Sonic and the Black Knight is a 2009 platform video game developed by Sonic Team and published by Sega as part of the Sonic the Hedgehog series. The game was released on the Wii as the second entry in the Sonic Storybook series, following Sonic and the Secret Rings (2007). Set in the world of King Arthur, the game combines Sonic's trademark speed with a new sword fighting system, utilizing the Wii Remote's motion-sensing functionality.
Sonic and the Black Knight received mixed reviews, with praise for its graphics, presentation and abundance of bonus content, but criticism of the game's controls, swordplay mechanics and multiplayer aspect. Sonic and the Black Knight was de-listed from retailers in 2010, following Sega's decision to remove all Sonic series titles with sub-average Metacritic scores in order to increase the value of the brand.
