The year is 2552. Covenant forces control the city of New Mombasa. They are searching for something beneath its darkened streets. You are an Orbital Drop Shock Trooper. Your orders: stay alive, meet up with your scattered squad, and escape the embattled city.
Fan favourite and Halo series stalwart Sergeant Avery Junior Johnson is a tough-as-nails career Marine who has been in more life or death battles than you've had hot meals. He's survived more infectious Flood outbreaks, greased more Covenant bad guys, and earned more medals than any other twenty soldiers. And now you get to walk a mile in his shoes!
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 specialised weaponry and upgraded technology, including silenced weapons and a VISR enhanced vision mode.
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.
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.
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.
Run and gun: While not as large or supernaturally gifted as their Spartan comrades, these Hell Jumpers more than compensate with their ferocious attitudes and unwavering nerve.
Multiplayer: All the traditional features of Halo 3 multiplayer will be included in the new game, including full-featured integration with the Forge map editor.
