You're a Marine, one of the badess mother ****er in the UAC. But nothing ever happens here... You were made to rip, tear and kill. As you're asleep from the boredom of this place, you dream of taking the skin off of Demon's skulls and be the killer you were always meant to be. You wake up to the sounds of your fellow brothers and sisters in arms screaming. You hear the foot steps of pure evil a foot, you grin and make your way to the door with pistol in hand. Time to rattle some heads. Time to go back to episode 1 because we have Megadeth's first album Killing Is My Business... and Business Is Good!, I give you a full MIDI version of the album titled Slaying is My Business.... This mod takes all the tracks off the album (With a bonus track) and replaces the Doom tracks off of Episode 1. Hope you enjoy, now time to get to business.
