Microsoft chose the Tokyo Game Show to finally lift the veil on Bungie's next Halo project. The game is officially called Halo 3: Recon and it purports to offer all-new campaign content. However, it won't star Master Chief. This side story takes place prior to the events of Halo 3 and details what happens leading up to the Chief's return to New Mombasa. This time, you'll play as a member of the special forces known as the Orbital Drop Shock Troopers.
