Misc Computer Games - Call Of Duty Black Ops - Damned Intro Chords & Tabs

This is the song from Call Of Duty: Black Ops, Zombie mode. You know, when you're in the 
mode lobby, you hear this song. I figured since there's no other tab on the internet, 
I'd do this song. I did this all by ear, so sorry for any mistakes. Only the intro so far.

And that's all I have for now. It can be played on piano this way too, but obviously, 
play the note instead of the frets, 'cause pianos don't have frets. Any problems, message
