Instructions
Gain control of the ball and dribble toward your basket. For best results, give the ball to a point guard or player with a high passing rating. This ensures that an accurate pass will be thrown and increases the chances of a successful alley-oop.
Wait for a teammate to run toward the basket. If you're playing a multiplayer game, have your partner move a player toward the hoop. If you want to ensure that a dunk occurs, choose a taller player or a player with good jumping ability to be on the receiving end. A short guard not known for dunking will not be able to execute the play.
Press "L1" and "Circle" at the same time when the receiving player is in good position. "L1" is the button closest to you on top of the controller on the left-hand side. "Circle" is the default lead pass button in NBA 2K10 and is located on the right side of the controller. On a successful alley-oop, the receiving player will catch the pass while in midair and complete the play with a slam dunk.
