With ninja-like stealth, Rockstar Games quietly released Grand Theft Auto: Chinatown Wars in the U.S. [App Store, $9.99]. The game puts you in control of Huang Lee, the son of a Triad gang boss. After your father was murdered and driven off the side of a pier, it's your job to get back the family heirloom— an ancient sword— and deliver it to your uncle to ensure that control over the Triad gang stays within the family.
