### 5/5 — Casserole 🥘 dish with chicken 🐓 chili 🌶️

*2026-07-31*

The game is grad season for me too but it’s still fun 🤩 and I’m not sure if it’s the same as the other game though but it’s definitely worth it

### 3/5 — What did I do to deserve this treatment?!

*2026-07-04*

Hello game devs of Subnautica below zero there was a problem about the trivalve that you need to fix before it happens again the problem is that when I had a trivalve which was normal at first but then later it just vanished so then I had to find the other egg please fix this if you don’t my second trivalve is going to vanish too.

### 5/5 — Шикарный порт, шикарной серии игр

*2026-06-27, version 1.0.3*

Отличная оптимизация, не верится в то, что мы дожили до времени, когда можно играть на своем смартфоне в такие игры. Вас очень любят в России, ребятки, спасибо, что вы есть

### 2/5 — great game

*2026-06-26, version 1.0.3*

originally i would rate this 5 stars, as I LOVEE subnautica but recently, i cant play either games. it keeps me on the warning screen,and it sucks as i have no other way of playing subnautica. PLEASE FIX THIS GLITCH!!!!

### 5/5 — Can’t steer easily.

*2026-06-25, version 1.0.3*

On my snow fox it’s hard to steer, because I have turn my camera half way across my screen to  steer. 

Great game though.

### 5/5 — Console Commands!

*2026-06-16*

I love this port, it basically has everything the original game has but honestly less bugs. I originally said console commands didn’t work, but just putting my fingers slightly lower on the screen than in the Subnautica port made them work (and now I feel stupid lol). Fantastic job by Unknown Worlds - cannot believe this is running on a phone.

**Developer response:** You can access the console the same way, try to reposition your fingers !

### 5/5 — Not a bad sequel.

*2026-06-10*

Areas are smaller and the land component was new, however the game was very satisfying. I would have liked to have known more of what occurred with the character from the 1st game but otherwise it was very enjoyable. That being said there were several audio bugs, msgs repeating or not popping up in areas where an action should have initiated a new msg or objective note. It was workable but I was forced to disable the audio rather than listen to 30 minutes of a repeating msg.. Apart from the audio bug the game has a nice added component of a companion or ongoing relation/conversation with an NPC..the sea truck was a nice addition, having a mobile supply/manufacturing set made life easier and added aspects to the gameplay that I felt were more enjoyable than the previous game, looking forward hopefully to subnautica 3 on the mobile

**Developer response:** Thank you for your review!

### 5/5 — ABSOLUTE CINEMA

*2026-06-09, version 1.0.3*

Best game ever worth buying 
Very good graphics 
Don’t set the graphics to very high. Trust me your house WILL burn down 😂😂😂

### 4/5 — Mostly excellent, though I did experience one problem.

*2026-06-04, version 1.0.3*

When I started out playing, I did not seem to have any problems but later on after a certain point, the game started stuttering every like 10 seconds, I am on a iPhone 17 by the way. I believe it is something to do with items in the sea truck storage module chests because after I removed most of the items I had in it, I stopped experiencing as much lag and stuttering.

### 4/5 — My report on Subnautica below zero

*2026-06-03*

There was a few issues that made it not a five star game for me because I tried getting gel sack seeds but when I tried getting the gel sacks when they got put into open water they phased through the ground also when I saved me game it took me back to when I was getting the snow fox which was 30 minutes before I saved these were pretty annoying since I had to scan all the items and get the gel sacks

**Developer response:** Thank you for your feedback, it has been passed on to the team!
