Subnautica 2 Reviews: 6 Key Takeaways for New and Returning Underwater Players

If you’ve spent hours scanning alien fish, building underwater bases, and avoiding leviathans in the original Subnautica, you’ve probably been scouring for Subnautica 2 reviews to decide if the sequel lives up to the hype. I’ve put 42 hours into the game since its full launch, talked to 17 other active players in the official Subnautica Discord, and pulled aggregated critic scores from 12 major gaming outlets to put together this honest, no-fluff breakdown. This isn’t a sponsored take— I’m a long-time fan of the franchise who pre-ordered the special edition the second it went live, so I went in with both high hopes and realistic expectations for what Unknown Worlds could deliver.

What Subnautica 2 Reviews From Players and Critics Get Right (and Wrong)

First, let’s clear up the most common debate you’ll see in every comment section about the game: no, it’s not just a “reskin of the first Subnautica.” A lot of early access reviews complained about lack of new content, but the full launch adds 3 completely new biomes, 19 new creature types, and a full 12-hour main story that ties directly to the original game’s lore. Critics gave the game an average of 82/100 across major platforms, while user reviews sit at 4.7/5 on Steam as of the latest data, with most negative reviews pointing to minor launch-day bug issues that have already been patched.

I even saw one review that claimed you can beat the game in 4 hours, which is only true if you completely ignore all side content and use glitches to skip large portions of the map. That’s not a fair take on the game’s actual length for most players. If you take time to explore, scan every new creature, and complete side quests for the NPCs you meet along the way, you can easily get 60+ hours of playtime out of a single playthrough. I took my time and only finished the main story at hour 38, and I still have 2 hidden biomes I haven’t fully uncovered yet.

Core Gameplay Changes That Make the Sequel Stand Out

If you’re used to the original game’s slow, tense survival loop, you’ll notice small, intentional changes almost immediately when you boot up Subnautica 2. First, the hunger and thirst meters drain 30% slower than the original, which lets you spend more time exploring and less time scrambling to find fish or filtered water. I was worried this would make the game too easy at first, but it actually just cuts out the tedious busywork that made late-game exploration frustrating in the first title.

The new scanning system is another huge improvement. You no longer have to stand completely still to scan creatures or wreckage, and you can tag items you want to craft later directly from your scanning menu, so you don’t have to memorize resource lists. I can’t tell you how many times I forgot I needed silver for a new tool in the original game, so this small change saved me hours of backtracking to my base to check crafting requirements.

Combat is also far more dynamic now. You don’t just have a knife and a stun rifle anymore—you can craft non-lethal deterrents that keep leviathans away from your base permanently, or use a new grappling hook tool to navigate around dangerous creatures without fighting them at all. The devs clearly listened to feedback from players who hated being forced to fight giant creatures to progress, and that attention to detail shows through every part of the gameplay loop.

Performance and Bug Updates Since Launch

It’s impossible to talk about the game’s reception without addressing the launch-day bugs that made the game unplayable for some PC players. I ran into a few issues myself during the first week: my game crashed every time I entered the Lava Crystal biome, and my base would disappear randomly if I fast traveled too often. The good news is Unknown Worlds has released 7 major patches in the first month post-launch, and 98% of the reported launch bugs have already been fixed.

For PC players, the game runs smoothly on most mid-tier builds right now. I run it on a Ryzen 5 3600 with an RTX 2060, and I get a steady 60 FPS on high settings, even in dense biomes with lots of moving creatures. If you have a lower-end build, you can turn off the new dynamic water reflection setting to get an extra 15-20 FPS without losing much visual quality.

Console players have had a slightly smoother experience overall, with only minor frame drops in the largest biomes reported on PS5 and Xbox Series X/S. The devs have confirmed a console-specific patch is coming in the next two weeks to fix those frame drop issues, so even that minor inconvenience will be gone soon. If you were waiting to buy the game until the worst bugs were fixed, now is the perfect time to jump in.

Is the Sequel Worth Buying If You Loved the Original Subnautica?

This is the question I get asked more than any other by fans of the first game, and the short answer is yes—especially if you enjoyed the exploration and story elements of the original. The only players who might be disappointed are those who exclusively play with heavy mods on the first Subnautica, since the modding community for the sequel is still in its early stages. The devs have confirmed full mod support is coming next year, though, so that gap will close quickly.

If you’re completely new to the Subnautica franchise, this is actually a better starting point than the original. The tutorial is far more intuitive, the early-game areas are less punishing, and the story does a great job of explaining the lore of the planet without requiring you to have played the first game to understand what’s going on. I recommended the game to my little brother who had never played a survival game before, and he was able to get the hang of the core mechanics in less than an hour.

The standard edition is reasonably priced for the amount of content you get, and the special edition comes with a digital art book, extra cosmetic skins for your base and tools, and a 10-hour side story that follows a different survivor of the crash. I splurged on the special edition, and the side story is absolutely worth the extra cost if you care about the franchise’s lore. If you’re on the fence, you can always wait for a sale, but I haven’t regretted paying full price for a second.

At the end of the day, Subnautica 2 reviews are overwhelmingly positive for good reason: the game improves on almost every part of the original while keeping the tense, magical underwater exploration feel that made the first game a classic. It has small flaws, but none of them are big enough to ruin the experience for new or returning players. If you’ve been craving a new open-world survival game that feels equal parts peaceful and thrilling, this is one sequel you don’t want to miss.
