Does anyone know what this is ?

Hi there. The music in this was just a composed orchestra etc, for the trailer itself. The beginning was the old Ubisoft logo sound. I suggest if you want it, get an add on for firefox which while download the video and convert it to Mp3 for you. If anyone else knows they will reply here.
