Bountiful bubble-busting begins anew in this sequel to 1998's Bust-A-Move 2: Arcade Edition on Nintendo 64. New features include four-player support for simultaneous competition, an edit mode that lets you create up to 25 puzzles to stump your friends, and eight selectable "characters" with individual attack ratings. As in the original, the object of the game is to clear a screen filled with bubbles before the ceiling collapses.<br><br>Bust-A-Move '99 features six different game types: Arcade, Multiplayer, Challenge, Win Contest, Collection, and Edit Mode. "Arcade" has you choosing one of three difficulty levels, a character, and whether you are competing against yourself, the computer, or a friend. The object is to advance through a specific number of rounds until the game is complete.<br><br>"Multiplayer" has you competing against up to three players (computer or human) as you play for points or wins. "Challenge" is a series of five rounds with five stages apiece, in which you'll be graded on both your performance and technique. "Win Contest" tests how many victories you can achieve in a row, while "Collection" offers a selection of 1,020 puzzles. Finally, "Edit Mode" gives you a chance to see how creative you are in designing your own puzzles.
