It’s called Sonic Colors and it’s just like it sounds. When Sonic obtains a certain color, it gives him a certain power. For example, cyan turns him into a laser, letting him shoot right through obstacles.
The Wii version will feature a combination of 2D and 3D gameplay, and the DS will make heavy use of the touch screen.
I know we don’t know much about it yet, but I think it looks pretty good. Yes, 3D Sonic games have been largely terrible in the past decade, but in recent years, the Wii exclusives have outshined the other console versions. So I’ll keep my hopes high.
