Developed exclusively for Xbox 360 by acclaimed developer Bungie, Halo 3: ODST is a new, stand-alone expansion to the Halo saga that lets players experience the events leading up to the epic story told in Halo 3 through the eyes of an entirely new character the ODST (Orbital Drop Shock Trooper), as they search for clues leading to the whereabouts of their scattered squad and the motivations behind the Covenant's invasion of New Mombasa. The game adds a new dimension to an all-encompassing universe that gamers around the world have known and loved since the release of the first Halo game in late 2001. Features * Stand-alone expansion to Halo 3 that doesn't require ownership of the previous game to play. * ODSTs: Follow the story of the legendary ODSTs or Orbital Drop Shock Troopers as they drop into the ruined city of New Mombasa, looking for clues behind the Covenant's catastrophic attack on the city. * A new hero: Prepare to drop. Known for their courage, valor and at times, insanity, Orbital Drop Shock Troopers are among the fiercest UNSC soldiers, priding themselves on being the first unit deployed into hostile situations. While not as large or supernaturally gifted as their Spartan comrades, these Hell Jumpers more than compensate with their ferocious attitudes and unwavering nerve. * New campaign, hero and tactics from the Halo universe as players take on the role of a rookie in the Orbital Drop Shock Troopers sent into New Mombasa. * 4-player co-op "Firefight" mode offers a whole new way to play Halo with friends both via system link and over Xbox LIVE. * Along with all the existing Halo 3 maps, ODST contains three new multiplayer Halo 3 maps: Heretic, Longshore, and Citadel. * Halo 3: ODST contains 1,750 new Xbox LIVE achievement points, as well as new weapons, technology and an invite to join the Halo: Reach beta in 2010.
