Newsbrief: Angry Birds developer Rovio isn't done with the behemoth franchise just yet. Today the company announced a sequel to the original game that looks to focus on the story from the perspective of the pigs. Bad Piggies is set to launch on September 27 for iOS, Android and Mac, with editions for Windows Phone, Windows 8 and PC to follow shortly afterwards. The game will give players the chance to take control of the enemies from the original series. Rovio has seen great success with its Angry Birds franchise, racking up more than one billion downloads across all versions, and hence is no doubt keen to capitalize on that popularity with this follow-up.
