Play Subnautica for Free on Steam as Sequel Nears Release

The beloved underwater survival game, Subnautica, is currently available for free on Steam for a limited time. This special promotion allows players to dive into its critically acclaimed alien ocean world as developers prepare for the highly anticipated release of its sequel.

Players crash-land on a mysterious oceanic planet where survival means venturing ever deeper into the unknown. Subnautica’s vast underwater environments range from sun-drenched coral reefs to treacherous deep-sea trenches, active lava fields, and bioluminescent subterranean rivers. Players must carefully manage their oxygen supply while exploring lush kelp forests, expansive plateaus, intricate reef systems, and winding cave networks. The waters teem with diverse marine life; some creatures are beneficial, while many pose significant dangers.

This free access period for Subnautica on Steam will run until April 6th.

Looking ahead, Subnautica 2 is slated for an Early Access release later this year, promising new adventures and challenges in the franchise’s evolving universe.
