A second expansion pack for Ark: Survival Evolved has launched on PC, PlayStation 4 and Xbox One. It's called Aberration and it is, as the title suggests, unusual.
Aberration is the name of a malfunctioning Ark with an underground biome. There's radioactive sunlight, earthquakes, ziplines, wingsuits, climbing gear and weird creatures. There are spooky humanoids called Nameless, and Reapers who impregnate enemies to spawn offspring. Apparently if you let the Reaper Queen impregnate you, you spawn a Reaper you can tame and control.
It won't be the only new beast you can tame. You can climb and fly on the back of a camouflaged Rock Drake chamaeleon thing; you can stamp around with a giant Cave Crustacean, which is probably an overgrown crab; and you can light the way with a Lantern Pet.
To survive underground you will need to craft a whole array of new equipment, ranging from rock picks to hazmat outfits, railguns (!!), glowsticks (!), and more. There are fishing baskets, gas collectors and cliff structures for building bases.
Ark: Aberration costs $20 standalone or comes free as part of the game's Ł35 Season Pass.
