The full underwater survival adventure on Android, with the mod menu, all three game modes and unlimited oxygen unlocked from the 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. From there the whole game is about staying alive underwater: scanning fish and coral for resources, crafting tools and oxygen tanks, building habitats on the seabed, and slowly piecing together what happened to the planet and the people who came 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 the pressure taken off. Oxygen does not tick down to a panic, resources do not run dry mid-build, and the menu lets you toggle helpers on or off whenever a dive gets tense.
That matters most for two kinds of players. People on slower or budget phones who want a stable, paid-for-free build without chasing in-app unlocks, and explorers who would rather sightsee the Aurora wreck and the deeper biomes than grind survival meters. The mod menu serves both without forcing a single play style.
