The full underwater survival adventure on Android. The mod menu, all three game modes, and unlimited oxygen are unlocked from your very first dive.
Why this mod matters
Subnautica is an open-world survival game from Unknown Worlds Entertainment. You wake up in a lifepod after your ship, the Aurora, breaks apart over an alien ocean planet. Everything after that comes down to staying alive underwater. You scan fish and coral for resources, craft tools and oxygen tanks, build habitats on the seabed, and slowly work out what happened to the planet and the people who were here before you.
There is no official release of Subnautica on the Play Store. The Android build is a community port, and the mod APK on this page bundles the mod menu so you can start with some of the pressure lifted. Oxygen never drains into a panic, resources do not run dry halfway through a build, and the menu lets you flip the helpers on or off whenever a dive gets tense.
This helps two kinds of players the most. There are people on slower or budget phones who want a stable, paid-for-free build without hunting down in-app unlocks. Then there are explorers who would rather drift around the Aurora wreck and the deeper biomes than grind survival meters. The mod menu works for both, and it never locks you into one play style.

What this mod offers
- Full mod menu
An in-game toggle panel for the survival helpers. Switch them on for a relaxed dive or off when you want a real challenge.
- Unlimited oxygen
Stay under as long as you like. Deep biomes and the Aurora interior open up without that constant trip back to the surface for air.
- All three game modes
Survival, Freedom and Creative are all unlocked. Take limited resources and threats, simplified life support, or build with no limits at all.
- No resource depletion
Crafting materials and energy hold steady, so base building and vehicle upgrades never stall on one missing ingredient.
- Full content, no purchases
The paid game unlocks for free, with every biome, blueprint and story beat available. Nothing is gated behind in-app purchases.
- Touch controls and gamepad support
The port maps movement, scanning and building onto a touchscreen, and it pairs with a Bluetooth controller if you want a console-style feel.
