Wow, Rovio’s next game is not an Angry Birds game – though, of course, it does take place within the deep Angry Birds Universe. Bad Piggies stars the hated pig spheres from Angry Birds, and features “all new, never-before-seen gameplay – and not a slingshot in sight!” The teaser video doesn’t show exactly what the new gameplay is, but we’ll find out by September 27 at the latest, when Bad Piggies launches on iOS, Android, and Mac. Other versions coming afterward include Windows Phone, Windows 8 and PC. Read the full story at Joystiq.
