Rolling... Rolling... Rolling Thunder

Is there a way to extend Rolling Thunder’s reach?

I was on Xbox Live the other day matched up against a pretty good Dudley, and everytime he’d do Rolling Thunder, it looks like he adds an extra duck. And it’s not a ducking to special, it comes after the SA start up. I’ve been trying so hard to figure this out, maybe I was just mistaken from the beginning.

Hold 3 punches.

Awesome thanks.
