Today, Angry Birds Seasons gets some love as Rovio issues a free summer update which brings thirty new underwater levels. Building upon the concept of gravity first introduced in Angry Birds Space, Rovio has now brought gravity-defying action to the Seasons. You can fling the birds underwater and, yes – pigs sink to the bottom of the ocean.
Angry Birds Seasons is now an aquatic wonderland. The summer update is free for existing owners of the game.
