"This new title is a more straightforward account of the experience that awaits and the role you will assume as you explore the streets of New Mombasa," explained Bungie.

The standalone Halo 3 expansion pack, a stealth-involving prequel to the Xbox 360 shooter that details the invasion of Earth from the perspective of an Orbital Drop Shock Trooper (ODST), was announced earlier this year.

The new name is "literally pronounced 'Oh-Dee-Ess-Tee' and not 'ohdst,'", Bungie noted. The game is said to pack 3-5 hours of single-player gameplay and will hit retailers next fall, with Bungie recently stating it is not viewed as a $60 title.
