Rovio have released a nice new update for Angry Birds Seasons that’s perfect for the summer months. The summer update takes us to the underwater world of Piglantis, an obvious play on Atlantis and the dastardly pigs who’ve set this whole war off by stealing eggs. The update adds 30 levels of new gameplay dynamics as flinging birds isn’t quite the same underwater as it is on land. As usual, this update is free so go ahead and find it in the Google Play Store.
