Backpack cheat:

The Diver can take two other men in his backpack. When his boat is in the water,

pick it up using the hand. If you let two commandos step into the boat st the

right moment, they’ll go with the boat, into the backpack of the diver/spy.

Now you can swim as a diver to the other side of the water, which is much less

suspicious then when you use your boat. But when you die, the men you carry

with you will die too! So be careful!
