You can move the laser base using these controls on the keyboard:
Space Bar = Fire laser
Left Arrow = Move left
Right Arrow = Move right

If you hit the UFO, you're rewarded with a "mystery" bonus score. It's game over after 3 lives, or if the invaders overrun the barracks. And you only get one shot at a time, so make sure you hit that target!

You need the <a href="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" target="_blank">Flash 5</a> plugin to play this game.
