The Center is an official non-canonical (free DLC) expansion map that has a default difficulty level of 5.0 which means wild dinos up to level 150 and better loot quality from supply drops. Prior to January 2017, Giganotosaurus had an extremely rare chance to spawn anywhere on the map; now Giganotosaurus will only spawn in a few areas such as the Lava Biome and Northern Snowy Mountain. The center is based on the novel Journey to the Center of the Earth and the story is your journey to the center of the earth. It originated as a custom map by modder Ben “EvilMrFrank” Burkart. It was added to ARK: Survival Evolved as free DLC in PC patch 241.0 and Xbox One update 734.0. It underwent a "mega-update" that added the Redwood Forests in PC patch 245.0 and was released on Xbox One and PS4.
