A new official roster containing lineups updated through December 21st 2012 has been pushed through for the PC, Xbox 360, PlayStation 3 and Wii U versions of NBA 2K13. The rosters will come through automatically as long as your computer or console is connected to the Internet, though PC users may also choose to update their game manually using this pack, which contains the latest rosters and online data files.
The latest update also includes the Kobe 8 ID shoes, which carry a +5 Strength boost. Kobe is wearing the shoes by default in the new rosters and they can also be accessed via the NIKEiD menu.
