The first announcement for the Nintendo Direct starts with a new trailer for Sonic Lost Worlds and ends with a release date for both 3DS and Wii U versions. Sonic Lost Worlds will be coming to both systems on October 22nd.
Sonic can be more freely controlled now and he gets a host of new power-ups and abilities, such as wall running, volting over obstructions and more.
There’s also an extra feature for the game as stated by Nintendo NA:
The Nintendo 3DS and Wii U versions will communicate through a local wireless connection.
It’s a really interesting mechanic and I’m curious to see how it will be implemented in the actual game. We’ll find out soon I suppose.
