Today, a new chapter in the legendary “Halo” saga opens up with the highly anticipated launch of “Halo 3: ODST.” After finishing the fight with Master Chief in “Halo 3,” players now have the opportunity to take a step back in time and experience the “Halo” universe from a whole new perspective.

Last night, thousands of retailers around the world opened their doors to usher in a flood of fans who sought to be the first to play the critically acclaimed title. Launch festivities were capped off with a “Halo” franchise celebration at the Experience Music Project | Science Fiction Museum and Hall of Fame in Seattle, where Bungie and 343 Industries luminaries were on hand to meet and greet fans and celebrate the launch together.

With “Halo 3: ODST,” developer Bungie takes the “Halo” franchise into all new territory. Players are put in the boots of an Orbital Drop Shock Trooper, some of the toughest and bravest soldiers of the UNSC. Players must search for clues to find out what happened to their squad when a drop into the city of New Mombasa goes wrong, and discover the secret behind the Covenant’s interest in the city.

In addition to a full-fledged campaign, “Halo 3: ODST” introduces Firefight, a new cooperative multiplayer mode where up to four players battle waves of unrelenting Covenant onslaughts. The game also introduces three new “Halo 3” competitive multiplayer maps and contains the complete, standalone “Halo 3” multiplayer experience on a second disc. “Halo 3: ODST” will also act as a key to entry into the “Halo: Reach” multiplayer beta at a later date.
