Deeds of darkness

Within walls of steel
Dark deeds are done
Screaming human subjects
The experiments have begun

Flay the flesh from the bone
Weave the skin with metallic chrome
Tear out the muscles and make them anew
Strip out his beating heart and replace it too

Blood covers the walls
The screaming never subsides
And the metallic scraping
Leads to even more of the crimson tide

Damned creatures are created
Blood dripping from their eyes
It's difficult to tell what is real
And what has been synthesized

Oh yeah
