- Call of Duty: Modern Warfare 3 is the third installment in Infinity Ward's first person shooter franchise. The much anticipated CoD: MW3 will begin right after Modern Warfare 2 left off and players will get to control a Russian Federal Protective Services agent, SAS Operative, tank gunner, and AC-130 gunner as well as other characters from previous games. The game will have about 15 missions, starting with the invasion of Manhattan by a Russian force
- The player assumes the role of various characters during the single-player campaign, changing perspectives throughout the progression of the story, which, like its preceedors, is divided into three sets of missions called "Acts". Each mission in an act features a series of objectives that are displayed on the heads up display. Mission objectives vary in their requirements, ranging from having the player arrive at a particular checkpoint, to eliminating enemies in a specified location, to standing their ground against enemy squadrons, manning mini-guns and other weapons, and planting explosive charges on an enemy installation. Some of these objectives can be failed, and may or may not hinder progression of the story. The player is also accompanied by fellow soldiers who cannot be issued orders.
- Modern Warfare 3 features a new mode, called Survival Mode. This game mode features one or two players fighting endless waves of enemies, with each wave becoming increasingly difficult. Despite being much compared to the World at War Nazi Zombies mode, enemies do not spawn at fixed locations like the zombies do; instead, they appear at tactical positions based on the current location of the player. The mode is available on all multiplayer maps in the game. Players earn cash for items such as weapons, upgrades, ammo, air/ground support and equipment. Special Ops also returns from Modern Warfare
