ANOTHER MUSIC QUESTION

Alright, so this is like my last question, but a different song.

So what instruments are used in the song Carrion? In case you don't know what Carrion is, it's a song by Kevin Sherwood and is used in Call Of Duty Black Ops Two Zombies on the map TranZit. I kinda just want to know what instruments are used and how I could do it on something like a piano or something. Sorry if this isn't the right topic for art, if it isn't then I will ask some Art-Related Questions. I would provide an MP3/MP4 of the audio, but it wouldn't let me. Also thank you for your time :D
