Taking place shortly after the events of the novel Halo: First Strike, Halo 2 opens with the trial of Thel ‘Vadam, a Covenant Elite commander in charge of a fleet from the first game, aboard the Covenant’s mobile capital city of High Charity. The Elite is stripped of his rank, branded a heretic for failing to stop the humans from destroying Halo, and is tortured by Tartarus, the Chieftain of the Covenant Brutes. On Earth, the Master Chief and Sergeant Avery Johnson are commended for their actions at Halo. Lord Terrence Hood awards the soldiers alongside Commander Miranda Keyes, who accepts a medal on behalf of her deceased father, Captain Jacob Keyes.
A Covenant fleet appears outside Earth’s defensive perimeter and begins an invasion of the planet. While the UNSC repels most of the fleet, a single Covenant cruiser carrying an important member of the Covenant hierarchy, the High Prophet of Regret, assaults the city of New Mombasa, Kenya. The Master Chief assists in clearing the city of Covenant; with his fleet destroyed, Regret makes a hasty slipspace jump, and Keyes, Johnson, Cortana and the Master Chief follow aboard the UNSC ship In Amber Clad. The crew discover another Halo installation; realizing the danger the ring presents, Keyes sends the Master Chief to kill Regret while she and Johnson find Halo’s key to activation, the Index.
Meanwhile, the disgraced Covenant commander is presented before the Prophet Hierarchs, who acknowledge that though the destruction of Halo was his fault, he is no heretic. They offer him the honored position of Arbiter so that he can continue to fight for the Covenant. On his first mission to kill a heretic, the Arbiter discovers 343 Guilty Spark, who the Covenant calls an “oracle,” and brings him back to High Charity. Responding to Regret’s distress call, High Charity and the Covenant fleet arrive at the new Halo, Installation 05, just before the Master Chief kills Regret. Bombarded from space, the Chief falls into a lake and is rescued by a mysterious tentacled creature.
