On Monday, Twitter users started to report unskippable ads in NBA 2K21. You can see such ads during loading screens in every game mode.
You can ignore 2KTV ads, a show from developers about different in-game features. However, you can not skip sponsored videos. For example, an Oculus Quest 2 ad appears inside the PS4, Xbox One and Windows PC versions of the game and cannot be skipped even if the loading is over.
It is not yet known if such ads will appear in the PlayStation 5 and Xbox Series versions of NBA 2K21, which will cost $10 more.
