As anticipation builds for Subnautica 2, developer Unknown Worlds has made waves with the surprise announcement that the original underwater survival masterpiece will be making its mobile debut on July 8, 2025. The seven-year-old title, already available on PC, consoles, and Nintendo Switch, will soon let players explore its alien depths through iOS and Android devices.

Subnautica delivers a unique survival experience that blends scientific curiosity with deep-sea dread. Stranded on an aquatic alien planet, players must navigate increasingly dangerous depths to uncover resources, advanced technologies, and the mystery behind their crash landing. The 2018 release has received numerous free updates and spawned the standalone expansion Subnautica: Below Zero, both praised for their rich narrative and immersive world-building.

Having sold over 5 million copies and earned its place among history's greatest indie titles, Subnautica partners with mobile specialists Playdigious (Little Nightmares Mobile) for this adaptation. The complete experience comes to smartphones with optimized touch controls, full controller support (including MFi compatibility), and cloud saves that sync progress across Apple and Android devices. Performance enhancements specifically target iPhone 15 models for optimal gameplay.

Priced at $9.99 with a 10% pre-order discount, this marks the first time the survival classic becomes truly portable beyond the Switch version. While no plans exist yet for Below Zero on mobile, this release coincides with developer updates about Subnautica 2, which promises cooperative multiplayer and a brand new planetary setting when it enters early access later this year.
