Halo 4 is the first new installment in what will become the second Halo trilogy by 343 Industries. The studio was founded in 2007 to oversee everything Halo, but beside some work on map packs and the HD overhaul on the original Combat Evolved, Halo 4 is the first completely new title 343i has worked on. The studio consists of over 250 people, including some ex Bungie and ex Ensemble Studios employees. With a new beginning the development team has gone all out on the personal story of Master Chief and specifically his relationship to Cortana. Check out this 10 minute mini documentary about the story, mocap and voice acting (after the click). The game will be out november 6th.
