Following the ill fated first ORRT mission to Venus, no one went back to look for survivors. But someone did survive. Now renamed General Amadeus, and missing one hand to a giant Venusian dinosaur, the old Commander has lived the last 15 years with only robots for company. When the return mission landed, Amadeus was sent mad with rage, and he sent his Shadow Bot to capture as many of the new team as possible. Back at his lab Colonel Abrams and Captain Pythagoras are held in a cage, whilst poor Space Ranger Falco is having his brain manipulated by Amadeus' fiendish Venusian rock crystal.
