SEGA has just officially announced the title of their new Sonic game for Xbox 360 and PS3. As leaks and rumours suggested, the game is titled Sonic Generations and will be released Holiday 2011. SEGA’s also issued a press release revealing details about the game and its plot, as well as some screenshots and a trailer.



Sonic will be playable in his 1991 "Chubby" incarnation as well as the sleeker, modern Sonic. The game will include call-backs to environments from the older Sonic games, rendered in HD and playable in both classic 2D and the modern 3D modes. Both Sonics also come equipped with the full complement of identifiable Sonic moves. Finally, the announcement promises an "interactive new menu system" to interact with characters and gather treasures. Yes, seriously.

As the teaser suggested, Generations will feature playable versions of both the modern "green eyed" Sonic and the pot-bellied 1991 incarnation. It's set across Sonic's three defining "eras" and features reimagined classic environments that will come in 2D or 3D flavors.

Each Sonic has his own special moves -- Classic Sonic will have the Spin Dash and Spin Attack while modern Sonic will have his Homing Attack and Sonic Boost. SEGA also promises an interactive menu for "complete immersion" and a number of bonuses and popular characters that are revealed throughout the course of the game.

"By having the classic 1991 Sonic that many fans know and love team up with his modern day incarnation, we are bringing back the nostalgia of the early days of Sonic and combining it with the innovation and stunning HD technology of the modern gaming era. Sonic Generations will bring to life the last twenty years of Sonic's universe in a truly unique and imaginative way"
