While discussing the new addition to Call of Duty 4: Modern Warfare on the Call of Duty forums, some players were not happy about the fact that they could only use a keyboard to view the game's interface, and did not like being able to use a mouse to perform other functions. Unfortunately, as is common to all games that are developed for multiple platforms, the player is also unable to utilize a keyboard arrow key to switch between views. While playing on the Mac, as is the case with all previous Call of Duty games, players have the option to switch between the first-person perspective and a third-person view using a keyboard arrow keys combination.

In this game there are a variety of upgrades, abilities, weapons, medals, and achievements, and gamers are even allowed to customize their players with different skin colors. Like all other Call of Duty games before it, Modern Warfare features first-person view with an optional zoom feature.

The game can be purchased directly from developer Infinity Ward, or through various online retailers. Call of Duty 4: Modern Warfare is one of the most popular games on the market today and is available for both Windows and Mac operating systems.
