you use the normal story mode
well, the mode of story is more interesting. you should save more coins to unlock the level if you don't want to use dollars.
Use story mode.
you can use Guan Yu, but you have to unlock him in Shu Story Mode
you have to use story mode buddeh :)
You cant,BUT there is a glitch in the game where you can only use him in story mode.
No you can not you can only play as Jordan when you finish the Jordan challenge and unlock the mode or use a cheat to unlock the mode.
Unlock marth then use him to beat classic mode.
you cant but you can use him in story mode
If you want to unlock people in line 2 and 3 that you can use as partners complete story mode with jaden not as hard as it sounds just get 4 hearts
You must unlock Dong Zhuo by using Lu bu or Diao Chan on story mode or use Zhang Liao on story mode and when you did all of the level's it might say you unlocked Dong Zhuo for free mode or challenge mode.
I think you can play as Amy in story mode but you need to use Action Replay. You can play as Amy in 2 player mode, she is already unlocked. To unlock Amy in kart mode you have to successfully complete all of Sonic's stages and missions with the ranking "A". I hope that helps.
Complete story mode and use the stuff from story mode to create your level.
