In Halo: Reach, players experience the fateful moments that forged the Halo legend. It's the story of Noble Team, a squad of heroic Spartan soldiers, and their final stand on planet Reach, humanity's last line of defense between the terrifying Covenant and Earth. This darker story is echoed by grittier visuals amid a backdrop of massive, awe-inspiring environments. Characters, enemies and environments are rendered in amazing detail by an all-new engine designed to deliver epic-scale encounters against the cunning and ruthless Covenant.

Once the campaign is over, the battle continues online with an unparalleled multiplayer experience that expands on the award-winning suite of features that helped define the Xbox LIVE experience.
