Green Hill (Sonic Generations)

Green Hill (グリーンヒル) is one of the stages of the 20th Anniversary celebration game Sonic Generations. This level is part of the Green Hill Zone from the original Sonic the Hedgehog for the Sega Mega Drive, and part of the Classic Era.

Act 1
Classic Sonic's rendition of the well known zone consists of the young hedgehog running through the section at pacing to high speeds running up downward-vertical spirals and running on ceilings and platforming on wooden swings while bouncing on springs to the nostalgic end level signpost.

Act 2
Modern Sonic's take on the level begins with him pacing and eventually speeding through Green Hill performing extreme "Combo Tricks", grinding, and blazing through by using his boost move (only available to Modern), going up half loops and doing dangerous and sometimes unorthodox ways to get through. His levels focuses on the newer generation, taking elements from Sonic Unleashed and Sonic Colors, by performing Combo Tricks, and going to extreme treacherous areas. After pacing throughout the level he comes to a cave where a gigantic Chopper starts destroying the rails Sonic is Grinding on. Afterwards, a bit more platforming must be completed before the end of the level.

The handheld version is completely different, being on the Nintendo 3DS, it is in stereoscopic 3-D and it's based on the Sonic Rush series. All that is revealed about the level is that there will be rails "to be grinded" and also that when the end comes up Modern Sonic must smash through a giant totem pole, then the camera swings around in front of the him to show the rest of the pole toppling behind him, using the amazing 3-D. The level design is similar to the Sonic Adventure 2 version of the level.

Trivia

 * In the Classic Sonic version, its layout in the PS3/360/PC version is a mix between Green Hill Zone from Sonic the Hedgehog with loops, rotating and breaking platforms, and Emerald Hill Zone from Sonic 2 with the addition of corkscrews.
 * The stone totem poles featured in this level seem to be the same ones found in Sonic & Sega All-Stars Racing's Seaside Hill.
 * Comparing the PS3/360/PC version of the first act in Green Hill Zone to the 3DS version, the console version of Act 1 looks similar to the original Green Hill Zone in the beginning, but the rest of the level looks more new than the original Green Hill from Sonic the Hedgehog. In the 3DS version, Act 1 of Green Hill Zone looks identical to the first game; only that is in 2.5D version.
 * This is one of the only stages in Sonic Generations to be in both versions of the game (PS3/Xbox/PC & 3DS) the other being Casino Night but only through its Downloadable content.
 * In the sign post at the end of the level, on the PS3/360/PC versions it shows Classic Eggman while on the 3DS version it shows Modern Eggman.
 * A demo for Modern and Classic Green Hill was released on October 19.
 * The modern version of Green Hill seems to be the only classic level that isn't falling apart (the modern versions of Chemical Plant and Sky Sanctuary are falling apart).
 * In the modern version of this level on the Xbox/PS3 & PC there is a cameo of some choppers near the end.
 * In the 360/PS3/PC version, Green Hill is one of the two zones to have a "Boost" version of the Modern song, the other being Sky Sanctuary.
 * Buzzer's appear in this stage even though they didn't appear in the original game.
