Call of Duty: Black Ops for Nintendo DS will include a six-player multiplayer component (like last year's
Modern Warfare Mobilized). The franchise is known for its perk system, and it will return for the handheld companion game. Details are sparse at the moment, but we expect more to be disclosed as the game approaches its street date.
In addition to the online competitive multiplayer, the game will include two player co-op, Arcade mode, and Challenge mode. The first of those is self-explanatory, but the latter two allow the player to revisit completed missions and unlock achievements.
