During Microsoft's Pre-E3 press briefing Bungie's Joe Staten took to the stage and dropped gamers into the first gameplay footage of Halo 3: ODST. In the game players will take on the role of a rookie Orbital Drop Shock Trooper weeks before the events in Halo 3. As part of the single-player campaign expansion, Halo 3: ODST features a greater mystery, as 'The Rookie' attempts to uncover the truth about his fellow hell jumpers. The game features new silenced weapons, a visor -- enabling a 'low-light vision mode' used to point out crucial information -- and a handgun original (Halo) gangsters are sure to 'love,' said Staten. Prepare to drop ($59.99 or more) later this year.
