Pirate Legends TD can't quite match the quality of the game it aims to duplicate, but it comes close enough to consider.
Wp - "Pirate Legends TD is a new tower defense game for the iPhone and iPad. This one adds a few twists to the already well-established genre that was pioneered by the old school Desktop Tower Defense game way back in the day. In this game, your goal is to use your pirate ship, a number of different defense towers, and all kinds of other weapons in order to stop the enemy pirates from attacking and destroying your ship."
Another interesting free for a limited time iOS game. This time it's about Pirate Legends!
