Pirates of the Caribbean: The Call of the Kraken is an add-on game to Pirates of the Caribbean Online.
Plot
The game takes place many hundred (or less than hundred) years before the events of movies, online game, or any other plot-related merchandise to Pirates of the Caribbean. It tells the tale of how Davy Jones brought about his power to bind Calypso into her human body. Jones uses the power of the Kraken and the Journal of the Ancient Seas, to pursue the first Pirate Lords of the seas into lending their hand in helping bind Calypso. The player plays as the Kraken and has to travel to various oceans and wreck havoc to force the Lords into helping Jones. The story progresses as each Lord is subdued in this manner.
Game Play
The Kraken is commanded from a bird's eye view, to eliminate ships that come in her way. The ships vary from sloops to bigger ships. The battle is complicated, and is based upon the need to collect souls by destroying enemy ships. The usurped souls improve the Kraken's power. The souls are used on the various skills of the Kraken for attack, and at one point the player can master them all.
