The Gun Game mode in Call of Duty: Modern Warfare 2 adds the classic Call of Duty mini-map to the game. Some fans have criticized developer Infinity Ward for not reverting to the classic Call of Duty mini-map in Modern Warfare 2.
For those unaware, Modern Warfare 2 doesn’t mark enemies as red dots on the map whenever they shoot, as it only displays them whenever a UAV is active. This means that players cannot figure out the exact position of their opponents when they shoot from a gun without a silencer, much to the disappointment of some Call of Duty users. Now, it looks like this classic mini-map does exist in Modern Warfare 2, but it seems to be limited to one game mode.
