There are three parts to the special ops mode: the Mission, Survival and Chaos modes. The Mission mode is a game mode that comes back from the special ops mode of "Call of Duty: Modern Warfare 2". In the Mission mode, players do lots of different missions and get stars for their work. The Survival mode is a new game mode. In the Survival mode, waves after waves of enemies attack the player/s. There is no way to complete Survival mode because the waves keep coming. There are thirty seconds between each wave of enemies. This is so the player has time to buy weapons, explosives and Pointstreaks. The Chaos mode is another new mode. 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. Weapons are scattered around the map, and perks and care packages assist the players.
