You can try out Sonic Generations on PS3 and Xbox 360 in advance starting today. No such luck for the 3DS version of the game, but at least Sega was good enough to share some screens and details today.

Access the screens in this gallery.

In Japan, the 3DS version of Sonic Generations is titled Sonic Generations Blue Adventure, as opposed to the "Sonic Generations White Space & Time" of the PS360 version. While the two versions offer the same choice of Classic Style and Modern Style play options, they're otherwise quite different. Outside of the Green Hill Zone, which is pictured in the gallery, the 3DS title has all unique stages.

Other features of the 3DS version mentioned by Sega today include:

• The appearance of Big Arm, Sonic the Hedgehog 3's final boss
• Two player internet competitive play
• Street Pass support
• A Special Stage that will be familiar to those who played Sonic Heroes

Details on these areas will be shared in future updates.
