Worldquake
From Halopedia, the Halo wiki
Worldquake is the twenty-fourth track on Volume 1 of the Halo 5: Guardians Original Soundtrack. It is used during the Promethean and Warden Eternal battle in Battle of Sunaion, in Blue Team while defending the ONI Prowler, when climbing the space elevator in Evacuation, when witnessing Covenant dropships attacking the Elder Council Chamber in Swords of Sanghelios, in the triple Warden fight in The Breaking, and twice in Guardians; the first time which is when Fireteam Osiris and 031 Exuberant Witness encounter Covenant and Promethean forces slaughtering each other, and the second and last time which is when Osiris and Exuberant encounter a wave of Promethean Knights while attempting to lower the relay.
