The civilization on the planet Avaron is by far more advanced than that of the Earth. People developed special biogenetical creatures - giant flies, crabs, and other animals. Unfortunately, those monsters rebelled against the Avaronians and threatened to conquer the planet. It is up to you to save the planet Avaron from the invasion!
