Angry Birds Rio, the latest free game in the Angry Birds franchise from Rovio, is now available from the Android Market. The game features two episodes — a total of 60 different levels – complete with some gameplay twists built around Rio the movie. Rovio has added new achievements, as well as “hidden fruits” that you’ll discover as you play. Instead of attacking pigs, as usual, your goal is to liberate imprisoned birds by knocking them out of their respective cages. We played through the first few levels of episode 1 and are digging it so far; it has the same addictive gameplay we’ve come to expect from Angry Birds. The best part? Rovio will add episodic updates each month through November. Hit the jump for a gameplay trailer.
