Instructions for Space Invaders
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!
