Update: Screenshots of the Wii U and 3DS version and a preview with loads of details have been uploaded to IGN. The preview can be read here, the screenshots can be found below.
IGN just uploaded the debut trailer for Sonic Lost World, showing what the six guardians look like (surprise: they’re evil aliens!), but more importantly the new gameplay style. This isn’t just more of the same of what was seen in Sonic Unleashed, Colours and Generations. This also adds elements from Super Mario Galaxy and the cancelled Sonic X-treme into the mix.
Also note-able is that the game has a new beautiful plasticine-like style. Those who have wanted an incredibly stylized Sonic game (like me) will probably be very pleased by how this turned out. In addition, Flickies are back. Sonic Lost World will be out this fall exclusively on Wii U and 3DS.
