The stage mostly remains the same as its Brawl iteration. However, the checkpoint "reached" takes less attack time, making it harder to camp with. The checkpoint will now make the classic sound effect from the Sonic games.
This stage takes from the very first Sonic the Hedgehog game's first stage of the same name. Each detail of the stage is meant to capture the essence of Sonic the Hedgehog (not the Sonic '06 game) and cameos Miles "Tails" Prower, Knuckles the Echidna, and Silver the Hedgehog.
These eight tracks are from Sonic games prior to the Dreamcast.

- The reason for the "Modern" tracks going to a new Sonic stage is the director's idea that both "eras" of Sonic games would better be embraced with a "Classic" stage and a "Modern" stage for the Sonic franchise.
