A frozen-ocean survival game on an alien planet where building a base and diving deeper are their own kind of therapy, if you can handle the dark.

Subnautica: Below Zero is the standalone follow-up to the original Subnautica, set two years after the events of that first game and returning players to Planet 4546B, this time to a biome locked in permanent arctic conditions. You play as Robin Ayou, a researcher who arrives on the planet chasing answers about her sister's disappearance and quickly discovers that the corporation behind the operation is hiding something genuinely ugly. The story is more front-and-center here than in the original, delivered through audio logs, ghostly psychic transmissions, and a peculiar AI companion who shares headspace with Robin. Whether that added narrative focus is a gift or a distraction will depend entirely on how you felt about the first game's near-silent protagonist approach. The core loop is the same satisfying rhythm: descend, scan lifeforms, gather materials, surface before your oxygen runs out, craft better gear, descend further. The alien ocean does its job. Thermal lilypads, shadow leviathans, the low pulse of bioluminescent creatures in deep water, the world is built with genuine care for atmosphere. A new land component introduces a snowy surface biome where you can explore on foot, drive a snowfox hoverbike, and encounter creatures that feel appropriately out of place on an ocean-centric planet. It is a welcome expansion of the formula, even if the surface areas feel slightly less polished than the underwater zones that clearly received more love. Where Below Zero earns its keep is in moment-to-moment exploration. Stumbling across a new biome at depth, hearing the music shift from tense to melancholic, realizing the creature ahead of you is enormous and curious rather than hostile, these are the moments the game is built around. The soundtrack leans into a colder, more crystalline palette than the original and it works. The habitat building system remains one of the most tactilely satisfying in the genre, letting you construct underwater bases that feel earned rather than arbitrary. Seabases, moonpools, fabricators, the quiet hum of a power cell charging while you organize your storage, it sounds mundane but it is genuinely calming in a way few survival games manage. The criticisms are real though. The story, for all its ambition, stumbles in the back half. Pacing issues surface around the midpoint where the narrative momentum stalls and the game starts throwing fetch-quest-shaped objectives at you without quite enough payoff. Some players find Robin's voiced dialogue charming; others find it breaks the quiet immersion the original built so carefully. The leviathan-class creatures are terrifying in the best way early on, but resource grinding can push you back through familiar territory enough times that the fear dulls into routine. It is a shorter experience than the original by most accounts, and a handful of biomes feel underdeveloped compared to the dense, rewarding zones that clearly got more attention. If you played the first Subnautica and loved it, Below Zero is worth your time as a companion piece rather than a successor. It is smaller, slightly messier in ambition, and does not fully replace what made the original feel so singular. But it is also quietly beautiful in its own frozen register, and for players new to the series, the more structured story might actually be an easier entry point. Unknown Worlds built something worth sitting with, even when it does not entirely stick the landing. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
