This is my first tab and i think it sounds about right.
This riff goes throughout the entire song.
[ Tab from: http://www.guitaretab.com/f/fort-minor/83612.html ]
piano:
e-----14-13-14-15-14-13-14------14-13-14-15-17-15-14-*
B--12------------------------12----------------------*
G----------------------------------------------------*
D----------------------------------------------------*
A----------------------------------------------------*
E----------------------------------------------------*
And thats it. it took me about 10 secconds to figure it out myself so this should be no problem.
