Subnautica Teaser Trailer - Subnautica

This 2018 main game blends Adventure and Survival, tasking you with managing oxygen, food, and water after crash-landing on an alien ocean world. The core loop involves descending through diverse biomes—from shallow reefs to deep trenches—to gather resources, craft essential gear like submersibles, and build habitats. Its unique feature is the fully submerged, three-dimensional exploration set against a backdrop of both wonder and significant underwater peril.
