Just a few hours after being released, Bad Piggies, the long-awaited follow-up to Angry Birds, is topping the app charts for both iOS and Android, reports CNET. In Bad Piggies, you change teams, manipulating the pigs instead of birds—players use umbrellas, wings, propellers, and other tools to find pieces of a map that will reveal the location of some primo bird eggs. iPhone and iPod versions of the game cost 99 cents, while the iPad's goes for $2.99; the Android version is free on Google Play because of a promotional tie-in with game-maker Rovio.
