Yesterday at Microsoft’s pre-E3 press conference Bungie’s Joe Staten took the stage to show off some actual gameplay footage of Halo 3: ODST, which is scheduled to drop later this year. The single-player expansion campaign will put you in the role as “The Rookie”, a rookie Orbital Drop Shock Trooper, a few weeks before the events of Halo 3. Some features in the game include new silenced weapons, a new visor (which enables a “low-light vision mode”) and a handgun similar the pistol from the first Halo game.

Along with an expanded single-player campaign, ODST will also feature a four-player co-op mode called Firefight mode that will have players take on waves of attacking Covenant (think Horde mode from Gears 2). Check out the video and give us your thoughts.
