This design is the cover for Sonic Adventure 2. The cover has a constant theme of two forces clashing with each other. This can be seen with the background's color, with the color on sonic's side being a blue sky, while the color on shadow's side being a red tinted view of the earth, and then there is a purple space in between. This represents all three campaigns in the game. Those are The hero story, where you play as the hero's, the dark story, where you play as the villains, and the last story where both sides both sides join together to save the world from disaster.
