About Call of Duty: Modern Warfare 4
Call of Duty: Modern Warfare 4 (MW4) is a military first-person shooter developed by Infinity Ward and published by Activision. The campaign follows Private Park and a South Korean squad fighting through a conflict on the Korean Peninsula, while Captain Price carries out a covert mission beyond the front lines. From trench warfare to urban assaults, the story takes players through intense battles across multiple locations.
The main MW4 game modes offer three distinct ways to play: a story-driven Campaign, competitive Multiplayer, and the DMZ extraction experience. Multiplayer features 12 new 6v6 maps alongside larger battlefields with infantry and vehicles. In DMZ, you can deploy solo or with a squad, complete objectives, collect equipment, and decide whether to push for more loot or head for extraction.
When comparing MW4 vs MW3, the map lineup and main modes are two clear differences. MW3 launched with remastered classic maps and an open-world Zombies mode, while MW4 introduces new launch maps and brings DMZ into its core lineup alongside Campaign and Multiplayer. For returning players, that means new battlegrounds to learn and a different set of challenges beyond traditional competitive matches.
