Sonic will be dishing out all new parkour moves and special Color Powers( returning from the game Sonic Colors) to stop the creatures. The Wii U Gamepad will allow you to control the Color Powers by tilting, touching, and aiming. It will also allow you to play the full game on just the Gamepad. The 3ds version will also have exclusive stages and Color Powers not found in the Wii U version.
Here's what Hiroyuki Miyazaki, the Chief Content Officer of Sega of America said in the press release....
" We are proud of the strong relationship between Nintendo and SEGA and look forward to continuing success with Sonic Lost World on Wii U and Nintendo 3DS."
"The game marks an evolution of the Sonic series and fans - both old and new - will be excited by a story which sees two of video games biggest adversaries, Sonic and Dr. Eggman, joining forces for the first time to help defeat a new deadly threat."
