"Sources tell Kotaku that Call of Duty: Modern Warfare 3 will have as many as 20 multiplayer maps, though it's unclear if some will be cut before release or perhaps sold later as expansion packs. The game will also include a powerful mix of mission-based and survival Special Ops modes. While the mission-based levels will be designed like the ones made popular in Modern Warfare 2, we're told, the survival maps will have players fighting until they're overcome by increasingly difficult waves of enemies.
