The game's story mode features a navy captain who is sent undercover to retrieve "The Key of Dreams", a dangerous artefact, from the hands of the famous pirate Blackbeard. To do this he must travel to seven different locations in 3 different parts of the world, finding out where Blackbeard is located and eventually battling him.
Recruiting new crew members, such as lookouts, navigators and master gunners to increase the skills of your ship, is of course also a necessity. You can also use a variety of weapons, like sea mines, rockets, flame cannons, and of course regular cannons to battle the various opponents you will face on the seas. The story mode has a total of 10 levels.
Aside from the story mode there is a Skirmish mode, with 35 small stages where you must battle 2 or 3 AI opponents. There is also a multiplayer battle mode, where 2 to 4 players can battle it out with each other (Multiplayer has the same 35 stages as Skirmish mode). In multiplayer mode you can also select some stranger ships, such as enchanted ice ships and ghost ships.
The 15 screens of both the story mode and multiplayer mode can be seen on the game's page (You can only see 10 on the actual game page - Click on one and you can look through them all).
Pirates: The Key of Dreams is, according to Oxygen Games, the prequel to their DS game Pirates: Duels on the High Seas, which comes out later this week. The Key of Dreams is scheduled to hit WiiWare on the 30th of this month. The price of the game is still unknown.
