I left out three names and two styles for reader input.
After choosing you would battle the seven other remaining characters in their home arena. The final Battle would be against the secret dance master. Who would end up being Michael Jackson! Who Else? If you beat him you are crowned Dance Master and save the world from him ever making another CD.
The dancing moves of each character would be their fighting moves (ex. BreakDan C. would do a flare to kick other players in the face).
Things to unlock:
To unlock a character’s arena for Mutiplayer Mode you would have to beat the game on any difficulty level with the player who’s arena you want unlocked. To unlock secret arena 1, you would have to beat the game with all characters on the difficulty setting EASY. To unlock secret arena 2, you would have to beat the game with all characters on the difficulty setting MEDIUM. To unlock secret arena 3, you would have to beat the game with all characters on the difficulty setting HARD. After beating the game with all players and all difficulty setting you would unlock the playable character Michael Jackson.
