This reminds me of Dumah's battle theme from Soul Reaver.
All in all, very good drums, tribal, angst, and fear with the song. It's great for a game with someone like that in it.
I'd give it 3.75
It's not 3.5 quality, but I don't think it gets the 4.0 either. Perhaps it's because you lost yourself with the song when you realized it wouldn't go past this and it was left hanging. There's something lacking. It's still great ambience though. Not a lot of songs like this around. Kudos.
