Game Modes

Subnautica features four different Game Modes. The player can select a Game Mode when starting a new save file; a save file's Game Mode cannot be changed after creation. Each Game Mode imposes different restrictions (or lack thereof) on gameplay.

Freedom Mode
To stay alive, the player must manage their health and oxygen levels. If the player runs out of either, they die and lose all of the items in their inventory. The player can return to where they died to attempt to reclaim their lost items. 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 in 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 will begin to lose health until 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
This is a sandbox mode for players who want to freely explore and build. The player cannot die and does not have to worry about health, oxygen, hunger or thirst. Materials and Blueprints are not required for crafting, and vehicles and Seabases do not require Energy to operate and cannot be damaged. However, the player cannot make any story progress in this mode.
