Twins Zack and Cody Martin check out of their Tipton Hotel home to embark on an action-packed adventure to reveal a covert spy organization. To piece together the clues, players will control both Zack and Cody in a series of 3D platform stages within the following three environments: St. Mark Hotel, an underground passage, and a traveling carnival. Puzzles and enemies can be solved or defeated using a variety of gadgets, from Cody's modified vacuum cleaner to Zack's spring shoes. At the end of each area, players must complete one of three mini-games: "Balance," "Whack-a-Ghost," and "Air Hockey," with the latter two available for play against a friend. Based on the Disney Channel's sitcom, The Suite Life of Zack & Cody: Circle of Spies is the second DS title starring real-life brothers Dylan and Cole Sprouse.
