Subnautica: archived offer and access details

The Steam free weekend ended on April 6, 2026. It offered temporary play access, not a permanent free copy of Subnautica.

Check the licence, not the old headline

A free weekend ends when its trial period ends. A free-to-keep offer requires a valid claim during its promotion, while a free-to-play listing can have separate paid content. Those are different arrangements. Read the actual store’s current terms rather than inferring permanent ownership from an install button.

If you claimed it at the time

Check the library and licence history of the account and store you used. Access on one platform does not automatically supply a key for another. If you did not claim the historical offer, consult the current listing before making plans or paying. We have not redeemed a new offer or tested a paid purchase to update this notice.
