If you’re trying to fix the Power Plant <\/strong>in Subnautica 2<\/u><\/a>, you’ve likely realised that you need to power up the area in order to access the Observatory<\/strong>\u2014that big tower near the Alien Ruins<\/u><\/a>. This is your big story objective in early access, and actually concludes the narrative so far when you do get inside, teasing some future content and updates.<\/p>\n

Actually repairing the Power Plant is very resource-intensive, and requires many of the upgrades you’ll find in the region, making it the culmination of your journey through the alien ocean so far.<\/p>\n

How to repair the Power Plant in Subnautica 2<\/span><\/h2>\n

To enter the Observatory, you first have to repair the Alien Power Plant, the huge structure above the Angel Comb that dominates the Alien Ruins region. There are multiple stages to this, so I’ll walk you through each, though it’s worth noting that you’ll need the <\/strong>Tadpole<\/strong><\/u><\/a> Depth module<\/strong> to do any of this.<\/p>\n

1. Clear the Angel Comb and get Axum Vision<\/h3>\n

Your first step is to clear the Angel Comb<\/u><\/a> in the Alien Ruins, the center of which is to the east of Research Base, if you follow the big purple tube. All of the details you need are in that linked guide, including videos showing each of the viral bloom locations. To destroy each of these, you’ll need to unlock the <\/strong>Feedback Resonator<\/strong><\/u><\/a> upgrade for your Sonic Resonator, as this allows you to destroy the flowers from a distance so they don’t close up. <\/p>\n

After you’ve cleared the comb, acquire the Axum Vision Adaptation, then head inside the alien control room<\/strong> built into the wall of the crater, overlooking the Angel Comb. Interact with the console at the centre by the window to fix the first stage of the Power Plant.<\/p>\n

2. Repair the Alien Turbine and restart the Power Plant<\/h3>\n

Your next step is to repair the giant Alien Turbine above the Angel Comb. Drive directly upwards onto the big circular structure and move around to the east side of its circumference, where you’ll find a few colony crates and a blue light, above a broken turbine you can scan. If you’re unable to scan this, it’s possible you might need to craft the <\/strong>Bioscanner<\/strong><\/a> upgrade<\/strong> first, though I can’t confirm this for sure since I already had it when I scanned the turbine.<\/p>\n

Scanning the turbine reveals it was sabotaged (presumably by the colonists) and you’ll need a lot of materials to repair it, namely:<\/p>\n
