Bungie has confirmed that central Halo series protagonist Master Chief will be in Halo: Reach. His appearance will be in the form of an unlockable voice, which can be assigned to your character in Firefight. Reach will also have a few other notable unlockable voices, including Buck from ODST, Sergeant Johnson and Cortana. We’re guessing the voices can be unlocked through Halo: Reach’s new Armoury system, where players can buy items to customise their characters. Reach is released on 14th September.
