The game is based on a cross between two very different, but very cool themes: Pirates and Romance of the Three Kingdoms (a.k.a what most people in the west recognise as the source material for Dynasty Warriors).
The game features over 300 characters of all kinds of animal types penguins, cows, monkeys, eagles and dragons.
And the lead character is a pirate penguin. A pirate penguin!
There's going to be a trilogy to this series, which should mean plenty of swashbuckling awesomeness. Welcome back to Nintendo, Marvellous.
