Angry Birds Rio is the surprisingly good game tie-in to the animated movie "Rio." While many co-branded marketing vehicles show signs of slipshod shoehorning, Angry Birds Rio expands on the core Angry Birds mechanic while adding some twists and improvements we hope will, ahem, migrate their way into the main game.
Fans of the titanically popular Angry Birds series will find the same basic interface and gameplay--but instead of crushing pigs, your avian assault team is freeing other birds imprisoned by smugglers, taking out menacing monkeys, and presumably doing other things as more chapters are added. (The game has several planned episodic updates through 2011.) Improving on the original, Angry Birds Rio adds some new environmental objects to interact with (or avoid), more visual depth (with a trick called parallax scrolling), and a boss fight with the movie's two starring macaws (whom fans of the movie may remember were voiced by Anne Hathaway and Jesse Eisenberg).
If you're a fan of Angry Birds, "Rio," or both, you can't go wrong with Angry Birds Rio. The price tag isn't particularly cheap, but with the additional episodic content, it's still a decent value.
