The world of Darwinia is a virtual themepark, running inside a computer network built by a computer genius named Dr Sepulveda. Darwinia is populated by a sentient evolving life form called the Darwinians. They are the product of a decades worth of research into genetic algorithms. Unfortunately, the systems of Darwinia have been overrun by an evil red Viral Infection. This Virus has multiplied out of control and must be stopped. Your task is to destroy the Viral Infection and save the Darwinians from extinction.
