The 3DS joins the 360 and PS3 as a future home for Sonic Generations, the upcoming celebratory mishmash of Sonic past and present. All versions are set to come out next November, to coincide with the franchise’s 20th anniversary. The 3DS will also share the same time-traveling storyline that will have players reliving the original’s levels in both 3D and 2D. In addition, the 3DS version will include unlockable special stages, StreetPass support (for players to gain new content when they pass other players), as well as a two-player versus mode.
