There’s no game that feels more made for virtual reality than Subnautica. Floating through the bioluminescent depths of Planet 4546B, ducking past schools of alien fish and tensing up at the distant roar of a Reaper Leviathan hits entirely different when you feel like you’re actually in the water. If you’re wondering how to get Subnautica VR on Oculus Quest 2, you don’t need any fancy technical skills to get it up and running. I’ve tested both official and modded setups over the past year, and this guide covers every step you need to follow, plus common fixes for issues that pop up.
How to Get Subnautica VR on Oculus Quest 2: 2 Valid Methods Explained
First off, you have two fully functional ways to play Subnautica VR on your Quest 2, and the right one for you depends almost entirely on whether you have a mid-to-high end Windows gaming PC. Neither method requires you to pay for extra copies of the game, as long as you already own a legitimate base copy of Subnautica, and both give you full access to the main game’s story and content.
The first method is using Oculus Link (wired or wireless Air Link) to run the official VR beta of Subnautica from your PC to your headset. This is the most stable option, with full official support from the game’s developers, and it works with your existing game saves. The second is a fan-made standalone mod that lets you play without a PC at all, sideloaded directly to your Quest 2. It’s less stable, but perfect for people who want to play on the go without being tied to a desk.
Step-by-Step Setup for Oculus Link (No Mods Required)
This is the method I recommend for most people, because it’s far less likely to have game-breaking bugs, and you don’t have to jump through hoops to get updates. You need a copy of Subnautica on Steam or Epic Games Store first, as the VR support is built into the official game’s beta branch, no extra downloads needed.
Before you start, make sure you have all the required gear to run Oculus Link smoothly:
- Windows 10 or 11 gaming PC with at least an NVIDIA GTX 1060 / AMD RX 580 equivalent GPU
- USB 3.0 cable for wired Link, or 5GHz WiFi 6 router for wireless Air Link
- Updated Oculus PC app and latest Quest 2 system firmware
- Legitimate copy of Subnautica purchased on Steam or Epic Games Store
Once you have everything ready, open the Oculus PC app, connect your Quest 2 to your PC via cable or enable Air Link from your headset’s quick settings. If you’re using Steam, right click on Subnautica in your library, select Properties, go to the Betas tab, and opt into the “vr” beta branch. The game will automatically download the VR update in a few minutes. For Epic Games Store users, you just need to add the launch command “-vr” to the game’s settings to boot into VR mode.
Make sure you turn off VR motion blur in the in-game settings before you start playing, as this is the number one cause of motion sickness for new Subnautica VR players. You can also adjust the movement mode to teleport if smooth locomotion makes you dizzy, though I found smooth movement feels far more immersive once you get used to it.
How to Install the Standalone Modded Version (No PC Needed)
If you don’t have a gaming PC, or you want to play Subnautica VR while traveling or away from your desk, the fan-made standalone mod is your best bet. It’s been in development for years, and the latest versions run surprisingly well on the Quest 2’s native hardware, with only minor frame drops in the busiest biomes like the Lost River.
First, you’ll need to enable developer mode on your Quest 2, which you can do for free by registering as a developer on the Meta website and toggling the setting in the Oculus mobile app. Next, install SideQuest on your phone or PC, which is the trusted platform for sideloading legal, fan-made VR content to your Quest 2. Search for the Subnautica VR mod on SideQuest, and follow the prompts to install it directly to your headset.
You will not be able to access official game saves with the standalone mod, so you’ll have to start a new playthrough from scratch when you first launch it. You’ll also be asked to input the license key from your existing copy of Subnautica to verify you own the game, so don’t try to pirate it – the mod won’t work without a legitimate key, and you risk getting your Meta account banned if you download pirated versions.
Never download the mod from untrusted sources outside SideQuest, as random websites hosting the mod often include malware or stolen account credentials. The SideQuest version is vetted by the modding community, so it’s the only safe option to use. The biggest downside to this method is that there’s no official support, so if you run into a bug that crashes your game, you’ll have to look for community fixes on Reddit or Discord.
Tweaks to Make Your Subnautica VR Playthrough Smooth and Comfortable
Even if you get the game running perfectly, there are a few small tweaks that will make your playthrough way more enjoyable, especially if you’re new to VR. The first thing I do when I boot up Subnautica VR is turn off head bobbing and reduce the field of view blur by 50% – those two changes cut my motion sickness down to almost zero, even when I’m swimming at full speed through tight cave systems.
If you’re using Oculus Link and getting consistent frame drops, try lowering the render resolution in the Oculus PC app by 10-20%, and turn off ambient occlusion and anti-aliasing in the in-game settings. You won’t notice much of a visual difference, but you’ll get far smoother performance, which makes a huge difference in comfort. For standalone mod users, lower the draw distance in the mod’s settings menu to 70% if you’re getting frame drops in open areas like the Crash Zone.
Invest in a good weighted VR face cover if you plan to play for more than 1 hour at a time to reduce neck strain and sweat buildup. I also wear a cheap waterproof sweatband when I play, especially when I’m exploring deep areas where Reaper Leviathans spawn – there’s nothing worse than having sweat drip into your eyes right as a giant sea monster jumps out at you. I also keep a bottle of water next to my play area, because it’s easy to get so immersed you forget to drink for hours.
Whichever setup you choose, learning how to get Subnautica VR on Oculus Quest 2 opens up one of the most immersive gaming experiences you can have right now. I’ve put over 80 hours into the VR version of the game, and I still find new details and hidden areas every time I play. If you run into issues with either setup, the active Subnautica VR modding community on Reddit has fixes for almost every common bug, so don’t give up if it doesn’t work perfectly on your first try. Just remember to take breaks every hour, and don’t scream too loud when you first see a Reaper Leviathan – your roommates will thank you.
