Sonic Generations 3DS revealed

Exclusive content for portable platformer.

Following much speculation last month, Sega has officially announced a 3DS version of forthcoming platformer Sonic Generations.

The handheld version of the game is being built specifically for the 3DS and boasts a number of features that won't show up in its PlayStation 3 and Xbox 360 equivalents, including an unlockable 3D-friendly 'Special Stage'.

You'll also be able to collect new content from other players and unlock bonus material via the system's StreetPass feature. On top of that, there's a new two-player versus mode as well.

As revealed back in April, Generations sees Sonic and his friends pulled back through the ages by a mysterious force which is causing chaos across the universe by creating 'time holes'. It's all essentially a high-concept excuse to blend classic 2D Sonic gameplay with that of the more recent 3D titles.

"Sonic Generations for Nintendo 3DS will combine brand new technology and 20 years of Sonic the Hedgehog videogame heritage," said brand director David Corless.

"Couple this with the ability to play as both Classic and Modern Sonic and you have the perfect gaming celebration for the landmark anniversary of our much loved mascot."

The 3DS version will launch in tandem with its PS3 and Xbox 360 counterparts this November.
