Subnautica
An underwater survival game on an ocean planet where the player manages oxygen, food, and water while crafting tools, submersibles, and bases to explore deeper and escape.
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.

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