Description

  • Make sure to check if your device is supported before playing Subnautica!*

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.

Runs beautifully on the S25 Ultra, barely breaks a sweat even at max settings. Seems surprisingly potato-friendly. Loved this game on PC and still love it now.

I am so glad this game is now on mobile!!! Will Subnautica 2 be on mobile, too?

Iconic game that you didn't expect to release on mobile. Runs and optimized well. No game-breaking bugs. Though some of the reapers sometimes have no audio cues and phase through walls, so you might have to just tank the jumpscare. Still a great game. Too much water though 10/10.

stupid upgrades are not showing up in the modification station so are the prawn arms, and the heat generators dont work they are showing 75 but they just dont give me any power and I used the energy power lines. it runs great but my phone is really good so expected that. hate the tutorials people made absolutely useless and if you make a map of the whole world ve kind enough and include the 4 dumb directions of the world. I was having fun now Im angry, also the time capsules are bugged.

nothing is missing from the original. You need a good phone to run it because the engine it was made on isn't made for Android but if you have a decent phone you'll have a near experience like playing on a console. I couldn't find anything missing from the original, even the developer menu was there.

Amazing

Of course this game is amazing, but this port adds so much quality of life that I wish was in the console versions. Still an 11/10 game

saving issues - manual as well as auto

i’ve spent an entire hour trying to get through 10 minutes of gameplay on a new save. As soon as the first autosave hits, i’m locked out and I have to force quit. The progress is saved up to 9 minutes, so I try again. Turned off auto save as instructed. Got one manual save done at that backup save point. 2 minutes further in I try to take a few supplies back to the ship, manual save locks me out too. I previously deleted the app right after i bought it due to the same errors. It sucks because i LOVE this game so much and i want to play it so badly, but unfortunately i am not able to. (ipad pro 11in 2nd or 3rd gen, probably not on the latest software update to be fair)

Annoying death

Same as voidstar once a reaper went through a cave and found me so annoying that they get a advantage to get you
