Angry Birds Epic Bottomless Cave Dungeon is unlocked after passing Lake Land level 3, which occurs during the pursuit of the submarine. Like all dungeons, this level is difficult but not the worst by any means. Focus on birds with high health while battling hog after hog. As usual, it’s a 5-wave battle. For help you can borrow on of your friends’ birds in addition to two of your own. Alternatively, you can use Piggy McCool as a default friend, or pay to use one of the Mighty Eagle’s more-elite birds.
