A nature documentary-style deep dive into the oceans of Subnautica. Explore the seas of planet 4546B, and discover the biology of these alien lifeforms. The vast oceans of the popular video game Subnautica teem with alien creatures--some friendly — and some deadly. While the game focuses on survival, the lifeforms of Subnautica are amazing even when they’re trying to eat you: possessing fascinating biology, bizarre behavioral patterns, and hidden mysteries. For this entry into the archive, we’ll embark on a nature documentary-style expedition, touring Subnautica from the shallows to the abyssal trenches; swimming in the shadows of giants, and evading reaper leviathans. This series will reveal the biology behind these puzzling lifeforms, and investigate how they differ from life in our own oceans.
