It's very much what you'd expect it to be for a game like this, in a good way. Sweepingly epic with a grand orchestral arrangement to match, it's the kind of track that takes you to many places both thematically and emotionally, and is most definitely worthy of being the main theme of the game. 8.5/10.
While the game itself doesn't appeal to me this track certainly sounds like it could be in a 80's movie, and if the rest of the OST is as cool as this one then I can see myself putting the soundtrack as background noise. 8/10
9/10 I know 2 gets a lot of hate for the anime plot and the pivotal scene near the end where the protagonist SHOOTS HIMSELF to get the medic to get over her fear of blood, but tbh there was no other way to do that imo and the plot was fine if albiet a bit anime.
