User reviews & Ratings

First off, as this game was originally a dlc-turned-spinoff of Subnautica, I encourage you to read my review of that first, as many of the things I praised about the game I mentioned apply here as well. That being said, let’s dive in! (Warning, a few accidental puns ahead!) For many of you looking to pick up Below Zero, you may have heard of the community's general opinion of how it stacks up against the first game. I however, feel comparison is not the way to go but rather looking at BZ as an extension of the Subnautica universe, and enjoying another dive into 4546B’s oceans. Below Zero has an extremely in depth world and story to explore, and those should not be overshadowed by Subnautica’s existence. That being said, there are many things Below Zero does right. It boasts quite a bit more new features, settings, and content, and they combine to make an engaging and enjoyable experience for fans of Subnautica. First of all, Below Zero’s biome and creature designs are truly phenomenal and make the overall feel of each new area you explore equal parts beautiful and uncertain. From chilling arctic forests, to glittering hollow icebergs, to eerie crystal caverns, one thing BZ has inherited is Subnautica’s impeccable atmosphere. The map is quite a bit smaller in size than Subnautica, but the content is denser. The cave systems are intricate and claustrophobic, making last minute dashes for O2 adrenaline pumping endeavors. The creatures feel even more suited to their environment than Subnautica’s, leading to enhanced immersion and cooler creature interactions. Below Zero’s on land exploration is quite fun as well, and the cold mechanic simulates the restriction of oxygen underwater, reinforcing the feeling of never truly being safe and requiring you to think about your exploration and strategies surrounding heat management. Seeing glowing eyes just barely visible, stalking me in the snowstorm gives me the chills every time. You are less mobile, making you feel more vulnerable, that you’ll become prey if you’re not careful, which is an awesome feeling that makes up the heart of the Subnautica games. Creature concepts are also more involved and can even be cooler than some of SN1’s ecosystem. Few things compare to being chased by a brute shark as you hear the gnashing of its jaws slowly getting louder, to the rumble and shake of the snow as a leviathan burrows beneath it, to the aggressive shriek of a creature you cannot see, but can most certainly see you. There are some really cool additions to bases as well, some enjoyed so much by the community that they were backported into SN1. The large room provides some much needed space, allowing for even more creative builds. The glass domes are breathtakingly beautiful in the right spot, and give some amazing glimpses of the dazzling surface, the colorful flora, and the angry, swimmy things that want to eat you alive. But the true difference between having an extensive underwater seabase and being a glorified submerged can of food is style! The jukebox, art pieces and posters (Yes, there is another kitty one), and multiple decorated beds and furniture allow you to spiff up your seabase to make it your very own. Overall, Subnautica: Below Zero’s aesthetic, story, and ambiance will appeal to both newer players and diehard Subnautica fans. Subnautica: Below Zero is an underappreciated game and a fantastic experience in its own right.

A lot of people say it didn't live up to the first one and I fully agree. But personally, I still liked it and found myself having a lot of fun with it + it scratched that itch that only Subnautica can. Can't wait for Subnautica 2

Cons: - One of the most significant issues is the lack of genuine danger. Unlike the og game, where encounters with creatures like the Reaper Leviathan instilled a constant sense of dread, Below Zero feels comparatively tame. The leviathans, while visually interesting, often feel too cute (Chelicerate is a giant shrimp). - The main story also fails to capture the same level of intrigue as the original. - The significantly smaller map size is a major drawback that impacts several other aspects of the game. The limited space severely restricts exploration, making the potential for deep-sea discovery and large wreck exploration feel wasted. Imo, vehicles like the Seatruck and Snowfox feel not very useful in such a confined environment. The Seatruck, in particular, feels useless, because of the Prawn Suit, especially when suit is equipped with ion power cells. - Below Zero feels slower-paced than the og game. - Resource gathering is far too easy; you can basically find reactor rods almost at the start of the game. Pros: - The penglings are very cool, and you can carry them around! - QoL improvements enhance the gameplay experience; the recyclotron, for example. - The dynamic weather system adds a layer of immersion. - Jukebox jam lesgooo. - Below Zero is more stable and performs better compared to the original Subnautica. - The crafting system feels more streamlined. Overall, the game is still Subnautica at its core, and it's good. Even with all its flaws, I enjoyed it, not for the story, but for the exploration and base building.

Although it has its own issues, its a perfectly functional game which would have been amazing as a standalone, but suffers from having to be a sequel to an excellent game.

If Steam had the option, I would give Below Zero a neutral review. On one hand, it's more Subnautica, so I still had plenty of fun with it. On the other hand, it's inferior to its predecessor in almost every aspect. The game features three storylines, but two of them feel insignificant, with one having a completely missable conclusion. The world design is a step down, with abrupt biome transitions and overly cramped spaces. The new vehicle combines the worst traits of the Seamoth and Cyclops: it is slow and does not fully work as a mobile base. The game has also been made easier and less scary. Taking all these points into account, Below Zero feels like it should have remained a DLC. Despite its flaws, this is still a thumbs up because I enjoyed playing more of my favorite survival game and for the sake of Penglings and Seamonkeys.
