You can unlock more moves in the game, as well, such as the ability to pass the ball out of bounds to a friend who can pass it back to you or do acrobatic stunt dunks where you climb up on an opponent before throwing it down on him. There's also a way to post up players, which involves a button-mashing minigame to fight for position when you back down your opponent. But for the most part, the most fun and effective way to play Rebound is to use a slick-handling guard who can pull off a lot of ankle-breaking moves and throw alley-oops to himself off the glass or the opponent's head. As far as defense goes, since there isn't really much in the way of collision detection in the game, position defense doesn't work out as well as going for lots of steals or blocked shots, which makes for entertaining, offensive-oriented basketball that occasionally offers a spectacular block or steal.
If you tire of the game's single-player modes, Rebound offers local Wi-Fi ad-hoc play for up to two players. There's no game-sharing mode, but you can take your unlocked ballers into the game and play on any cribs you've unlocked. The game works about as well as you'd expect in this mode, and you can tweak options, such as winning conditions, to your liking.
Overall, NBA Ballers: Rebound is a competent arcade basketball game for the PSP, retaining everything that was cool about the original game, such as the gameplay design and graphics, but also keeping a lot of the not-so-great aspects, such as long loading times and not enough unlocked content at the outset of the game. If you never played the original game or just want a good basketball game to play on the go, Rebound fits the bill. If you already played Ballers and were hoping for more refinement or something a little different, the game is pretty much the same one you played two years ago.
