Somewhat difficult to do but if you pace yourself and only allow a few enemies to come on screen at a time, you will have a much easier experience. Don’t pick up any weapons, and use the + elbow combination. When you reach the first Big enemy and the guy holding the bat, run around the making them follow you. If you can hit them both at the same time that is good. Continue to run around the screen until both enemies are dead. The next area is where it gets a tad more difficult. Move forward slowly bringing out the guy with the knife. Take him out, and move forward a little more. If you did it right, only the one enemy will come out. Take him out and move forward more to face the final boss. Continue to use the + back elbow while moving around the screen and you should get this achievement.
