MyNBA2K for iOS, Android, and Kindle Fire devices is a free companion app that lets you “warm up” before the big game on your console with a variety of minigames and rewards. NBA 2K: MyLIFE is a social game on Facebook that also sends bonuses back to your NBA 2K13 career as you manage your player’s life off the court.
Both of them will be available soon with MyLIFE debuting next Tuesday, October 9, while MyNBA2K comes out this Friday, October 5. Here’s a look at what you can expect when both apps are live.
