DESCRIPTION:

CALL OF DUTY 8 : Modern warfare III

Campaign

The player assumes the role of various characters during the single player campaign, changing perspectives throughout the progression of the story, which, like its predecessors, is divided into three sets of missions called "Acts". Each mission in an act featuring a series of objectives that are displayed on the heads up display, which marks the direction and distance between such objectives and the player. Damage to the player is shown by the visualization of blood-spatter or red-outs on the screen. The player's health regenerates over time as long as the player character avoids from taking damage for a limited time. 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, directing remote-operated weapons, and planting explosive charges on enemy installations. The player is also accompanied by fellow soldiers who cannot be issued orders. Like its predecessor, the game includes an interactive scene of a terror attack against civilians, which the player is given the option of skipping due to the portrayal of graphic and potentially upsetting content, including harm to children.

Cooperative

Modern Warfare 3 features a new mode, called Survival. This mode allows between one and two players to fight endless waves of enemies, with each wave becoming increasingly difficult. It differs from the Nazi Zombies mode in Call of Duty: World at War, principally in that enemies no longer spawn at fixed locations like the zombies do, but instead 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 in-game cash for items such as weapons, upgrades, ammo, air/ground support and equipment. Special Ops also returns from Modern Warfare 2. These challenge missions feature up to 48 stars, unlike its previous installment, which featured 69. Some weapons in Spec Ops are exclusive to that game mode, and are not available for play in Multiplayer mode.

Special Ops

The Special Ops game mode from Modern Warfare 2 is present in Modern Warfare 3, and includes new features which make it more replayable and similar to other game modes, such as Nazi Zombies from previous Call of Duty games, and Hordes from Gears of War. The two main Special Ops modes include one that is generally the same from the last Modern Warfare game, and a new wave based game, Survival, where the player is inserted into a multiplayer map alone or with a single partner and defends an area against waves of enemies. The players can buy support options unlocked with XP earned during each round.
