3D Sonic the Hedgehog

3D Sonic the Hedgehog is a downloadable port of the original Sonic the Hedgehog, produced for the eShop service, and is part of the 3D Classics line. This game utilises the 3DS's stereoscopic 3D vision and some extra features, but is otherwise pretty much identical to the original Sonic the Hedgehog.

Plot
The plot is essentially the same as the original; Sonic must save all the animals of South Island that have been captured by the game's main antagonist, Dr. Ivo Robotnik, who had transformed the animals into evil robots. As well as saving the animals, Sonic must also obtain all the six Chaos Emeralds stolen by Dr. Robotnik.
