Shock Drop codes

Is there any way to get Xbox codes for the shock drop/Dahl training arena? My nephew bought the game and wants to play that area but doesn’t have the code for it. So was just wondering if its at all possible to get theses codes without having to buy the game.

The Shock Drop area can always be purchased from the DLC menu. You do not have to purchase the game for it.

it actually came with the game if it was pre-ordered, but was made available for purchase just shortly after the game released, so other then purchasing it (the DLC for it) , No other way available

Thanks. That was the answer to my question. I appreciate it.
