Jan. 2025

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.

Jan. 2025

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.

Dec. 2024

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.

July 2024

Below Zero is not a downgrade, it is simply a small sidestep. The only reason people give this game a negative review is because the original Subnautica was so amazing. If Below Zero were judged independently, without the shadow of its predecessor it would be considered a masterpiece just as the original is. It should be noted for those unaware, this is NOT a sequel to the original game; Below Zero is a SPIN-OFF. Subnautica 2 is currently in development and is likely to be much more comparable to the original game.
