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 he sings from a human prisoner.
 * A Sangheili and Unggoy 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.
 * Two of the Intel audio logs that can be found in the level hint at both interspecies and homosexual affection in Sangheili. One of the logs is of an Elite reciting a love poem about Sarah Palmer, before being humorously interrupted offscreen by a Grunt. The other is the confession of an Honor Guard, stating that Thel 'Vadam's mere presence arouses him.
