So, talking about the game itself, what I like the most is that the atmosphere brings a lot of that vibe that Subnautica had. Most developers don't really manage to make the second game as or nearly as successful as the first, but I would say that this is not the case. It has the same fear factor as the first game: the sounds in the distance that you don't know where they're coming from, the fear of the depths, the creatures that are part of the ecosystem and are also dangerous instead of being put there just for cheap jump scares, that constant feeling of the unknown which becomes even stronger at night. I also like the fact that there aren't any guides or tutorials at the moment and that's cool because discovering things on your own is something that puts you more into the lonely vibe that Subnautica has. Some of these feelings go away after you get past the beginning and you're not as vulnerable anymore, but that's normal and it was the same in the first game. So as a short summary of the game, it's really cool because it resembles the first one in vibe but the graphics are much cooler and modern, you can build more complex bases and be much more creative on this side, the storyline is engaging, the addition of co-op and being able to play with friends, the vehicles are fine but honestly I miss Cyclops a little, the map and biomes are interesting and currently still have that new and unknown factor, the audio is really cool just like in the first game, and with the optimization I haven't had any problems so far but I also have a higher-end PC, but anyway I have no concerns about optimization because I'm sure it will only improve until the game comes out of early access. Now about Krafton, which I'm glad isn't on the publisher or developer list next to Unknown Worlds Entertainment. I think they wanted to help us get into the game's atmosphere a little and they decided to do their best Alterra roleplay :)) I'm not surprised that this EULA is trying to limit the user's rights and that the company is trying to grant itself powers that it may not actually have, because it reminds me of what happened between Krafton and the original Unknown Worlds leadership shortly before the Early Access launch, when many people believed the company was trying to avoid paying the $250 million earnout bonus (which I hope they'll receive now based on the number of sales at launch), but I'm glad that in the end it came to light that Krafton violated certain contractual obligations when it took control of the Unknown Worlds studio and that the court mostly ruled in the developers' favor. Regarding the EULA itself, Krafton is neither the first nor the only company to have such an aggressive EULA, but I think the previous discussions have made people read the terms more carefully and probably since we were already angry with Krafton, this EULA only made us angrier. Anyway, I'm not really stressed out by all the nonsense they wrote there because in the EU at least where we have stronger consumer protections, I could say that many of those clauses may not be enforceable, and clicking 'Accept' does not make local laws disappear, nor does it automatically remove rights that consumers are legally entitled to. And finally, I rated the game positively because Unknown Worlds deserves it. My issues are with Krafton, not with the developers who put years of work into making a worthy successor to the original Subnautica.
TLDR Summary: The base building is incredibly intuitive and the best it's ever been, the new Tadpole vehicle feels great, and the isolated, creepy vibe of the first Subnautica is totally back. However human models look uncanny, and the map feels a bit empty and restrictive right now. The biggest issue is that the devs removed all forms of lethal self defense due to a forced pacifist design philosophy. Against giant leviathans, your only options are throwing useless flares or running away. But there is massive potential. Going into this with the recent Krafton news I was honestly pretty worried but I was actually surprised. It's very much an early access title right now: it's a little raw and the map feels small when you start out. If you swim in some directions you hit the void wall in just a few hundred meters. I know the map stretches for thousands of meters east, but even in those huge areas there's barely any fauna or detail. Hitting those sudden walls makes the immediate playable space feel pretty restrictive. There are no real main objectives yet so you can't really "beat" the game. Afaik the only real things to do are track down a few blackbox distress signals and terminal scans which you can do fairly quick. But what is there is very playable and enough to just have fun exploring. Visually the game looks gorgeous. The new UI is futuristic and pretty and the music is actually pretty sick. But honestly where the game really shines right now is the base building. You can dynamically scale things like walls and rooms and the whole system just feels super intuitive and fun to mess around with. I also gotta give a massive shoutout to the Tadpole. Even though it's the only vehicle right now it hits a really good sweet spot. It has that fun modularity from Below Zero but keeps the normal smooth functionality of the first game so it doesn't feel terrible and sluggish to drive. There are definitely some issues though. BE AWARE OF TROILITE SOFTLOCKS (one of the mid-late game resources). Troilite currently does not respawn in the world. If you mine the available nodes and use it all up making ingots, your entire save gets completely softlocked and you cannot progress. The devs dropped a hotfix adding more Troilite to the late game region so this is less likely to happen now. On the less severe side the human character models look horrendous right now. They are super uncanny and honestly look AI generated lol. I also really wish we could enter the new lifepod from below like in the first game even though the new design itself looks pretty cool. Speaking of things that miss the mark I have to mention the game's new seaglide called the Wakemaker. I like the design but it is extremely slow and honestly just feels useless right now. The FOV is also a tad too low which is nauseating for me so I really wish we had a FOV slider. And then there is the performance. I originally thought it was just a bit demanding, but honestly it is horribly optimized. It relies way too heavily on Lumen, to the point where it brings even the best rigs to their knees. I saw a Zwormz benchmark where the game couldn't even hold 60 FPS at 1080p on Epic settings with DLAA... using an RTX 5090. That is just unacceptable. To make matters worse, the upscaling is currently just bad and suffers from really noticeable ghosting. They just rolled out a hotfix targeting performance on Epic visual settings which is a step in the right direction, but optimization still has a very long way to go. One of the first things I noticed was the new PDA voice. I didn't like it at first but it kinda grew on me and feels a little more intimidating when it warns you about things. But what is most notable is the new "NOA" ai assistant. It acts like the radio from the older games but gives you cool audio logs to read through. That actually got me to bother reading into the story which is a first for me. The game's vibe is much closer to the original Subnautica than Below Zero. You have a silent protagonist again so there's no constant character narration and the feeling of complete isolation is back since the only voices you hear are NOA and the dead crew's logs. The game does have its own void monster which made me happy (sounds stupid I know). It makes these scary wails and looks pretty terrifying. There's also the Collector leviathan which is a giant squid, but I found the design to be a bit underwhelming compared to the massive ones they showed in the cinematic trailer. Gameplay wise they are also a massive pain. The border between the Shallows and the eastern Observatory is extremely annoying to get across because of the Collector leviathans patrolling it. It is completely impossible to combat them in any way right now. There is no way to defend yourself and if you're caught say goodbye. I've found flares to be completely useless. Throwing one feels like slapping them with a napkin. You basically just have to slam the gas and pray you don't get bent over. The most glaring flaw in this game is the absolute lack of self-defense against predators; being forced to either toss a flimsy flare or simply swim for your life is a deeply frustrating design philosophy. I realize the franchise has always leaned away from traditional combat, largely driven by the director’s decision to project real-world political views onto a sci-fi survival setting which is a connection that has always felt completely misplaced. But even with those restrictions the original game still gave you a survival knife and a stasis rifle to hold your ground. In this sequel even those fundamental lifelines have been stripped away, and the development team's justification for it is severely disappointing. The irony is thick enough to cut with the knife they took from us. They act as though removing basic survival mechanics from a video game somehow addresses real world violence. It’s completely contradictory to mandate "peaceful exploration" when the ocean is actively trying to eat you. Furthermore the hypocrisy is staggering. This supposedly pacifist game loop has no moral issue with players feeding endless hordes of innocent non violent fish into a fabricator for sustenance yet completely draws the line at letting us protect ourselves from actively aggressive sea monsters. I fully respect their creative right to build the game they want to build. However if this forced helplessness is the idea for the franchise going forward, I will definitely not be buying the next game. Aside from the Collector and Void leviathans there are only about a dozen other hostile creatures in the game right now like Bulletheads and Needlersharks. Honestly these smaller predators are mostly completely unharmful and act more like a bother than anything else. The only actual threats right now are the two big leviathans, so 13-ish enemies that rarely bother you unless youre up in their face isn't exactly tons of predators. However, digging through the game files does reveal massive untextured prototypes like an "Elusive Leviathan" that is 217 METERS LONG (double the size of the Sea Dragon and four times longer than a Reaper). There are also already ideas for a successor of the Cyclops called the "Trident". So while the game feels a bit empty on day 1 when it comes to the fauna, the foundation for a much bigger experience is clearly already in the works. There is also a massive uproar right now regarding the game's EULA and data collection policies. To be honest the text itself is mostly standard corporate stuff like class action waivers and telemetry that you see in every modern online game but it's worth mentioning. Fortunately it looks like the devs listened to the backlash because a hotfix just revised the ToS and added a clear in game prompt letting you toggle off telemetry at any time. Overall, I think the potential is great, but buy it to build and explore.
