Subnautica: Below Zero in IOS

Walkthrough, Guilds, Tips on this special game

Our Expert Score

95/100

Subnautica: Below Zero on mobile is a technical marvel. It manages to translate the deep, atmospheric survival experience of the PC original to a touch screen without losing any of the tension. The underwater biomes are absolutely breathtaking—the way the light filters through the ice into the deep blue water is something you have to see to believe. It captures that unique Subnautica mix of wonder and absolute terror when a massive Shadow Leviathan suddenly looms out of the darkness.

The mobile controls have been thoughtfully implemented, with the virtual joystick and action buttons feeling responsive enough for the precise movement needed in narrow caves. The crafting system is deep but manageable, and the 'Seatruck' vehicle is a brilliant addition that lets you carry a piece of your base with you as you explore. It’s a massive game with a genuine mystery at its heart, and the survival mechanics (especially managing your body temperature on the frozen surface) add a new layer of strategy that keeps the gameplay fresh. It’s an absolute must-play for survival fans.
