People compare it to the OST of 117 from Halo 4, but its got that sight difference in tune that sounds like the Lore of the first Halo Trilogy, if anything sounds like a heavier version of Halo 2’s scarab run at a slower pace and piano included:
Halo 2: Unrelease Track of Meropolis
Halo 4: Making of: Infinity Multiplayer (1-1:30)
I’m not really hearing that Halo 4 sounds from 117, more from Halo 1-3.
