Question about the soundtrack (description of scene is kinda spoiler for Chapter 3)
 

What's the song that's playing in the background while Oscar has the epic knife battle against the Raptor in Chapter 3?

I'd like to know, too, because it sounds familiar... or maybe I'm just hearing things.

It's an original song composed and performed by Jared Emerson-Johnson for the game. Lyrics written by Andrew Langley.

That's the inside scoop.

It's not on the digital soundtrack from the deluxe edition, is it? I listened to the intros of all songs and didn't find it.

No, the song is not part of the deluxe edition's soundtrack release. I'm curious as to why, because it is in amusing bit of music in the game, and doesn't use Williams themes. I guess we can safely call the included soundtrack a "sampler", lol. To be fair, this is how most soundtrack releases are, even for film. The always leave off good or interesting tracks, sometimes even the best ones. So I guess I'm used to this. ;)

But hey, still happy with what we have. It does include that new theme that is very pretty, and at least it is in 320k quality.
