Hi! I'm kind of struck in mission 6. I got the gyrocopter and survived Ms. La Pette's attack. Now i want to pay her a visit too. I captured the last coal piles with the gyrocopter and buid a base, but i can't get my henchmen or any amphibious creatures through the cave Ms. La Pette is using for her attacks. Any ideas? It will take my single gyrocopter henchman a long time to get all that coal.... Thanks for your help.
