Paramount revealed the first Halo live series trailer during The Game Awards 2021. It's big on setpiece moments but short on details. There's a multitude of characters who will seemingly play significant roles in the series, but little context on who they are and how they relate to Chief. However, it does seem the Halo live series will focus more on the Master Chief's background and the pressures and expectations put on him as a Spartan, a fitting emphasis given Halo Infinite's narrative direction.
The Halo live series will air in 2022. Check out the trailer below:
