We know there are a lot. And we know they sound awesome. This thread is not about leaked content. It is about the titles which already give clues about the story and about the situation the soundtracks stand for.
The titles of the OSTs are
-Arrival
-117
-Belly Of The Beast
-Awakening
-Faithless
-Green And Blue
-Haven
-Legacy
-Nemesis
-Immaterial
-Solace
-To Galaxy
-Revival
-Requiem
-Ascendancy
-Awakening
We can be sure that this is also the order in which they will be heard during the game. So what do they tell us?
ARRIVAL is definitely Chief and Cortana being ecnountered by the Covenant fleet above Requiem’s outer shell.
117 refers to the Master Chief. He will be awakened and back to work, there is no doubt.
BELLY OF THE BEAST can’t be anything else than Requiem’s interior. The Forward Unto Dawn will be pulled inside Requiem and both Cortana and Master Chief crash-land on the planet.
AWAKENING is strange. I would put it at the beginning when the Master Chief leaves the Cryo Pod. But it seems to be about something happening later. Here you can hear the sample. It is also possible that something on Requiem awakens after the intrusion of Master Chief and the Covenant.
FAITHLESS refers most probably to two scenes. One being Cortana who has lived longer than she was supposed to do. She is already over the deterioration rate of an AI. Chief wants to find Doctor Halsey on Earth. He thinks that Halsey could fix Cortana’s problem. But obviously, there is no way out of Requiem, no way back to Earth is in sight yet. That probably leaves Cortana faithless.
GREEN AND BLUE is easy. I first assumed it referred to the Master Chief and Forerunners (because of the color of their armor). But it’s rather a sooundtrack for Master Chief (green armor) and Cortana’s (blue body) relation.
HAVEN – I assume it will play during the Infinity Mission. Or it refers to the Multiplayer Map.
LEGACY is the final moment when Master Chief will reclaim what the Forerunners had left for humanity.
NEMESIS is the introduction of the main enemies: the Prometheans, these Forerunner’-whatever-they-are-and-no-they-are-not-robots’things. It’s possible that it will also be about the Cryptum and what is sleeping inside.
IMMATERIAL reminds me of those Gravemind moments from Halo 3. Maybe it’s some sort of Forerunner chamber where all the personalities of the Forerunners are gathered. It’s in and about the 7th level “COMPOSER”, so-to-say.
SOLACE is not about the Halo Reach mission The Long Night of Solace. It could be about
Master Chief’s and Cortana’s relation again. We don’t know yet how bad Cortana’s rampancy has become nor do we know if she will survive Requiem. She could be saved by the Composer. It is a bit strange but if Cortana was made blood and flesh, it would explain why she can physically attack the Didact (as stated in the script).
TO GALAXY will be at the end. We heard the sample. It sounds as if the Nemesis will start off to the far reaches of the Galaxy and Master Chief and the UNSC forces are trying to stop him.
REVIVAL is one of the greatest soundtracks. It will be the awakening of what hides inside the Cryptum. You might wonder what makes me think that. Well, we know the Didact will be in Halo 4. And the Didact will most probably be resting in a Cryptum (how else could he have survived 100k years?). And the book Halo Cryptum states that Chakas and Riser chant. That chant helped open the Cryptum of the Didact. So my conclusion is that the chant of the soundtrack Revival is the same chant which opens the Cryptum/s.
ASCENDANCY is the rising Evil. The Ancient Evil ascends, trying to leave Requiem behind. Maybe it will be a single task force or an entire fleet (of Forerunners?) I assume it will play during the final mission “MIDNIGHT”.
I assume the second AWAKENING will be the revival of all Forerunners in the galaxy. Or the rest of the Ancient Evil’s force in case the evil is not the Forerunners. There might be more “members” of the Ancient Evil on other Shield Worlds in the galaxy.
Absolutely!!! I really can’t wait for the campaign! I will have to try and avoid spoilers until release! Multiplayer content is fine for me! And the music of course!
