Zak McKracken and the Alien Mindbenders

It's 1997, and the world is a dumber place than ever... Space Aliens have built a stupidity machine that's slowly reducing everyone's IQ to single digits. Worse yet, the only person who can stop them is Zak McKracken, reporter for the disreputable National Inquisitor, who dreams up stories about carnivorous cantaloupes and vegetarian vampires. They've taken over the phone company... Sure, it sounds like another one of Zak's tabloid fantasies. But while most people wouldn't believe him, he finds three who don't need convincing--Annie, Head of the Society of Ancient Wisdom, and her friends, Leslie and Melissa, two Yale coeds who traveled to Mars in their modified van.
