UPDATED!!! Up and down arrow to move the king. A to fire shotgun. Can be fired every 1.5 seconds. S to fire assault rifle. Can be held down for continuous fire. D to fire continuous beam. Takes 5 seconds to charge. Try to eliminate the red squared before the reach the line.
PRO TIPS: Move while using the beam to make it follow you, and eliminate many enemies. Use the assault rifle as a sniper. If they are grouping up, use the shotgun.
