Floating Island
Above-water landmass with abandoned bases, rare plants, and scannable fragments. Safe from aquatic predators. A unique land exploration biome.
Quick Facts
Overview
The Floating Island is a rare above-water landmass rising from the ocean surface, offering a completely different exploration experience from the underwater biomes that dominate Subnautica 2. Covered in lush vegetation, rocky outcrops, and the ruins of abandoned habitats built by previous inhabitants of this ocean world, the island is a safe haven where you can walk on solid ground, breathe unlimited air, and explore without the constant pressure of oxygen management and predator avoidance.
The island's primary value lies in its abandoned bases. These structures, left behind by a previous expedition, contain scannable fragments for advanced blueprints, databank terminals with story-related information, and supply caches with rare materials. The vegetation on the island includes unique edible plants not found underwater — the Lantern Tree, Bulbo Tree, and Marblemelon Plant — which can be harvested and cultivated in your own base for a renewable food and water source.
Visiting the Floating Island is a major milestone in any playthrough. The blueprints and databank entries found here unlock critical mid-game and end-game crafting options, including advanced base modules and vehicle upgrades. The island also serves as a safe staging point for deep-water exploration in the surrounding area, providing a place to resupply and plan without the pressure of underwater hazards.
Resources
The Floating Island's resources are primarily botanical and technological. The unique plants found here can be harvested and cultivated in your base for renewable food and water. The abandoned bases contain scannable fragments for advanced blueprints that cannot be found elsewhere.
Lantern Fruit
From the Lantern Tree. Edible fruit providing food and water. Can be cultivated in your base.
Bulbo Sample
From the Bulbo Tree. Edible sample providing water. Can be cultivated for renewable hydration.
Marblemelon
From the Marblemelon Plant. Provides both food and water. The most efficient renewable sustenance source.
Creatures
The Floating Island itself has no hostile creatures. The surrounding waters contain standard shallow-water fauna, but the island surface is completely safe. No predators patrol the land, making exploration here a relaxing change of pace from the dangers of the deep.
