The evil space wizard Krohn has mastered the power to control a black hole, and plans on using this power to control the universe. You are an explorer on assignment in a remote corner of the universe. You have just been reassigned to fight Krohn since your ship, the Millennium Orb, is the only space craft cabable of withstanding Krohn's black hole. To defeat Krohn, you must get past 30 different chambers blocking the path. On the left and right side of each chamber are force fields which you must maneuver to keep the Millennium orb within the chamber.
