When Rovio announced Angry Birds Rio, the game publisher promised it would offer a new episodic update each month through November. Later this week, Rovio will begin to follow through on that promise when it introduces Angry Birds Rio: Beach Volleyball. The update will provide 30 new levels and more achievements. It will presumably launch across the multiple platforms on which Angry Birds Rio is available, including webOS, Android, and iOS. Hit the jump for a video preview of Beach Volleyball.
