Much more than an expansion, Halo 3: ODST allows players to explore dangerous new ground, search the dark, abandoned streets of New Mombasa for clues, and fight back against the Covenant invasion from multiple perspectives. Dropping in as "the rookie," a new member of an elite squad of Orbital Drop Shock Troopers sent into New Mombasa on a classified recon mission, you'll be armed with specialized weaponry and upgraded technology, including silenced weapons and a VISR enhanced vision mode.
Separated from your squad, you'll have to scour the city for clues in order to learn what happened to Buck, Dare, Dutch, Mickey, and Romeo. As you collect new clues, you’ll experience the story from their perspectives, fighting through the occupied city hours earlie

Drop feet first into a new way to play Halo with the cooperative campaign mode, Firefight. Form a squad of your friends over System Link or Xbox LIVE and put your skills to the ultimate test against the invading Covenant war machine for glory, high scores, and achievements. Do battle in multiple environments, on foot or in vehicles, and against increasingly difficult waves of Covenant attackers while Halo 3's skull modifiers progressively activate to up the ante.
After the Firefight, relive and review every last kill you earned and see how your high scores and stats stack up against your friends' and the community overall using Bungie.net's persistent online stats and Firefight leaderboards.

Three all-new maps make their debut for Halo 3's traditional, chart-topping multiplayer. Heretic, Longshore, and Citadel drop in alongside the original Halo 3 Multiplayer Maps, all packed in and playable from one standalone disc. Twenty-four maps in all, including the Heroic, Legendary, Cold Storage, and Mythic Map Packs, provide a peerless multiplayer experience, near limitless content creation and customization via the Forge and Sandbox, and a slew of new multiplayer achievements for Halo 3.
this one is awesome
