Which Nintendo DS game is the companion to Modern Warfare 2?

Which Nintendo DS game is the companion to Modern Warfare 2? Modern Warfare: Mobilized is the answer.

Released by Activision on November 10, 2009, Call of Duty: Modern Warfare: Mobilized was developed specifically for Nintendo DS by n-Space. It takes place in the same general setting as Modern Warfare 2 and was launched alongside the console and PC versions.

Mobilized is not a direct handheld port of Modern Warfare 2, nor does it retell the same campaign. Its storyline is a companion narrative, following separate SAS and U.S. Marine characters as they attempt to stop a nuclear plot. That distinction is the key reason it is paired with Modern Warfare 2 rather than treated as the DS version of the game.

The DS game also adapted series features to Nintendo’s hardware, including vehicular missions, UAV control, an AC-130 mission, hacking mini-games and six-player online multiplayer. Roads to Victory was instead a PlayStation Portable game, while Modern Warfare 3: Defiance was a later Nintendo DS companion to Modern Warfare 3.
