Hot on the heels of the gravity-defying mobile game 'Angry Birds Space' comes a new update to 'Angry Birds Seasons' that promises 30 all-new levels of pig-pounding action. Want to guess how we'll be spending our summer?

Called 'Piglantis,' the new levels introduce underwater physics and an entirely new soundtrack. Players will be able to make their birds dive into the ocean and perform nifty submarine attacks on those egg-stealing pigs.

The update is available for both iPhone and Android devices. Get smashing now! Those stolen eggs won't save themselves. Check out several images below.
