Angry Birds are among the top most games that have taken Android, iOS, Windows phone, Windows, Xbox and what not by storm. We can simply calculate its likeliness among users by looking at the records this game made last year. Finally, after hitting the poor pigs from the past three years, Rovio has decided to give you the hold over pigs rather than birds this time. This new game is called the “Bad Piggies” and encloses the pig side story where you can play with them without using the slingshots. The game will be out on 27th of September and it will be first available for the Android, iOS and OS X, while the Windows phone, Windows 8 and PC will get it later.
