-----------
On the Indian Ocean board go to the "double loop" room (there are two giant loops standing up on the floor). Pilot your craft between the two loops and turn toward the wall covered with starfish. Shoot missiles to reveal a secret passageway. Go down passageway and find a room with four crystals on the wall. Shoot each of the crystals until they shoot out shiny disco balls. Once all four are activated, an extra man will appear in the center of the room.
On the Mediterranean board blow up the tall statue and grab some pilot missiles. Dive deep in front of the statue and go through the doorway (it's below critical depth and it has a health in it). Now go up until you hit the ceiling. In front of you is a door with a large keyhole. Shoot a pilot missile through the keyhole (use regular missiles to tell when you're lined up right). Once the pilot missile goes through the hole, guide it around the first corner and hit the pot on the stand. This opens the door. Swim down the tunnels into the room with the statue. Up top on the shelves is a red pot that contains a yellow key. Get the key. Now swim all the way back out and go to the upper temple (the one with the female statues in front). Now that you have the key, the door will open. Blow up the altar on the floor and go down the secret tunnel to the extra man. Invincibility
