The new ARK expansion goes underground in a literal sense.

Studio Wildcard made an appearance at PAX West to announce an all-new expansion pack. Hot on the heels of the release of ARK: Survival Evolved, Studio Wildcard announced Aberration, a new expansion pack that will take place in underground caves and feature new creatures, items, and more powerful bosses to defeat.

Aberration has been destroyed, and players must build and survive on the new planet, which is mostly made of crystals and mushrooms in an underground setting. Some new creatures include the Lantern Pug, a dog/anglerfish combination; the Rock Drake, which can go into stealth, fly, and climb; the Cave Crustacean, which is capable of grabbing and throwing creatures, and the Nameless Queen, who impregnates foes to destroy them from within.

The Nameless are considered the dominant race in Aberration. Infused with elements, they are some of the most powerful creatures you will face in the game and the deeper you go down. Players can now equip climbing packs, ziplines, glowsticks, wingsuits, rail guns, hazmat outfits, and more.

Aberration will be released for $19.99 and also be a part of ARK‘s Explorer’s Edition Season Pass. Those who purchase the Season Pass will get cosmetic Aberration items such as a sword and helmet. The Aberration expansion pack will be available in October 2017.
