The year is 1937 and you are Rex Chance, renowned world adventurer and war correspondent. You have spent your life exploring the wilds of Africa, the ice shelves of Antarctica, and the sultry jungles of the Amazon. You've seen every beast on earth... or so you thought. You've just received word from your long lost father, scientist Dr. Eric Chanikov, who disappeared many years before. Suddenly, he now begs to see you. So you fly to the Isla Variatas in the South Pacific where he works in the employ of wealthy industrialist Upton Julius. But what begins as an innocent reunion quickly turns sour as you come face-to-face with the Sigma Technology.
What is the Sigma Technology? Imagine possessing the ability to combine any two animals into a single creature. Flying elephants, giant ants, amphibious sharks... anything you can conceive. The possibilities boggle the mind! What benefits might it bring? What evil might be wrought?
