The bubble-busting action-puzzle game makes its debut on Xbox in this release, which features online multiplayer support through the Xbox Live service. Connected gamers can go head-to-head, and even talk back and forth using the Xbox Communicator headset. As in earlier iterations, the object of the basic game is to remove bubbles from the top of the playing field by shooting bubbles of matching colors into the mix from below. Several modes of play are offered in this "Ultra" version of Bust-A-Move, including new game types such as "See-Saw Puzzle" and "Blind Puzzle."
