Easiest way to beat the last mission
If you have unlocked it, use the Surfin' School Bus with the Energy Shield gadget. When you start, you have to go through a mine field. Keep using your energy shield. When you meet Rupert, you must disable him. Use your Energy Shield until you get a gadget that you can attack with. Disable Rupert and his henchmen if they get in your way. Then, you have to go destroy the computer with the special gun. Find the special gun and destroy the computer. Otto will appear and drive off. You must chase him. There will be more mines, so use your energy shield again. When you catch him, disable him with your special gun because it will take him out with two or three hits.
