I actually downloaded San Andreas when it was put on the store but I haven't finished it yet. Basic move set:
Square: Melee attacks (baseball bat, fists etc)
Triangle: Gun attacks (pistol, SMG, AK)
Taunts: "You only had to follow the damn train CJ!" "Special agent Big Smoke!" "I AM A SUCCESS, CJ! I HAVE NO REGRETS! I CAN"T BE TOUCHED!"
Supers: Level 1: attacks with a baseball bat saying "you came to wrong house, fool!" Level 2: rolls & shoots at the other players (shoots 3 bullets at each character & rolls in between aiming at the individual people in the match) Level 3: Vehicle chase scene (think of the missions Just Business & Reuniting The Families)
Minion: There's a few he could have such as CJ, Ryder, Tenpenny, or Sweet
Costumes: Normal Smoke http://images.wikia.com/gtawiki/images/4/41/BigSmoke-Artwork.jpg
