Arrival is the first level in Halo 3. It does not contain actual gameplay, consisting instead of a look inversion test on lower difficulties, and the game's opening cutscenes.
Plot
The Master Chief crashes in an African jungle near Mount Kilimanjaro and is eventually recovered by Thel 'Vadam (the Arbiter), Sergeant Major Avery Johnson, and several Marines.
In Heroic and Legendary, the only point in doing this level is because you cannot get the Campaign Complete for the Heroic and Legendary Achievements without doing so.
