Frequently Asked Questions

What biome should I explore first?
Start with the Shallow Waters biome, which is the safe starting area with abundant basic resources like Titanium, Copper, and Quartz. This biome has gentle currents, friendly fauna, and no dangerous predators, making it perfect for early game survival and learning the basics. Once you have a Seamoth and reinforced equipment, progress to the Kelp Forest and Grassy Plateaus for mid-tier resources.
What depth do I need for deeper biomes?
Depth requirements scale with biome difficulty. Shallow Waters are 0-50m, Kelp Forest and Coral Gardens range 50-200m, Twilight Zone starts at 200m, Crystal Caverns begin at 400m, and the Lava Zone requires reaching 800m or deeper. To survive deeper biomes, you need a Reinforced Suit, a vehicle like the Seamoth or Prawn Suit, and upgraded oxygen capacity. Plan your dives carefully and always have an escape route.
Which biomes have the most resources?
The Kelp Forest and Grassy Plateaus are resource-rich mid-depth biomes offering Titanium, Copper, Sulfur, Silver, Gold, and Lead. Crystal Caverns yield diamonds and rare crystals, while the Lava Zone contains Kyanite and other rare endgame minerals. For early game, the Shallow Waters biome provides all the basic materials needed to craft your first tools and build a starter base.
Are there dangerous biomes to avoid early game?
Yes, avoid the Twilight Zone, Crystal Caverns, and Lava Zone early in your playthrough. These deep biomes are patrolled by Leviathan-class predators and require advanced equipment like the Reinforced Suit and Prawn Suit. Even mid-depth biomes like the Grassy Plateaus can be dangerous due to Sandsharks and other ambush predators. Always check the danger level on each biome entry before exploring.
Do biomes change with game updates?
As Subnautica 2 is in Early Access, biomes may change with updates. Developers may adjust biome boundaries, add new biomes, or introduce new resources and creatures. Our database is verified against the current EA build and is updated when new content is released. Check the version badge on this page for the latest verification date.
