Alright so here is another version of the Mask Walk from the level "Rebirth" in Call of 
Duty Black Ops. I think this one is a bit more accurate but may still contain certain 
flaws. If you have any suggestions, e-mail me at CFRRulez@yahoo.com

Here both guitars play at the same time:

e------------------------------------|
B------------------------------------|
G------------------------------------|
D-2-2--2--3-3--2-----5-5--4--4-4--3--|

And together again:

Guitar I
(0:59-1:04)
e------------------------------------|
B------------------------------------|
G------------------------------------|
D-2-2--2--3-3--2-----5-5--4--4-4--3--|
A-2-2--2--3-3--2-----5-5--4--4-4--3--|

D-------------------------       D-0-0---0---0---0---0-----|
A-------------------------       A-------------------------|
D-------------------------       D-------------------------|

Then Guitar II by itself:

e-----5---5---6---5---5/8-       e-------------------------|
B-3-3---3---3---3---3-----       B-------------------------|

A-2-2--2--3-3--2-----5-5--4--4-4--3--|
D-2-2--2--3-3--2-----5-5--4--4-4--3--|

Guitar I
(1:14-1:19)
e------------------------------------|
B------------------------------------|
G------------------------------------|
D-2-2--2--3-3--2-----5-5--4--4-4--3--|
A-2-2--2--3-3--2-----5-5--4--4-4--3--|
D-2-2--2--3-3--2-----5-5--4--4-4--3--|

After this part they play together again. This is basically the order they play in. 
There are videos on Youtube but the song length varies in every video.

Also here is another way to play Guitar I:

e----------------------------------------------|
B----------------------------------------------|
G-9-9--9---10-10--9-----12-12--11---11-11--10--|
D-9-9--9---10-10--9-----12-12--11---11-11--10--|
A-7-7--7---8--8---7-----10-10--9----9--9---8---|
D----------------------------------------------|
