Beasts rage and battle across the screen, including classic monsters like King Gorilla, Lizard God and more! Tap your beast to send it into battle or drag it onto another to combine them into a new, unique monster. Collect monsters and their lost articles to upgrade your beasts and defeat stronger foes.
