* Most of the soundtrack is pretty awesome, but "[[http://www.youtube.com/watch?v=OI7uN_9wdPg Battlefield of Steel]]", a chilling mix of Techno and OminousLatinChanting, takes the cake.
** Doesn't hurt that this track tends to accompany a number of the game's [[CrowningMomentOfAwesome Crowning Moments of Awesome]].
* Also the ending theme [[http://www.youtube.com/watch?v=dGgZ0i9mbuc "Dawn Walker"]] by NANA, who has been pumping [[CrowningMusicOfAwesome rather awesome stuff]] for a lot other eroges including VisualNovel/KiraKira and VisualNovel/GreenGreen. This particular song really captures the heartwarming feel of the ending, [[EarnYourHappyEnding especially after all the hellish shit the cast goes through]].
* The opening, [[http://www.youtube.com/watch?v=yuBwjUYkDKw&hd=1 Dissonant chord]], which is also sung by Nana.
** And now, also done by [[http://www.youtube.com/watch?v=mycXBKzQjbk Angela!]]
