Sixty-five million years ago, the dinosaurs mysteriously disappeared from Earth. It was believed that they had become extinct. In reality, they had burrowed deep into the Earth and then evolved further into super monsters. In the year 2000, the humans of Earth were amazed and terrified by the greatest catastrophe ever known to mankind: the re-appearance of the dinosaurs. Under the direction of their Emperor, Tyranis, the dinosaurs-turned-super monsters now seek to destroy mankind and take over the world.
