Bad Piggies, a new game based in the same universe as the Angry Birds, will be released September 27 for iOS, Android and Mac, Rovio has announced.

The new game promises to turn the multi-million selling franchise on its head by letting fans play as the pigs. We're told to expect all new gameplay and not a slingshot in sight.

"There's a lot of empathy towards the lovable enemies from the Angry Birds games, and we've been constantly asked: what about the pigs' side of the story?" said Mikael Hed, CEO of Rovio. "Bad Piggies gives you the chance to play as the second-most-loved characters in the Angry Birds universe, and explore this rich world through their green eyes."

Versions for Windows Phone, Windows 8 and PC will follow shortly after.
