Attack From Mars Cheats

Shoot the ball up the Big-O-Beam ramp on the left side. When you hear a cow mooing, press the Launch Ball button. You will hear a moo sound again. Now, the second time you get to Video Mode after this, you will be attacking cows instead of flying Saucers! Destroy all the cows and the giant Mother Cow will appear!

Before pressing the Start button, hold down both flippers and the Launch button for 10 - 15 seconds. This will let you enter Tournament Mode. We still haven't figured out what this does differently, but at least now you know it's there.

Hold the left flipper before launching the ball. While holding the flipper, get the skill shot. A rather easy task. The "Force Field" blocking the UFO will drop. This works any time you are launching a ball and the "Field" is up.
