Sounds like something that could be in Madness Combat :D
But ending is a bit abrupt D:

Pretty awesome.

Honestly, I was going to click back to the audio portal when I first heard the intro. It's not a bad intro, I just assumed I knew where the song was going. But my computer lagged and I heard the change at 00:16, after which I had to return and give this my full attention.

You know what you're doing. I don't usually listen to dubstep unless it's heavy, but this was just so well-crafted.

Fantastic work!
