Sonic Generations

Sonic Generations (ソニック ジェネレーションズ) is an upcoming game for Microsoft's Xbox 360 and Sony's PlayStation 3. The game is made to celebrate the 20th Anniversary of the Sonic the Hedgehog series.

Plot
Sonic's universe is thrown into chaos when a mysterious new power creates "time holes" which pull Sonic and his friends back through time. As a result, he encounters some surprises from his past history including Classic Sonic, Sonic as he was in the past.

Now, Modern Sonic and Classic Sonic must defeat this strange new enemy, save their friends and find out who is really behind this diabolical deed.

So far, only Modern Sonic and Classic Sonic have been confirmed to appear, but other characters have been hinted to make appearances. The producers have mentioned that they "will think about the game's cast, so please wait for it."

The writers for the story are credited as Ken Pontac and Warren Graff of Happy Tree Friends fame. They also worked on Sonic Colors and MadWorld.

Gameplay
The game features levels derived from 20 years of Sonic history, ranging from the Classic era, through the Dreamcast era, to the Modern era. There will be a level taken from each Sonic game to represent the different times. Each level can be played with either Classic Sonic or Modern Sonic, each taking their own routes throughout the level. Classic Sonic's levels are strictly two dimensional side scrolling stages, using classic moves like the Spin Attack and the Spin Dash.

Hub worlds like the ones in Sonic Unleashed have been hinted at.
