**UPDATE 08-24-2016** Added 11 new random sounds. This replaces all the music for levels with a creepy industrial background noise. Interspersed with that, you will hear random screams, pain, voices, and monster sounds. The noises occur at random and at varying levels of volume. If you are looking for a creepy ass atmosphere when you play, this is it. This is standalone and will work with any other mod, although it will override any other music mods. I will be including this with the next version of Ultimate Doomvisor that will be out soon. Stay creepy and stay brutal!
