Halo - The Master Chief Collection [Halo 2 Anniversary] - Part 6 - Walkthrough HD (No Commentary)

Halo 2 opens with the trial of a Covenant Elite commander aboard the Covenant's capital city-ship of High Charity. For his failure to stop Halo's destruction, the Elite is stripped of his rank, branded a heretic, and tortured by Tartarus, the Chieftain of the Covenant Brutes. Spared execution, the Covenant leadership—the High Prophets Truth, Regret, and Mercy—give the Elite the chance to become an Arbiter, a rank given to Elites in times of great crisis or turmoil. As the Arbiter, the Elite quells a rebellion and recovers 343 Guilty Spark. On Earth, Fleet Admiral Hood commends the Master Chief and Sergeant Avery Johnson for their actions at the first Halo, with Commander Miranda Keyes accepting a medal on behalf of her deceased father, Captain Jacob Keyes. A Covenant fleet suddenly appears near Earth. In the ensuing battle, a single ship carrying the Prophet of Regret slips through Earth's defenses and besieges the African city of New Mombasa. Master Chief assists in repelling the invasion. 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 discovers another Halo installation; realizing the danger the ring presents, Keyes sends Master Chief to kill Regret while she and Johnson search for the Index, Halo's activation key. Responding to Regret's distress call, High Charity and the Covenant fleet arrive at the Halo. After Master Chief kills Regret, the Covenant bombard his location; he falls into a lake, where he is dragged away by tentacles. Regret's death triggers discord among the races of the Covenant, as the Prophets give the Brutes the Elites' traditional role as their honor guard. The Arbiter subdues Johnson and Keyes and retrieves the Index. Tartarus appears and reveals that the Prophets have ordered the annihilation of the Elites, and sends the Arbiter falling down a deep chasm. The Arbiter meets the Master Chief in the bowels of the Halo, brought together by a Flood creature called the Gravemind. The Gravemind reveals to the Arbiter that the Great Journey is a lie, and sends the two soldiers to different places to stop Halo's activation. The Master Chief is teleported to High Charity as the Covenant falls into civil war. The Flood-infested In Amber Clad crashes into the city, and Cortana realizes that the Gravemind used them as a distraction. As the parasite overruns the city, the Prophet of Mercy is consumed. As for Tartarus, the Prophet of Truth consigns him to Halo with Keyes, Johnson, and Guilty Spark to activate the ring. Master Chief follows Truth aboard a Forerunner ship leaving the city; Cortana remains behind to destroy High Charity and Halo if Tartarus succeeds in activating the ring. On the surface of Halo, the Arbiter joins forces with Johnson and confronts Tartarus in Halo's control room. When the Arbiter tries to convince Tartarus that the Prophets have betrayed them, Tartarus instead activates the ring, and a battle ensues. The Arbiter and Johnson kill Tartarus while Keyes removes the Index; the unexpected deactivation sets Halo and all the other rings on standby for remote activation from a place 343 Guilty Spark calls "the Ark." Meanwhile, Truth's ship arrives at Earth, and Master Chief informs Admiral Hood that he is "finishing this fight." In a post-credits scene, Gravemind assumes control of High Charity. Cortana agrees to answer the Flood intelligence's questions.
