Subnautica: Below Zero will be released on mobile devices on March 10.

Unknown Worlds Entertainment has announced the release of the underwater adventure game Subnautica: Below Zero on iOS and Android. The mobile version is scheduled for release on March 10, 2026, giving players the opportunity to explore the arctic depths of an alien ocean in a portable format. The project is an adaptation of the original game, previously released on PC and consoles, preserving key gameplay elements and storyline.

To optimize for mobile platforms, the developers have made a number of technical and interface improvements, including a redesigned touch control system, while maintaining support for external controllers for users who prefer traditional input methods. The save system uses a combined approach: data is stored locally on the device and automatically syncs via cloud services, allowing players to continue playing across devices without the need to manually transfer files.

Russian language support for the interface and subtitles has been confirmed, ensuring the title is accessible to Russian-speaking audiences.
