Halo (Halo 3 level)

Halo is the ninth and final campaign mission of Halo 3.

Plot
After making it to the Installation near the Ark on a UNSC Frigate, Johnson, Master Chief and the Arbiter attempt to activate the ring. 343 Guilty Spark resists, killing Johnson and is destroyed by Master Chief and the Arbiter, who then activate the ring. What follows is an extended Warthog race back to the ship, in reference to The Maw. Cortana is uploaded to the frigate and guides it out towards the slipspace portal located above the Ark. Due to the incomplete nature of the Installation, the firing mechanism destroys both that Halo and the Ark, as well as launching the pulse that destroys sentient life and eradicating the Flood. Only the front half the ship makes it through the portal, with the Arbiter in tow; the other half is floating somewhere in deep space with Master Chief and Cortana. Cortana sends out a tracking beacon, while Master Chief puts himself in a cryogenic chamber, the same type he emerged from in the beginning of the first game. Back on Earth, in March of 2553, a monument is dedicated to the war and all those who perished in it. The Arbiter pledges his friendship with humanity before leaving the system with the remains of the Covenant fleet.

Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the "Return" achievement and 50 Gamerpoints.
