Uncharted is one of my favorite game series, and the first one is pretty entertaining (and the following sequels are even better). The soundtrack by Greg Edmonson consists of a nice orchestral composition, with "Nate's Theme" being one of my favorites: just a grand opening piece with lots of horns and sweeping violins, setting the tone for a grand adventure.

The rest of the soundtrack is great too, although more as a backdrop for the action scenes and not so much as a 'standalone' listening experience..in a way, this is like listening to the soundtrack of a movie.

You can buy the soundtrack on Apple Music. It's also on Youtube.
