Though the "Angry Birds" are certainly getting a fair amount of attention with their upcoming "Go!" kart racing game, Rovio hasn't forgotten about the spinoff "Bad Piggies" franchise. The developer has released a new Halloween update for the game, which is available free of charge and should prompt automatically the next time it's updated.
In "Tusk Till Dawn," players will take on a set of new levels and challenges as they attempt to cross a finish line with a number of makeshift vehicles they put together using select parts. The update also features various Halloween-themed skins for the "Piggies" characters, ranging from a Jason Voorhees-like psycho masked Piggie to a vampire Piggie. They change at random, so cycle through all the parts available and see how many pigs pop up.
You can download "Bad Piggies" (which includes the Halloween levels) for iOS and Android.
