Sonic: Lost World is a new 3D Platformer from SEGA being published by Nintendo. Sonic Lost World was released on October 29, 2013. It features a new set of antagonists known as the "Deadly Six".
For the longest time, Shadow the Hedgehog was technically a spin-off, but thanks to Sonic x Shadow Generations, I suppose it’s now canon. Shame, since this game ... time, Lost World was stuck ...
