Headshots Only

Headshots only is a mode that appears in Call of Duty 4, Call of Duty: World at War, Call of Duty: Modern Warfare 2, and Call of Duty: Black Ops as an option for private matches. The option makes it impossible to do damage to another player unless a Headshot is aquired. This makes the game much more difficult to play, as most shots will do nothing, and players must aim carefully.
