Subnautica (2025) — Free Download for Mac

Subnautica is an underwater adventure game set on an alien ocean planet. Explore a vast open world full of wonders and dangers!

Dive into the vast underwater world

You've been shipwrecked in a wondrous ocean world where the only way out is down. Subnautica's oceans range from sun-drenched coral reefs to treacherous deep-sea fissures, lava fields, and bioluminescent underwater rivers. Manage your oxygen levels as you explore kelp forests, plateaus, reefs, and twisting cave systems. The waters teem with life, some beneficial, many dangerous.

Collect, create and survive

After crash-landing in an escape pod, it's a race against time to find water, food, and craft survival gear. Scavenge resources from the ocean around you. Craft knives, diving gear, and personal watercraft. Venture deeper and further to find rarer resources that will allow you to craft more advanced items.

Build underwater dwellings

Build bases on the seabed. Choose the layout and elements, control the durability as the depth and pressure increase. Use the base to store resources, dock transport, and replenish oxygen supplies as you explore the vast ocean.

Solve the mystery

What happened to this planet? There are plenty of signs that something is wrong. What caused you to crash? What is infecting the sea life? Who built the mysterious structures scattered across the ocean? Can you find a way to get off the planet alive?

Break the food chain

The ocean is teeming with life: use the ecosystem to your advantage. Lure and distract dangerous creatures with fresh fish, or simply swim as fast as you can to avoid the jaws of wandering predators.

Overcome the pressure

Build a Jet Autonomous Armored Suit (or "CRAB") and explore extreme depth and heat. Modify your suit with drills, torpedo launchers, propulsion cannons, grappling hooks, and more.

Beware of the night

When the sun goes down, predators emerge. The ocean is unforgiving to those caught unawares in the dark. Places that are safe to explore during the day become treacherous at night, but also reveal beauty that those who avoid the dark will never see.

Dive below the seabed

Below the seafloor, cave systems branch out, from dark, cramped passages to large caverns illuminated by bioluminescent life and scorching lava flows. Explore the world beneath the ocean floor, but keep an eye on oxygen levels and beware of threats lurking in the darkness.
