Subnautica is an explorer's dream.
In the distant future, you're seemingly the sole survivor of a disastrous crash landing on a vibrant ocean planet. Stranded with little more than a lifepod and a rather magical fabricator that can turn resources plucked from the ecosystem into sophisticated equipment, it's up to you to figure out what happened to your ship, the crew, and how to get back to a home that's far, far away.
Unknown Worlds has fully launched Subnautica following a long but successful stint on Steam Early Access. The wait was worth it. This might be the best underwater game ever made.
