how do i play story mode?

i bought the game used and i came without a booklet. also is there a way to make the computer A.I a little easier to beat? ichanged the difficulty to easy and i still can't beat the computer.

thanks,

Umm, if you can't beat it on easy... well... eh... easy isn't hard, my firend has it and I never had problems with easy =/

Erm, I have it on medium and fidn it pretty easy so I can't see how you would find it any harder.. plus your alot older then me

Practice my friend..
