$20 off select Halo 3 games for Xbox 360, plus free shipping at BestBuy.com. The Covenant rules the Earth — the Flood has been unleashed — and the fate of life everywhere hangs in the balance. There is only one person capable of saving the human race: Master Chief. This genetically engineered super soldier is the last chance for humanity's survival. Everything he has gone through has led him to this monumental moment. Stowed away on a Forerunner ship, he rushes back to Earth to defeat the Covenant once and for all. Hopelessly outnumbered, and with his Artificial Intelligence companion Cortana ensnared by Gravemind, things look bleak. But when you are bred for battle like Master Chief, you fight past the breaking point and bow to no one. It's all been building to this — a desperate, final war that leads to a soul-shattering climax of epic proportions. Help this incredible hero stop the Covenant, destroy the Flood and save the lives of every person on the planet.
