Call of Duty: Black OpsCall of Duty: Black Ops

The Nintendo DS version of Call of Duty: Black Ops has many new features like the Perks system for the six player online multiplayer. The player can tap an icon to switch the current weapon for a new one, like past DS games, or drag the weapon into an inactive button to add to their inventory without replacing the weapon they are using currently. An auto lock-on feature is available to use in the Recruit and Regular difficulties.
