We’re excited to announce that Subnautica 2 Experimental is now available through the XBOX Insider Program, giving players the opportunity to experience upcoming updates early and help shape the future of the game alongside the team at Unknown Worlds.
Explore Tomorrow’s Updates Today
The Experimental preview gives you access to in-development content before it’s released to all players. These builds allow the development team to gather valuable feedback, identify issues, and refine upcoming features with the help of the community.
Because these are pre-release builds, you’ll encounter bugs, unfinished features, balance changes, and other rough edges along the way. That’s all part of the adventure. Every issue you report and every piece of feedback you share helps improve future updates and create a better experience for the entire community.
Before You Dive In
Here are a few important things to know before joining Experimental:
- You’ll need to own Subnautica 2 or have access through an active Game Pass subscription.
- Experimental builds contain content still under development and may be less stable than the regular version.
- Experimental players can only play multiplayer with other Experimental players.
- Saves are version-specific. Experimental saves cannot be used in the Stable version, and Stable saves cannot be used in Experimental.
Your save data isn’t deleted. Experimental and Stable saves are kept separate, and each version can only access its own saves.
