Developer Description

Survive in an underwater open-world

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.

• CRAFT – Build bases to shelter in, vehicles to pilot, tools for survival to aid you in navigating and adapting to this subaquatic landscape.

I can not describe how excited I was to see this game available. This is a game I've wanted to play for a while but didn't have the device needed. Seeing it becomes available on mobile is great. the game is also incredible. the biomes you can explore are all beautiful. The animals are all incredible and fun to interact with (except the reaper leviathans), and the leviathans are as terrifying as one would expect. The prawn suit is my personal favorite vehicle to use. over all the game is amazing.

Just suggestion, hope the team would listen. Since there are many pc games ported to mobile, there's a lot of people invested now on controllers, since we want to play this at a full experience (without visible buttons on screen) I suggested to add a rumble effect just like on pc version for controller. I just think that rumble effect on subnautica would be so great, especially when huge monsters growl or making a deep sound. For now, i'll rate it 4stars, enjoying it for how many days now.

love this game but my only problem is that i can not move the buttons on my screen and the view distance needs to be increased or there needs to be an option to increase it.

Loved this game on ps4 and 5. Mobile version is junk and support is handled by a bot. My Cyclops randomly started strafing to the right and is now stuck against my Base damaging both the base and Cyclops till the Cyclops blows up. Uninstalling, and I think I'm going to take everyone's advice to not support Subnautica 2. It's a shame as the first game was awesome on Playstation. This is what happens when a company is taken over I guess.
