The premise of the game is simple. Using the creature chamber, players can combine two animals to form a new "super" animal - combining the best traits of the source animal and resulting in something quite different and much better than the sum of the two parts. You can also use any animal you have found the DNA for - whack a piranha head on a donkey, for example, or slap a snake on a hawk. The idea is to build ideal combinations that result in a genuinely useful unit - a flying spitting cobra, for example, would be killer - as would a piranha that could travel at 80 miles an hour, on the tail end of a cheetah. Get the picture? You can tinker with which set of legs or which animals to use for hours and hours and hours - there are so many options available, this part is almost a game in itself!

All these creature manipulation shenanegans are set against a backdrop of 1930's science, on a chain of islands just off the coast of Chile. The story is that your character, Rex Chance, receives an urgent message from his father, who has been studying advanced DNA applications. He rushes off to the island, only to find that things have taken a turn for the worse and your Dad's evil boss has set about stealing the research and generally getting up to no good. It's up to you and Lucy Willing (who is) to save the day.
