My boyfriend bought Red Dead Redemption 2 Special Edition for Xbox One. He has misplaced the disc and can't find it anywhere. If he buys a copy that doesn't have the add ons, will he be able to play the add ons? Were they installed with the base game? He is still playing the main story and hasn't accessed the add ons yet. If he's able to play the add ons, if they're already installed, he won't feel so bad if he has to buy the base game.
