This multi-level action-adventure game takes players back 40 years to find Professor K.K. Renegade, who predicted that a catastrophic asteroid is headed straight for Earth. Select one of 5 intrepid adventurers from England, France, Germany, Japan, and the United States to conduct research in an area populated by creatures and conditions designed by the professor himself: venomous stone snakes, reptilian birds, and acid storms. The player must also correctly use curious but useful objects. Once you locate the professor, you must help him build an anti-asteroid deflector to prevent the destruction of Earth. You have 30 days to complete the mission.
