Like in the Dreamcast version, the player assumes the role of the GG's, a gang of graffiti-spraying youths, led by Beat (who is also the first playable character). The Rokkaku group and the Tokyo-to construction conglomerate have teamed up to clamp down on the "rudies", the game's term for the law-breaking teenagers. The object of the game is to "Tag" certain parts of the surroundings before the time limit runs out or "before the indomitable array of cops arrives".
