Instructions
Start a game of "NBA 2K10" and wait for a moment when you break away towards the opposition basket with little interference from the other team.
Run towards the opposition's basket, controlling your player with the left analog stick.
Hold the R2 trigger button down to enter "turbo" mode as you approach the basket.
Rotate the right analog stick around 360 degrees counterclockwise. Your player will jump towards the basket and perform a 360-degree pirouette before dunking the ball home.
