Poinstreaks can now be earned for completing objectives in any objective mode, or by shooting down enemy air support. In previous games, Killstreaks could only be earned by killing other players. A player picks one package and selects three rewards from it. There are now three Pointstreak packages. The Killstreak system is now called the Pointstreak system and it has changed very much. If a player has reached Prestige 20, they can spend a Prestige Token to reset all statistics to level 0, Prestige 0. The first time it is done, the player will be on Prestige 1, and so on. This resets all the player's weapons, perks and pointstreaks. Players can enter Prestige mode once they complete level 80. They also unlock new titles and emblems, and they increase their multiplayer rank until the limit of 80. As the player does more, they unlock new weapons, attachments and perks. Players can play different game modes in a variety of maps. Players can do the multiplayer mode online or locally. The multiplayer is similar to that of Modern Warfare 2. One or two players can do Survival, Chaos and most Missions. Weapons are scattered around the map, and perks and care packages assist the players. Players must earn the most money they can, which is done by keeping the multiplier going and killing as many enemies as possible as quickly as possible. This is so the player has time to buy weapons, explosives and Pointstreaks. There are thirty seconds between each wave of enemies. There is no way to complete Survival mode because the waves keep coming. In the Survival mode, waves after waves of enemies attack the player/s. In the Mission mode, players do lots of different missions and get stars for their work. The Mission mode is a game mode that comes back from the special ops mode of Call of Duty: Modern Warfare 2.

There are three parts to the special ops mode: the Mission, Survival and Chaos modes.

The characters include people from previous games in the Modern Warfare series such as: John "Soap" Mactavish, Captain Price, Makarov and Macmillan. Russia continues its invasion of the United States of America and expands its attack to Europe, including the coutries England, France and Germany. The campaign follows the events of Call of Duty: Modern Warfare 2. There are three main sections to the gameplay: campaign, special ops (the cooperative mode) and multiplayer. The game is a first-person shooter, like the other Call of Duty games.
