Bad Piggies, the Angry Birds spin-off from Rovio, shot to the top spot on the US iTunes App Store within three hours of launch. The firm said the game was the fastest chart-topper in the company’s history. The game is the third from the Finnish studio this year to nab the top spot within it’s first day of release. These titles were Amazing Alex and Angry Birds Space. Rovio plans to add new levels and story content via free updates, and the first one will arrive “in the next few weeks.” Thanks, GI International.
