This is the theme song from Metal Gear Solid 2's intro.  In Metal Gear Solid 3 it is played on a guitar, so I tabbed it out for everyone who wants to play it.

G----------------------------7-5--------5-7-10-9-10-12-10-----------9-10-9------------
D-7-5-3---5-7-0-7-5~---3-5-7-----7-3-5~-------------------12~-10-12--------12-10-12~~~
A-------------------------------------------------------------------------------------
E-------------------------------------------------------------------------------------

Usually after I play it this was I jump around the fret board playing the same pattern in different spots.  I like to end it this way.
