Watch the Halo 3: ODST Live Action Trailer – “We Are ODST”

From IGN —

Halo 3: ODST’s tale focuses on 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.

The new campaign chapter predates the events that unfold in “Halo 3” and gives players a new perspective through the eyes of a new hero in the “Halo” universe. New multiplayer maps ensure that the award-winning Xbox LIVE experience of “Halo 3” continues to thrive.
