<poem> Spilled guts and glory Urban Legend, I am that story It's the killer killers captain MP Anti-Personnel Control And I'm out of your control I just do what I know Do it Better than anyone I know Let my body count speak for me I see where puzzle pieces fit And got the ear of royalty From a royal bloodline Strong as identity Underground survivor Know how to stay alive Murder Urban Legend Knife to the throat with no hesitation Quick cuts and keep moving Draw no attention while I work up front in the background Never one to back down Move up and keep moving Need god-like power to be Better than me Better to be a better me I'd kill for that Elite and loyal squad Willing to back any play I make Spill a whole lot of blood if that's what it takes to Saves lives, take lives Simply prioritize Got goals to achieve now open your eyes, see past the lies Let's play it like a blood sport Fight for your life or die It's your choice Sometimes it's capture or kill Squash the dissenting elements Torture the enemy, just for the hell of it Tell me to care, but I just can't My patience for this has gone dark After patience let the fun start The knives and guns come out The option for living is getting revoked My squad will leave you broken But may be me that slits your throat like a sheep or a goat Remorseless The course of action is merely a by-product of my focus The closer I get The more I'm willing to go beast-mode Spilled guts and glory Gory as it gets, I am that story Can god-like power make me a better me? I just wanna see
