If you've gotten the NBA 2K24 Black Mamba or 25th Anniversary edition once, a second time can only get better, right? We’d like to thank you for your creativity and aspirations to the Mamba Mentality, but we want you all to know that when you do this, the extra VC, items, and MyTEAM packs you get in the game are not able to be added again.
This is because once you’ve already put in the code from your first purchase, the DLC for that version has already been added and both the system and game mark your account as having it. So when you add another code from an additional purchase, nothing shows up because the game recognizes your account as already owning everything.
