Microsoft has released a trailer for this week's Halo 4 Spartan Ops DLC.
Spartan Ops episode 4 launches today alongside a multiplayer playlist update. Here's the official description of the latest DLC:
"An unknown intelligence contacts Doctor Halsey, Thorne tries to understand the history of the Spartan Program, and the Sangheili terrorist known as 'The Didact's Hand' appears on Requiem... but what is he searching for? Spartans, prepare for things to get rough on Requiem."
Each week Microsoft is releasing five 10-15 minute long Spartan Ops missions as DLC, which are included in the retail price of the game.
Set around six months after the events of the campaign they essentially form a sequel to the main game focusing on two Spartan squads, Crimson and Majestic, rather than furthering Master Chief's storyline.
Season one of the Spartan Ops DLC will consist of ten episodes and 50 missions.
Release dates for Halo 4's War Games map packs have reportedly been revealed by an advert spotted on the German Xbox 360 dashboard.
