Halo 4 continues the story of Halo 3, not Reach, which was a separate story line. This installment marks the first time Bungee will not be involved in the Halo triology, and instead is being replaced by 343 Industries, which is owned by Microsoft Studios.
Halo 4 will be released on November 6, 2012. It will again feature the main character John Master Chief 117 as he kicks Covenant ass along with a new unnamed enemy. Below is the Commissioning Experience trailer revealed during the Xbox press conference for E3 2012:
