Alliance

Alliance is the ninth campaign level of Halo 5: Guardians.

Glitches
If a player jumps off the edge of one of the cliffs and falls to their death, their corpse will go through the rocky sides of the cliff and disappear.

Easter Eggs

 * A singing Unggoy can be found on a ledge in the level. If spoken to, he will explain that he heard the song from a human prisoner.
 * A Sangheili and Unggoy called Dimkee Hotay can be found on a ledge admiring the scenery. If the player waits around them for a bit, the Grunt will begin to comment on different aspects about the Halo franchise rather humorously, including the home planet of the Brutes, the Master Chief's tendency to be unstoppable, and the honor code of the Elites. The Elite will in turn simply grunt back in reply.
 * There is a piece of rock in the cliffs of the level that resembled a human face.
 * An Intel audio log can be found in the level describing interspecies affection between Sangheili and humans. The log is of the Sangheili Vel 'Trokaik reciting a love poem about Sarah Palmer, before being humorously interrupted offscreen by a Grunt.
