Clear out the baddies by identifying and sending a missile to their location on the coordinate grid. Miss and they'll fire back taking down your shield some. Choose to play timed or untimed and on Quadrant I or on all 4 quadrants.
Use the on-screen number pad to plug in the X Y coordinate of the enemy and click the FIRE button to send a missile their way.
