Another official expansion to the free-to-play card game Hearthstone: Heroes of Warcraft by Blizzard Entertainment. This time the developers send us to the unexplored forest of the Un’Goro crater, which is inhabited by intriguing, but also very dangerous species of fauna and flora. We follow the team of explorers led by Elise Starseeker, encountering mighty dinosaurs, wild elementals, carnivorous plants and many other interesting organisms. Add-on introduced 135 new cards, a new keyword (skill) called Adapt, and a new card type (Task), as well as a board with an Un’Goro crater theme and a card back fossil. Developers also implemented another group of minions, consisting of Elementals. It consists not only of magical creatures from this expansion, but also some older cards.
