Halo: Spartan Assault

Enlist as a Spartan soldier and sharpen your tactical skills in battle. Set between the events of "Halo 3" and "Halo 4," Halo: Spartan Assault, developed by 343 Industries in conjunction with Vanguard Games, is a new chapter within the Halo universe. Spanning over 30 missions in vibrant, dangerous worlds, dive deeper into the backstory of Human-Covenant wars, the origins of the Spartan Ops program, and unravel a chilling mystery in Operation Hydra. Play through the eyes of either Commander Sarah Palmer or Spartan Davis stationed aboard the UNSC Infinity as they fight never-before-seen battles against Covenant forces. You can also join with a fellow Spartan on Xbox Live, in battle against the Flood.
