About Sonic and the Black Knight

Sonic and the Black Knight is a 2009 platform game developed by Sonic Team and published by Sega for the Wii. A spin-off of the Sonic the Hedgehog series, it is the first and only Sonic video game in the franchise to not include the franchise's main antagonist, Dr. Eggman in any way, as well as the second and final entry in the Sonic Storybook sub-series following Sonic and the Secret Rings (2007), and involves Sonic being transported to the story of King Arthur by wizard Merlina, under the pretense that they are attempting to stop a corrupted Arthur ; however, it is later revealed that there was no corruption and they must stop Merlina's misguided attempt to prevent the legend's fate from occurring. Gameplay involves controlling Sonic around with the Wii Remote's motion-sensing functionality, particularly swinging around the sword to attack enemies and to move forward.
