Evil Within is a fairly mediocre game. The soundtrack however is pretty good and I think it might be a good fit for some horror writing. It’s a bit upbeat, which isn’t always my cup of tea, but I can see it working for the right kind of story or chapter. It has some pounding, almost industrial sounding tracks, interespersed with some quieter passages with a bit more atmosphere. You could probably eliminate some of the more hardcore tracks for an easier listening experience.
Anyway, I’m not a music critic, take a listen and judge for yourself.
