For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
Chaos Warriors of the World (Warhammer & WH40K Chaos Tribute)
Created by Yours Truly
The song is Warriors of the World by Manowar, but this particular version is one which I reduced the speed on to alter its mood and the singer's voice so it was more Chaos-y.
If interested the actual song is here: Youtube.com
(Edit: Oh and btw... a thousand apologies for the subtitles in some parts... just try to ignore them. Source material without them was hard to come by... and I'm lazy. That doesn't help).
