SEGA just revealed a few more snippets of information about Sonic Generations on 3DS, and it seems the game will include some oft-requested features.

AndriaSang reports that SEGA has confirmed two-player online competitive play for the title, sparking speculation there'll be a second playable character in the game besides the Classic and Modern versions of the hedgehog.

The game will also feature StreetPass support, though no further details on this were given. We'd expect sharing of best times at the least, but SEGA will go into more detail at a future date.

A Sonic Heroes-like Special Stage was also revealed, which should look pretty trippy in 3D. Check out some decidedly 2D screenshots in our gallery below.
