I cant find my DLC

Try going to your Apps & Games, press start on the game then Manage game and extensions. Once you're there, you should see everything you bought even if its not in game.

As you stated this game is old. You might need to contact the maker to see what can be done. YOu already have all the other DLC which is great. I know sometimes free DLC is only available for a limited time. YOu also need to check the DLC where you scratched
off for code and read all around and make sure its no small print anywhere. I would call them up though to further assist.

Hello Pablo,

Thanks for reaching out to the forums. We understand you have question on DLC character. Have you played the game at all? Some DLC doesn't become available until you reach a certain point in the game. Since you have the majority of the DLC, we recommend
posting to the evolve forums or
2K Games.

Thanks,

Brad

Are you 100% sure you are using the same account?

Is the DLC appearing here?

Is the DLC appearing when you go to manage your add ons?

In My games & apps, highlight a game (but don’t select it).

Press the Menu button  on your controller, and then select Manage game and add-ons.

Hi there thanks for replying, it’s not in either of the places you mentioned
