How To Activate The Alien Door And Alien Turbine In Subnautica 2

"The alien observatory door in Subnautica 2 is fairly close to the Alien Ruins biome/marker, which is a key objective once you're done with the Tadpole Pens. If you're just free-roaming, then the structure is actually 1,100 meters east of the Lifepod. Beware, though, because there are several enemies, including a deadly leviathan, along the way."

"Upon reaching the alien observatory, you'll notice a pedestal and a doorway. You can't do anything yet, as you're told that the device requires a massive amount of power to function. For now, though, just explore the Alien Ruins biome and the abandoned base. You should also craft the Bioscanner upgrade and Feedback Resonator upgrade. Both of these are integral for the next tasks."

Here's a quick summary: If you swim to the large open area past the base, you'll see a turbine directly above an Angel Comb. The Angel Comb itself will have a marker on your screen."

The alien observatory door is located near the Alien Ruins objective and about 1,100 meters east of the Lifepod, with enemies and a deadly leviathan along the route.

Exploration of the Alien Ruins biome and an abandoned base is recommended, along with crafting the Bioscanner upgrade and Feedback Resonator upgrade. Activation requires learning an ancient language through an Adaptation ability. A turbine sits near an Angel Comb marked on-screen, and two control rooms on cliffs contain terminals the character cannot understand. Following purple tendrils from the Angel Comb leads to destroying Bloom Cankers, which close when approached, but can be blasted using the Feedback Resonator.
