About this game

Subnautica is an underwater adventure game set on an alien ocean planet.
A massive, open world full of wonder and peril awaits you!

Descend into the depths, craft equipment, pilot submarines and out-smart wildlife to explore lush coral reefs, volcanoes, cave systems, and more - all while trying to survive. Unravel the mystery of this world teeming with creatures, both friendly and hostile, scattered with clues from a previous time.

Play in Survival mode to experience the original challenge, or switch to Freedom or Creative mode to discover this oceanic planet without the pressures of thirst, hunger, or oxygen.

FEATURES
• SURVIVE – After crash landing on a vast underwater planet, the clock is ticking to find water, food, and to develop the equipment you need to explore.
• EXPLORE – Manage your hunger, thirst, and oxygen supply as you dive into towering kelp forests, sunlit plateaus, bio-luminescent reefs, and winding cave systems.
• SCAVENGE – Collect resources from the ocean around you. Venture deeper and further to find rarer resources, allowing you to craft more advanced items.
• CRAFT – Build bases to shelter in, vehicles to pilot, tools for survival to aid you in navigating and adapting to this subaquatic landscape.
• DISCOVER – What happened to this planet? What caused you to crash? Can you find a way to make it off the planet alive?
• CUSTOMIZE – Play in Survival mode to experience the original challenge, or switch to Freedom or Creative mode to discover this oceanic planet without the pressures of thirst, hunger, or oxygen.

I love Subnautica, and playing it on my phone has been fun! That said, I really need the devs to fix several issues. 1 The Prawn's walking stutters 2 While Stalker teeth spawning under terrain is a known issue in SN1 on other platforms, it's worse here. EDIT: had to remove stuff to reply, 500 char limit, wanted to say: I know about the method to farm st.teeth, I'm saying this is very buggy in this version, the teeth spawn at min y, edge of the map, or somewhere close to it. rest is fine, ty ❤

Hello, the glitching stalker tooth is indeed a known issue, we're currently working on it ! In the meantime If you bring a scrap metal part to a stalker he will grab it and you'll have a small chance for it to drop a tooth at the same time (it will make a special sound).

Love it so far!! For such an enormous game, it runs insanely smooth and barely gets my S22 Ultra hot while other games do so big kudos to the developers. The only small thing/improvement I'd suggest is the controls. They feel a bit awkward with the hand sometimes but I think I'll get used to that soon. It also took me way too long to figure out how to use and consume stuff in the inventory so maybe a bit more clarity on that in the tutorial. Otherwise, it's just fantastic.

I've been wanting to play Subnautica for the longest of time and I hoped it would be available on mobile and it finally did. Worth the pay on this one, although scaling the resolution and fps to high or very high obviously eats a lot of battery and heats up the device it's still functional and barely no lags. I just can't miss the beauty of this game and the horrors it offers. Thank you Unknown Worlds for the mobile release! We love you more, screw Krafton.
