parts

9 mechanics, as Subnautica does them

core · 2

resources & production

Hand crafting

Gathered resources are crafted into tools, base parts, and submersibles from blueprints the player has recovered.

biology & health

Survival meters

Health, hunger, thirst, and oxygen deplete in Survival mode; oxygen limits each dive's depth and duration, Freedom mode removes hunger and thirst, and Creative removes all depleting stats.

supporting · 7

space & construction

Building placement

Bases are assembled from placed modules.

environment & ecology

Day-night cycle

A day-night cycle and frequent eclipses change visibility.

control & automation

Direct avatar control

multiplayer & persistence

Modding API

No official API; mods load through de facto loaders such as BepInEx.

risk & failure

Permadeath

Optional in Hardcore mode.

resources & production

Power grid

Bases and vehicles need energy sources.

resources & production

Spoilage

Cooked fish spoils over time; cured fish does not.

core loop

dive from the lifepod -> gather resources and recover blueprints -> craft tools, vehicles, and base modules -> manage oxygen, food, and water -> dive deeper into new biomes and story sites -> build the means to escape the planet

design notes

Included as a boundary case: the map, story, and progression are hand-authored, and the simulated layer is a set of survival meters plus base power and fauna behavior. Oxygen is the distinctive meter because it ties survival to depth and distance from air, making range a resource. Mode settings remove meters to change genre: Freedom drops hunger and thirst, Creative drops all depleting stats, and Hardcore adds permanent death without low-oxygen warnings.
