As a pirate, you've gone to find the sunken treasure of the island of Tortuga! Other pirates have heard about what you're doing and they want a piece of the action, but you'll be the only pirate to rob the place blind! Waves of boats will come through and try to get past you to Tortuga. You have to place cannons that will take their ship down before they even see the shore. There are seven different types of cannons on the right side of the screen. Click on one to buy it. Click on an X on the screen to place it there. Click on waves and put them in front of enemy boats to slow them down.
