This is the complete soundtrack of Assassin's Creed Revelations, all 3 CD's worth with a total of 80 tracks from YouTube, uploaded and compiled by by Gears2Halo.
All music belongs to Ubisoft and it's respective creators, watch in HD for best effect.
The soundtrack is just great, and big.
I might be posting the other OST's on the Assassin's Guild group, keep an eye out if you want...
