In NBA 2K15's MyCAREER mode, you will become an undrafted free agent. It starts in January instead of before the NBA season, where you will be signing on with short-term deals trying to make a team in the NBA. Also, you'll have the option to scan your face into the game, so your player will look a lot more like yourself.
The big thing is that you'll be testing free agency at the very beginning, and testing different offers against one another. This is a unique take to the Career mode story, and it seems like a hopeful prospect that you'll be doing a lot of new things in this year's mode you haven't yet done.
What did you think about the opening scene and the face scan technology?
