Call of Duty: Black Ops for the DS is a companion product to the 360/PS3/PC/Wii versions that put gamers in the boots of CIA-backed operatives that are dropped into the shadowy world of deniable operations with an expansive arsenal of weapons at their disposal. Its storyline and missions are meant to provide a different perspective and fill in the overall story. In the end, Call of Duty: Black Ops for the DS provides a great new Call of Duty experience for players that have one of the other versions as well as players who only decide to pick up the DS version.

The game was built on same great technology as our previous Call of Duty games, but, as with each game, we dig in deep to optimize, revise, and add more capabilities to our tech to push the system and provide a better game for players. For Black Ops, we spent a good deal of time during development communicating with the fans of the previous games through various forums, learning what they liked, disliked, and truly wished for in a follow-up . We also took on the same players in a series of online matches, directly learning how they played the game. We used that collected feedback to help build the features for Black Ops.

The User Interface has evolved with each Call of Duty game we've released, and this time we started with the goal to create a system that was faster and more intuitive when it came to accessing weapons and basic actions. For example, when picking up a dropped weapon in Black Ops, the player can simply tap the icon to swap out for the new weapon like past games – or drag and drop the weapon onto an inactive button, adding it to their inventory without replacing the weapon they're currently using.

Major improvements and additions were made to multiplayer as well, but we can't get into too much detail just yet. One thing we can confirm is (by popular request) the addition of a Perks system modeled after the console games. We're proud to say that the team is raising the bar for the first-person, multiplayer experience on DS with Black Ops.
