Sound of something from somewhere as best i can remember. Seems like it is the sound of a claymore or the like, in some game; by the time you hear it you know you are going to die. I messed with it at the end but you can cut that off if you want. No explosion at the end.
Created with granular synthesis. Something related to a spaceship, engine room, another drone sound; could be a distant low end for a pad, as it is tonal (a note). Will loop if you crossfade between start and end. Enjoy. Https://soundcloud. Com/vospi.
