Sonic Generations, called Sonic Generations: Shiro no Jikuu (ソニック ジェネレーションズ 白の時空) in Japan, is a platformer commemorating Sonic the Hedgehog's 20th Anniversary. Developed by Sonic Team for the Xbox 360, Playstation 3 and PC, the game allows players to experience both "classic" and "modern" Sonic gameplay styles. Classic gameplay in Generations is reminiscent of the side-scrolling platforming first introduced in the original 1991 title Sonic the Hedgehog, while the modern side of Generations sees the forward-moving gameplay of the 2006 title Sonic the Hedgehog and other recent titles. Sonic Generations for the Nintendo 3DS was developed by Dimps alongside this title.
Sonic Generations allows players to control both the pre-Sonic Adventure and post-Adventure designs for Sonic the Hedgehog and features remastered levels from Sonic's previous adventures. The game is divided into three eras: the Classic Era (pre-1998), the Dreamcast Era (1998-2005), and the Modern Era (2005 onwards) - "Classic Sonic" playing through the levels from a 2D (or 2.5D) "classic" perspective, "Modern Sonic" tackling them in a 2D/3D perspective, similar to Sonic Unleashed and Sonic Colours.
The game was first announced in a teaser video posted by Sega on April 7, 2011 on Sonic's official Facebook page. The game was announced for both the Xbox 360 and PlayStation 3 and was scheduled for a 2011 release. An announcement of Sonic Generations for the Nintendo 3DS later appeared in an issue of the Nintendo Power magazine, paired with a November 2011 release date for all platforms. At E3 2011, SEGA revealed a trailer revealing City Escape from Sonic Adventure 2, with a further trailer appearing in mid-August detailing other levels. On October 11, 2011, Sega confirmed that Sonic Generations will also appear on the Steam platform for PC; Sega of Japan has yet to announce a Japanese release of this version (if one is even planned).
A fourteen-day demo was released to Xbox 360 and PlayStation 3 consumers on June 23, 2011, the official date of Sonic's 20th anniversary. A second demo was released October 18 on Xbox Live, October 19 on the European Playstation Network, and October 25 for the Playstation Network in North America.
The gameplay is split into two separate gameplay styles, separated by the character used.
The Modern gameplay style takes place in 3D with transitions to 2.5D. This gameplay style represents Sonic's more recent titles Sonic Unleashed and Sonic Colors, where you use the Sonic Boost and the Homing Attack to advance.
Each level and boss in Sonic Generations is reminiscent of one previously appearing in the Sonic series.
