Sonic Generations

Sonic Generations (ソニックジェネレーションズ Sonikku jenerēshonzu?) is a platformer video game for Xbox 360, PlayStation 3, Nintendo 3DS and PC. The game was made and released to celebrate the twentieth anniversary of the Sonic the Hedgehog series. The Japanese version has different subtitles: White Time and Space (白の時空 Shiro no Jikū?) for the home consoles, and Blue Adventures (青の冒険 Ao no Bōken?) for the 3DS version. All versions of this game can be played in 3D, but a 3DTV as well as a pair of 3D glasses are required for the PlayStation 3 and Xbox 360 versions, being the first game of the franchise to be played in 3D. It uses stereoscopic 3D with the involvement of a pair of screens in one.

Gameplay

The game features levels derived from twenty years of Sonic history, ranging from the Classic era, through the Dreamcast era, to the Modern era. There is a level taken from each mainstream 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. Modern Sonic's levels, on the other hand, carry on the current modern 2D/3D gameplay of recent titles such as Sonic Unleashed and Sonic Colors, featuring the Homing Attack, Freestyle Tricks, a Drift, the Stomp, the Light Speed Dash, and the Boost. Red Star Rings return in the console version. Five can be found in each Act, and collecting them unlocks extras such as music, art, and movies.

The hub world starts out at White Space, but opens up more as the Sonics pass through more levels. The Hub worlds are only playable in 2D, so they are not free roam like they were in Unleashed. One character is rescued in each stage. Characters rescued will stand outside the entrance to the stage, and they can be talked to. Also, there is an area above the entrance to the main stages where the player can access Challenge Acts and rival battles. Bosses are accessed through special areas known as "Boss Gates", found at the end of each era.

The handheld version, unlike the console version, makes the Modern Sonic gameplay similar to Sonic Rush, while also featuring Special Stages based on Sonic Heroes. Some bosses are played as Classic Sonic, and some are played as Modern Sonic. Act 1 is played as Classic Sonic and Act 2 is played as Modern Sonic, and there are ten missions per level.
