The Dunes is a biome located west from Lifepod 5, on the edge of the map, bordering one of the Grassy PlateausSea Treader's Path, one of the Safe Shallows, both of the Blood Kelp Zones, the Northwestern Mushroom Forest and the Crater Edge.

There are three Wrecks within the Dunes. One can be found near the Northwestern Mushroom Forest, having seemingly slid down the sandy dunes from the forest. Another two, smaller wrecks are also found in the Dunes near the Sea Treader's Path border.

A large sinkhole can be found approximately 220m south from Wreck 6 (The one closest to the Northwestern Mushroom Forest.) The Dunes Caves are found within along with a Cuddlefish egg, located right in the center of the sinkhole.

This biome also harbours a large crater from a meteor impact, which can be found close to the border with the Northern Blood Kelp Zone.

Spoiler alert: The following section contains story related material.

Sanctuary Cache can be found within the meteor crater.

An Alien Vent Entrance Point is found in the Dunes.

One of the five Sea Emperor Juveniles can be found here after the Sea Emperor Leviathan Eggs have been hatched.


The Dunes feature vast, sandy plains and dunes, sometimes littered with various types of rock structures. It is also home to many dangerous types of Fauna, the most notable one being the eight Reaper Leviathans that patrol the open spaces of the biome. These leviathans and the PDA summary of the biome heavily discourage players from entering the biome.

Gasopods can be found, alongside their eggs, near the several hydrothermal vents in this biome. Most of the Flora and Coral is also located near these, alongside Lithium and Rubies. Reaper Leviathans often wander close to the hydrothermal vents so tread carefully.

Four Sea Crowns are located within the sinkhole of this biome. It is recommended to approach the sinkhole with caution, as there is a Reaper Leviathan that is always close to it.

Even in the daytime, the Dunes are quite dark and murky, making it difficult to see threats. It is recommended to keep track of where the Reaper Leviathans reside and give those areas a wide berth.

If building a base in the Dunes, a Scanner Room is incredibly useful. Not only can it be used to scan for resources, but it can also be used to keep track of the Reaper Leviathans in the vicinity. This is especially effective with a Scanner Room HUD Chip.
