Ragnarok is a free, official, non-canonical DLC expansion map for ARK Survival Evolved.

Ragnarok adds several new creatures, such as the Ice Wyvern, Iceworm Male, Dire Polar Bear, and Griffin, as well as 4 new dungeon bosses: the Spirit Dire Bear and Spirit Direwolf, the Iceworm Queen and the Lava Elemental. It’s a whole new map that boasts an expansive 144 sq. kilometer environment, an active volcano, species from Scorched Earth, and higher than average spawn rates of Megalania and Ovis (creatures that are harder to find on other maps). On Ragnarok there are unique Beaver Dams; they are bigger and look more like beaver dams in real life. Beavers can live in the dams, too.

Ragnarok is approximately 2.5x the size of The Island, in terms of land mass, and roughly 4x in total size. These calculations do not account for the significant, wide-ranging cave networks, and sizable dungeons.
