You have two guns. One on your left and one on your right. Boxes are falling to you. Catch them before they hit you! When they are close to you tap to hit with the guns. Tap left to shoot with the left gun for boxes that are falling on your left...and tap right for the rest. 3 Lifes! Remember: Don't shoot when a box is gray (destroyed) or when no box is in the range of the guns (the bar - - - on the bottom). Don' t lose your bullets, otherwise you will eliminate your score. Good luck!
