The Covenant control Earth. The Flood is unleashed. With the fate of the galaxy hanging in the balance, Master Chief is the only one that can save the human race. The entire epic story arc has led up to this moment. Master Chief, the last of his kind, is a warrior born for combat, bred for war… and humanity’s only hope.

After stowing away on a Forerunner spacecraft, Master Chief, a genetically altered, cybernetically enhanced Spartan supersoldier, must race back to Earth to stop the Covenant once and for all and save mankind. With his artificial intelligence companion Cortana in the grip of the Flood’s intelligent embodiment, Gravemind, Master Chief and his allies are vastly outnumbered. But the stakes are too high to do anything but face them head on.

In “Halo 3,” the third installment of this legendary epic, the war has come to a climax - the Flood continue to grow in numbers and strength, the armies of Earth are scattered and decimated, and the Covenant threaten to activate the Halo, effectively destroying all life in the galaxy. Master Chief’s mission: to stop the Covenant, destroy the impending Flood threat and ultimately save mankind

To celebrate the impending launch of the biggest entertainment event of the year, premiering “Halo 3” on the biggest screen imaginable - IMAX - seemed only fitting. Gamers in attendance will have the chance to play the recently finished game projected on the world's largest IMAX screens.
