If you’ve spent hours scanning alien fish, building underwater bases, and avoiding reaper leviathans on the original Nintendo Switch, you’re probably already hyped for Subnautica Switch 2. The next-gen Nintendo console promises to fix almost every frustration players had with the original Subnautica port, from blurry textures mid-exploration to frame drops when you’re gliding through a school of glowing reefback leviathans. I’ve put over 200 hours into Subnautica across three different platforms, so I’ve broken down exactly what to expect from Subnautica Switch 2, plus actionable tips to prepare for your first playthrough when it drops.
How Subnautica Switch 2 Fixes the Original Port’s Biggest Pain Points
Anyone who played Subnautica on the original Switch will tell you the port had its flaws. Dynamic resolution often dropped as low as 540p in handheld mode when you entered dense biomes, and frame rates regularly dipped below 20fps when you were near large creatures or complex base builds. Even loading into your save could take up to 90 seconds, which killed a lot of the momentum for short play sessions on the go. Even if you never had major issues with the original port, you’ll notice a huge difference the second you boot up Subnautica Switch 2 for the first time.
The upgraded hardware of the Switch 2 fixes almost all these issues entirely. Native 1080p handheld resolution and 4K docked support means you’ll be able to see every tiny detail of the alien seabed, from the glow of bioluminescent plants to the scales of small, fast-moving peepers. Locked 60fps across all biomes eliminates the stutters that used to happen when you encountered a reaper leviathan or entered the lava zones. 2x faster load times cut save and biome transition waits down to less than 30 seconds, even for players with massive, multi-room base builds. I remember once I was being chased by a reaper leviathan near the crash site, and my game froze for 3 full seconds right as it was about to bite me. I lost all the rare materials I’d spent 2 hours collecting, so the frame rate stability alone makes the new port worth picking up for long-time fans.
New Gameplay Features Exclusive to the Switch 2 Port
It’s not just performance that’s getting an upgrade, either. The development team has added a handful of exclusive features and content for the Switch 2 port that you won’t find on any other console, even PC. All of these small upgrades come together to make Subnautica Switch 2 feel far more polished than the original port. The exclusive Lava Cove biome is a great addition for long-time fans, and it fits perfectly into the existing lore of Subnautica Switch 2 without feeling tacked on.
- HD rumble integration that simulates water pressure, leviathan movements, and resource mining feedback, so you can feel distant roars before you see the creature making them
- Handheld touchscreen controls for fast inventory management and base building, so you don’t have to fumble with joy-cons to rearrange your tools or place a bulkhead
- Exclusive Lava Cove biome with 3 new creature types and 2 unique crafting recipes, including a heat-resistant diving suit upgrade that lets you explore deeper lava zones for longer
- Full joy-con gyro support for precise scanning and camera control, making it far easier to line up scans of fast-moving creatures or small, hidden resources
None of these features are game-breaking on their own, but they add a layer of immersion you won’t get on other platforms. I’m most excited for the gyro scanning, because I always struggled to line up scans of fast-moving peepers on the original Switch joy-cons, and I missed out on unlocking a lot of creature entries because of it.
Tips to Prepare for Your First Subnautica Switch 2 Playthrough
Whether you’re a returning player or brand new to the Subnautica universe, there are a few simple steps you can take to make your first playthrough as smooth as possible. If you’re a new player, you don’t have to play the original Switch version first – Subnautica Switch 2 is the definitive portable experience, so you can jump right in without missing anything. You can also pre-load Subnautica Switch 2 a full 3 days before launch if you buy it digitally, so you can start playing the second it unlocks.
First, if you have an existing save on the original Switch, back it up to the cloud now, so you can transfer it over as soon as the port launches. You won't lose any of your base builds or scanned creatures, which saves you dozens of hours of work. Second, make a list of biomes you never got to explore fully on the original port, because the higher resolution and faster load times make deep exploration far less frustrating. I never finished exploring the Lost River on my original Switch playthrough because the frame drops got so bad every time I went below 500 meters, so that’s first on my list. Third, if you’re a new player, don’t look up too many story spoilers before you play. Half the fun of Subnautica is the surprise of finding a new alien structure or encountering a leviathan for the first time, and the improved graphics make those moments hit even harder. Also, invest in a good anti-glare screen protector for your Switch 2 if you plan to play mostly handheld, because you’ll be leaning in close to spot small resources like titanium and quartz in the darker biomes, and glare from sunlight can make those almost impossible to see.
Is Subnautica Switch 2 Worth Buying If You Already Own It On Another Platform?
This is the question I’ve gotten most from friends who already own Subnautica on PC or PS5, and the answer depends entirely on how you play games. If you frequently travel or play games in bed, Subnautica Switch 2 is easily worth the full price tag. The portable performance is even better than the PS4 version in most cases, which is wild for a handheld console. If you already own the game on PC with a stack of mods, you might still find Subnautica Switch 2 a fun change of pace for casual play sessions when you don’t want to sit at your desk.
That said, there are cases where it might not be worth the cost. If you only play docked and already own the PC or PS5 version that runs at 4K 60fps, you might not get enough new content to justify the purchase. The exclusive Lava Cove biome only takes about 2 hours to fully explore, so it’s not a huge amount of extra content for the price. If you’re a casual player who only beat the main story once and rarely plays portable games, you can probably skip the repurchase. But if you’re a diehard fan who’s replayed the game three or more times, the quality of life improvements and exclusive content make it well worth the cost. I already own it on PC and Switch, but I’m picking up the Switch 2 port day one just to be able to explore the Lava Cove and play while I’m traveling for work. There’s no word yet on whether Below Zero will get a separate Subnautica Switch 2 port, but it’s likely if the first port sells well.
At the end of the day, Subnautica Switch 2 is the best portable version of the game we’ve ever gotten, and it fixes almost every complaint players had with the original Switch port. Whether you’re a long-time fan who’s logged hundreds of hours on other platforms, or a new player who’s never explored Planet 4546B before, it’s a fantastic way to experience one of the best survival games ever made. If you’ve been waiting for a smooth, portable version of the game that doesn’t sacrifice performance for on-the-go play, Subnautica Switch 2 is exactly what you’ve been looking for. Just make sure to keep your knife and scanner handy the second you drop into the water – you never know what’s lurking in the dark depths just out of sight.
