After initially teasing the latest offering in the extremely popular franchise via its social media accounts, Rovio has now officially launched Angry Birds 2 for the iOS and Android platforms. Mobile owners may have seen a number of Angry Birds incarnations over the years, such as the Star Wars spin-off and the Transformers collaboration, but Angry Birds 2 is the official sequel to the biggest mobile game of all time, and promises to be "bigger, badder and birdier".
