Sega has announced an all-new Sonic adventure exclusive to Nintendo Wii.

Sonic and the Black Knight is part of the storybook series of games that began with Sonic and the Secret Rings, and sees Sonic thrust into the world of Arthurian legend armed with just a sword to save the day.

Created by the Sonic Team in Japan, there are a series of Arthurian-inspired locations for you to guide Sonic around, not to mention a whole host of characters - new and old - for you to get to grips with.

"After the success of Sonic and the Secret Rings we're delighted to announce a second title in the Storybook Series," said Gary Knight, European marketing director, SEGA Europe, "Following Sonic on his way to knighthood will excite players of all ages."

Sonic and the Black Knight will be out for Nintendo Wii in Spring 2009.
