This one is exactly like "Reversals Only", except instead of reversing attacks, you can only use directional attacks. To use a directional attack, spin in a circle. Avoid starting from the top though, as you will sometimes try to grab instead of attack, which voids the achievement. It's a huge pain to do this, though, as you cannot finish off your opponent with your attack, because only the environment will finish your opponent off.
Choose whoever you want for this achievement, as there are no best characters to use for it. Use the Executive Suite as your area, and Sitting Sidewayz as your theme if you want the bass to be constant. Focus on trying to get your opponent into the speakers in the back, which is easier said than done. Depending on which way you spin the , your attack will go in a different direction. Where your attack goes, it will send someone in that direction. These change depending on the camera angle, and which side you're on, so try and figure it out as you go.
