Battle Defence is one of the best Zuma games around, offering hours of fun with its colorful and exciting gameplay. Just aim and shoot your bubble-creatures into rolling marble line. Once you match 3 or more of the same color, the bubbles will be eliminated. The aim of the game is to stop each wave of bubbles from reaching the cave. You can pop the bubbles carrying little signs in order to gain powerups like fast shooting, pausing the line, and using bombs.
