Subnautica + Below Zero Bundle — Steam Offline Activation

Subnautica and Subnautica: Below Zero, offline on your own PC.

Unknown Worlds' first game starts with a crash: your ship goes down over an alien ocean and you climb out of a lifepod with a fabricator and little else. You scavenge the shallows, build habitats on the seabed and push into deeper, darker water in the Seamoth, the Cyclops submarine and the Prawn suit, piecing together what happened to the planet while leviathans patrol the deep.

The bundle adds Below Zero, set in the planet's arctic region, where Robin searches for the truth about her sister's death and crosses snowfields on a Snowfox hoverbike and open water in a modular Seatruck.

You can play Subnautica offline from start to finish in both games — each is single-player only, so Offline Mode takes nothing away.

We send the account details in the chat and you play in Steam's Offline Mode. No expiry, no time limit.
