Halo 3: ODST (Orbital Drop Shock Troopers, released September 22, 2009) is a first-person shooter video game developed by Bungie and published by Microsoft Game Studios for the Xbox 360. Players can select a survival-themed multiplayer mode called Firefight, or select campaign mode to explore the ruined city of New Mombasa during an alien invasion in search of their missing teammates. Bungie initially conceived ODST as a small side-project slated between Halo 3 and Halo: Reach. Story director Joseph Staten penned a detective story with film noir designs, settings, and characters, and composer Martin O'Donnell created a jazz-influenced sound. The game grew in scope during development, and upon release, it became the top-selling Xbox 360 game worldwide. The title received generally positive reviews from critics for its atmosphere, music, and story approach. It was the top-selling title in the United States in its first month, even though reviewers were divided on whether the relatively short campaign and extras were enough to justify the game's $60 price tag. It sold more than 3 million copies worldwide, and Time and Wired declared the game one of the year's best. (Full article...)
