Sonic Lost World

Sonic Lost World is a 2013 platform game developed by Sonic Team and published by Sega. Part of the Sonic the Hedgehog series, it was released in October 2013 for the Wii U and Nintendo 3DS. It was developed as a partnership between Sega and Nintendo, who allowed downloadable content based on their properties as well as distributed the game in PAL regions; a port of the Wii U version for Windows without Nintendo content was later released in November 2015. Lost World focuses on the efforts of Sonic the Hedgehog to stop the Deadly Six, an alien tribe that serves as the game's main antagonists, as they seek to siphon the world's energy from the Lost Hex, the game's setting.
