I am fairly sure the music used for the part, where you obtain the Captain's firearm, is ripped right from a game for Nintendo DS called "Dead N Furious" also known as "Touch the dead"
I pulled all the music/sound effects from royalty free CD’s I’ve owned for 20 years. Maybe that game used the same cd’s as a source? In any case, 100% legit on my side. FYI.
