As you are in the R.S (Robotic, Soldiers) you have got to achieve what you have been trained to do: fight the Ice King When your Minigun Ammo reaches 100, press your RIGHT ARROW and Left-Click to shoot. SPACE key to reload. Ice King will shoot 25 Ice Bullets at a time, each dealing 25, so 125 every time and 500 in total! HAVE FUN!
ENJOY
