According to the developper : "As far as BeckHAM goes, you have to kick the head TWICE, which is pretty tricky. Use uppercut (down, forward) as finishing blow to pop the head off, catch it, wait for an enemy to get closer, throw the head, jump kick it at the enemy, it will bounce upwards, jump kick it again.
It's not easy ;)"
