Laser Cannon 3
Control a laser cannon that takes out the monsters that are trying to overrun your land! Your laser cannon is mounted to the edge of the screen, where it may be stationary or moving. Use your mouse to move the firing cannon and click it to shoot a cannon at the enemies. In later levels, your cannon can move. Use your up and down direction keys to move the cannon along the length of its mounting. This will give you more flexibility in being able to shoot monsters. Use the steel walls to make a ray bounce back and hit a monster that you can't hit directly. Each level, face more obstacles and more creatures.
