Game Modes

Subnautica currently features four different Game Modes.

Freedom Mode

To stay alive, the player must manage their Oxygen and Health levels. If the player runs out of either, they die and lose all of the items in their inventory. The player can "secure" their inventory by entering Lifepod 5, a Seabase, or a Cyclops; if the player dies with a secured inventory, they will keep all the items from the last time their inventory was secured and will respawn at the last place they secured their inventory.

Survival Mode

Similar to Freedom Mode, but the player must also maintain Food & Water levels in addition to Health and Oxygen. If the player runs out of either Food or Water, they die.

Hardcore Mode

Similar to Survival Mode, but restricts the player to a single life only; if they die, the game ends, forcing them to completely start over from the beginning. In addition to this, the PDA will not warn the player when they have low levels of oxygen.

Creative Mode

In Creative Mode, story, health, oxygen, hunger, and thirst are disabled, materials and Blueprints are not required for crafting, and vehicles and Seabases do not require Energy to operate and cannot be damaged. This is a sandbox mode for players who want to freely explore and build.
