Thanks to MarcelloF of the SSMB, we can reveal that Special Stages and Chaos Emeralds are in the DS version of Sonic Colours. MarcelloF attended Gamescom and recorded the above footage of the Special Stage. Those who have played the original Sonic Rush on DS will be familiar with the touch screen controlled half-pipe, but this time instead of collecting rings, you are collecting certain coloured spheres.
MarcelloF has explained the Special Stage and more at the SSMB:
First of all: Sorry about the low quality and lack of sound. We we’re using the camera of my friend’s mom and we didn’t know it didn’t record sound.
As you can see I was pretty noobish at the start because I didn’t know what to do. After a bit the Nintendo rep told me I had to collect the spheres of the same colors as the top screen. The rainbow ones can be collected at any time. And then there were checkered ones, that if you collected all of them you would get a 10 sphere bonus.
I didn’t film this, because I didn’t know until we stopped filming, but you get ranked in the Special Stages.
I have some other info that I don’t have on film.
Planet Wisp is Level 4.
Sonic’s model is a bit different from the other two Rushes. He’s much darker and unlike SRA his spindash has the classic form
Thanks again to MarcelloF for this.
