The natural balance of the Earth is in disarray, as the world’s deserts have
flooded, rivers have dried up, and cows are flying. As the player discovers,
it turns out the planet is managed by one giant machine, run by a few World
Works engineers deep inside the planet. In their attempt to give the world a
“tune-up,” something has gone wrong, and it’s up to the player to travel to
the Earth’s core to figure out why. It’s at the center of the world that the
player discovers a strange hybrid species of Mechanimals — part animal, part
machine. Encountering many colorful and memorable characters, you must assist
four Mechanimals with their problems to restore the planet to its normal,
functioning state.
