To call Angry Birds a success would be an understatement, just take a look at all the formats the game has been released for to the right. Now we can add Facebook to that list, which Rovio plans to unleash the angry birds on in the near future. Rumour has it that this version will come with some form of social co-op play and that the evil green pigs will play a larger role this time around. Have a look at the game's Facebook-page for more information.
