Spartans, ready your assault rifles and prepare to take the fight to new fronts! The Covenant crushed human defenses on Reach, but the fight for humanity’s survival still rages on in three brand new battlefields set on the doomed planet. With maps set on a giant orbital station high above the burning surface of the planet, hidden inside the forest of a military wilderness training facility, and wrapped in the remnants of a civilian mining site, the Defiant Map Pack brings awesome new environments for Firefight matches and all competitive multiplayer modes.
