Defeat 50 Enemies using Super Wushu
Weapons have a "Super Wushu" ability in which the user becomes powered up and able to do attacks quickly. Some the abilities that may be tied to this combat style include:
Gun Super Wushu: Players leap in the air with weapons drawn. While time slows around them, they are able to unleash a barrage of shots against multiple targets. Once time reverts to normal, the results of the barrage occur.
Klonk Super Wushu: Used in conjunction with the Klonk Fist, this allows players to charge between enemies, repeatedly striking with a charged-up fist.
Super Melee Wushu: A melee ability that allows players to engage in a quick series of slashes with their blade.
As the description states, defeat 50 enemies using this ability to unlock the Wung-fu Master achievement.
