will be accompanied by troops who cannot be issued orders.
