Over the years Sonic the Hedgehog has had a torrid time making the leap from a two dimensional world to 3D, so much so that fans have taken it upon themselves to make amends. One fan who goes by the name of Xaklse, created a 3D Sonic Games Development Kit which he’s finally put to good use. Green Hill Paradise: Act 2 appears to be shaping up into an incredible game with plenty on offer, and an awful lot Sega could be taking notes from too.
