Emerald Coast is the fourth level in the Nintendo 3DS version of Sonic Generations, and an adaptation of the level Emerald Coast seen in Sonic Adventure. Modern Sonic's take is virtually identical to the original, while Classic Sonic takes a more platforming approach to the stage. Both have a chase with the famous Orca at some point in their respective acts.
The Classic Act is based on the first half of the original Emerald Coast, complete with the Station Square resort in the background at the start. Soon after the resort is a part of the beach that resembles Neo Green Hill Zone. After this part, Sonic goes through rock structures and is soon chased by the orca. After this chase, he passes through another rocky part with two paths, one composed of water and other parts following the wall. The level ends similarly to the original.

The Modern Act begins differently from the first Act, in which Sonic runs along a rocky part and jumps through Dash Rings and Rainbow Rings. There are platforms that require the use of the Boost, thus reaching higher ground level. At the end of the Act, Sonic is chased by the orca, eventually engaging a quick-time event where the player must press the button three times so that Sonic doesn't get eaten.
