Darkness Descends with Cursed Predators

Wild Terra has descended into darkness where creatures offer an even more frightening presence in the game. Predators have been cursed and turned into zombie animals. Players who kill these infested Unholy Monsters can collect green brains that can be exchanged for ghoulish treats including a witch's hat, pumpkin helmet and unholy pets. 

You can check out all of the spooky details on the Wild Terra site.
