It really does sound like an underground chase in a futuristic world. The overall beat of the song was pretty cool. Everything you used on this complimented each other very well. I also liked the parts (like around the fifty second mark) where it just has somewhat of a dramatic pause. That instantly made me think there was a pause in the action where somebody's hiding from their chaser right before the find them again. Then the action starts again with the beat. This was well put together. Nice job.
