Rovio launching Angry Birds Friends on iOS and Android

You might have not realized it, but Angry Birds exists on Facebook. Of course, you were probably too busy pecking away at the game on your iPhone or Android device. In any case, Rovio announced today that they will be launching Angry Birds Friends on iOS and Android, and you'll be able to challenge your Facebook friends right from your smartphone.

So far, Angry Birds Friends has racked up 60 million installs and around 15 million monthly active users. The game is pretty much the same as the mobile version, only there's a social aspect involved, where you can challenge your friends. Details are rather scarce at this point, but Rovio says that Facebook integration will be the main talking point in the new game.

Rovio says that the game will be available on both phones and tablets, and players will be able to "challenge their Facebook friends in weekly tournaments for the coveted bronze, silver and gold crown on the levels." Players will also be able to "gather daily rewards, send and receive gifts of power-ups with your friends and brag about your accomplishments."

Today's announcement comes hot on the heels of Rovio's financial earnings report yesterday, where the company posted a revenue of $200 million for 2012, which is over twice the revenue that Rovio brought in during the previous year. They also profited $71 million for 2012, compared to $45 million in 2011.
