Where to find Celestina in Subnautica 2

Celestine in Subnautica 2 is one of the most important minerals during deep-sea exploration, as it proves indispensable in advanced projects, equipment upgrades, and the construction of useful structures within the underwater base. Its distinctive bluish sheen makes it easy to locate. 

However, unlike basic materials scattered near the Lifepod, celestine appears in more dangerous and remote areas. Because of this, the player needs to explore less safe biomes, face hostile creatures, and dive to greater depths. Below, see where to find this material!

Where can I find Celestina in Subnautica 2?

Finding celestine in Subnautica 2 might seem tricky at first, especially since the ore doesn't appear near the starting area. Fortunately, there are much more efficient mining regions. The best spots are in deep areas near larger rock formations. Ideally, bring extra oxygen, a spare battery, and have your tools prepared before the trip. Below are the most efficient locations to obtain this resource.

Alien Ruins

The Alien Ruins are among the richest locations in celestine within the game. Many players consider this region the main mining point due to the enormous amount of deposits scattered throughout the environment.

To get there, follow this path:

• Go approximately 1300 meters east of the Lifepod;
• Keep moving forward until you find the alien structures;
• Descend approximately 250 meters;
• Look for rock walls with an intense blue sheen.

In this area, deposits appear much more frequently than in other biomes. Most of them are trapped in rocks, so the Sonic Resonator will be necessary for collection. In just a few minutes you can leave with an almost full inventory. Even so, be careful. Some aggressive creatures patrol the vicinity of the ruins, especially in the darker areas.

Submerged Plateau

The Plateau also has good reserves of celestine in Subnautica 2, although in smaller quantities compared to the Alien Ruins. Even so, many people prefer this biome because it offers a less dangerous route. The path tends to be more tranquil, especially on the first deep expeditions.

Here's how to find the location:

• Follow the path approximately 1000 meters east of the Lifepod;
• Go down approximately 200 meters;
• Explore the rock formations scattered across the ocean floor.

The deposits often appear clustered near underwater slopes. In some areas, the blue glow is very helpful for locating them, even in low-light conditions.

Which tool should I use for mining?

Many players find the ore but fail to collect anything because they forget the correct tool. Celestine deposits in Subnautica 2 are protected by resistant rock layers. Therefore, the Sonic Resonator ends up being indispensable during extraction.

After breaking open the mineral structure, one to three fragments typically emerge that are available for manual collection. It's also worth bringing extra batteries. Long mining sessions tend to consume a lot of energy, especially in deep areas.

What is Celestina used for?

Celestine is useful in several important campaign projects. Without this resource, some advanced upgrades are blocked. Check out the main uses of this ore.

Axum Wall Lamp

This item greatly assists in illuminating underwater bases. Dark environments can hinder organization, navigation, and even equipment identification. The manufacturing of the light fixture utilizes:

• 1 unit of Celestina;
• 1 Titanium Chip.

In addition to its functional use, many people use the item for interior decoration of the base.

Strontium Production

Strontium appears in more advanced recipes and is directly dependent on Celestine. In this case, the following are needed:

• 2 units of Celestina.

Because it is an important component in the later stages of the game, many players prefer to keep large stockpiles stored away.

Tadpole Mk.1 Depth Module

Among the most important items related to deep-sea exploration, the Girino module deserves special mention. It allows the vehicle to reach even deeper regions of the ocean, greatly expanding exploration possibilities.

The recipe uses:

• 3 units of Celestina;
• 1 System Chip;
• 2 Enameled Glass Bottles.

This ends up being one of the main reasons why so many players look for Celestina in Subnautica 2 right in the middle stages of the campaign.

Subnautica 2 is coming to PC and Xbox Series X|S.
