This Method requires a second controllerLoad up a Run game with a second controller with the difficulty set to easy and rounds set to 5. Once in the game perform each attack with the account you want the achievement on.
AttacksPunch = Double tap
in the direction of the second character/controller
Thrust upwards (don't know actual attack name) =
+
(Whilst next to the second character/controller)
Butt Pound =
+
(Whilst next to the second character/controller)
I performed these multiple times and didn't unlock the achievement. Then I did an aerial attack on an enemy (cn_A then cn_X), and it unlocked.
It's not an attack listed in the controls menu, but if anyone's having trouble unlocking this one, try an aerial attack.
Perform all of these attacks (can be in the same round) on the second character/controller and the achievement should unlock.
