Play Laser Cannon 3 Level Pack
Use your laser to shoot all of the monsters in each level by aiming it with your mouse and left clicking. Move your laser, when it is on a metal track, up and down the track with your WASD keys so you can get better positioning. Use metal plating, bombs, and spike drops in order to help you successfully hit. Open levers by shooting them and activate metal spin balls by shooting them. Get rid of all the monsters in the level to move on.
