The 1-Up theme is based on the unused 1-Up Theme from Sonic Adventure "Escape from the City (Classic)" is a pop mix of the original Escape from the City from Sonic Adventure 2. "Escape from the City (Modern)" is a rock theme similar to the original song for the Modern version of City Escape from Sonic Adventure 2. Stages Stages will be divided into 3 eras.

His voice as modern Sonic can be heard in demo gameplay footage thus far with a higher voice than in Sonic Free Riders and Sonic Colors. Classic Sonic will remain silent throughout the game, but will still show his personality through his actions and gestures. Cream the Rabbit and Vanilla the Rabbit Japanese voice actress Sayaka Aoki revealed on her blog that she has been recording some voice work for a game that will be released in the future as well (whether or not she was referring to Generations is unknown).
