Best price I have seen for this game online so far. Great game going by reviews by IGN and others online, a must buy for Xmas!
Shopto are also very quick with their free deliveries :)
"Sonic Colours sees Sonic accelerating to adrenaline-pumping super speeds and blasting through obstacles in ways never before seen in a Sonic game. The alien Wisps in Sonic Colours each have a unique "Colour Power" that, once freed, Sonic is able to absorb whilst speeding through the various theme park inspired planets.
The Wisp energy enables Sonic to create new paths through the stages by drilling through the ground (Yellow Drill) for example, or speeding through the stage as a laser (Cyan Laser). Stringing the Wisp power ups together creates a combo that increases Sonic's boost gauge even more quickly. Exclusive Wisp power ups will be available for both Wii and the Nintendo DS versions, ensuring a unique and super speedy gameplay experience for Sonic fans everywhere."
