this is story related and cannot be missed.
all you have to do is double tap A to move out the way from him throwing dead people and charging you. after charging 3 times he grabs his head and the achievement pops.
if you want to practice combos after a charge, you can here because you can hit the pause button to restart checkpoint if you take damage.
i think i got a 1000pt bonus when i just avoided him and took no damage. but maybe you get the 1000pts regardless.
either way, you can't miss this achievement.
