The world of video games is vast, bringing together a wide variety of themes and narratives that let players enjoy diverse universes packed with all sorts of details that cannot be appreciated in other formats. They can even serve as a setting in which to overcome certain fears and tackle sensitive issues such as mental health, as numerous titles have demonstrated over recent years. With all this in mind, the social and educational dimension of video games is increasingly present in the products reaching the market.

It was with this aim of offering greater support to players that Subnautica emerged, a title that invited players to explore the seabed and which could be the perfect option for overcoming the thalassophobia that grips a large part of the population while also uncovering the secrets hidden in this largely unexplored terrain. However, Unknown Worlds wanted the project to lean into the survival genre, where you must gather specific resources to make progress in a hostile environment dominated by a host of dangers such as the flora and fauna lurking in the darkness of the deep.

Following the game’s success, the studio has wasted no time launching Subnautica 2, which is making its debut in early access—an increasingly common practice in the industry that lets players enjoy the title ahead of release and provide feedback to help refine the experience until the desired result is achieved. The aim of this sequel is clearly to deliver a more complete game with broader options, playable by up to four players in co-op.

A survival adventure at the bottom of the sea

This new instalment puts players in the shoes of one of the Pioneers aboard the CICADA, an Alterra colonial ship that was supposed to guide them towards a new life far from the conflicts of their home world. However, following a serious setback that derails the original plans, the crew finds itself stranded, with the ship’s AI firmly insisting that the mission must continue at all costs. With the fate of humanity in their hands and the odds stacked against them, survival becomes an immediate imperative in a completely unknown aquatic environment that doesn’t seem particularly keen on welcoming guests.

To adapt to the depths of this new and imposing alien world, players will have a revamped technological arsenal at their disposal. The Tadpole submersible will become their best ally for exploring the planet’s various biomes, serving as a spearhead before venturing into the deepest and most dangerous waters. Unsurprisingly, the design and customisation of underwater bases will once again be a cornerstone for securing safe havens away from the shallows, a system that will expand with new tools, vehicles and upgrades as early access progresses.

The main appeal of Subnautica 2 lies in its gameplay. Although designed as a single-player experience, the game also lets you tackle the challenge in online co-op with up to three friends. You can choose from four pre-designed characters to coordinate the exploration of long-forgotten ruins and study the planet’s rich biodiversity. Scanning and researching everything from the tiniest creatures to the imposing Leviathans will be crucial not only for survival, but also for unravelling the true reason why the ship’s AI is so obsessed with pressing on.

More biological variety, more dangers

The real driving force behind this sequel isn’t just gathering materials to ensure the Pioneers’ survival, but the deep scientific research element that Unknown Worlds has woven into the heart of the game. Scanning the local flora and fauna ceases to be a mere cosmetic addition and becomes the key that unlocks new advanced technologies. Every discovery in the depths provides crucial data on how this planet’s organisms interact with the remains of the ancient civilisations that once inhabited it, forcing players to act as true biologists and archaeologists in a hostile environment.

This constant need for exploration pushes the boundaries of the map into areas of breathtaking beauty and ever-present danger in equal measure. The fauna—ranging from tiny bioluminescent creatures that react to torchlight to colossal alpha predators capable of swallowing entire vehicles—now displays far more complex behavioural patterns than in the original title. Understanding how these species behave and learning to camouflage yourself or fend them off will determine the success of any expedition into the darkest trenches, where water pressure and poor visibility turn every foray into a genuine exercise in tension.

The sequel is therefore shaping up to be a qualitative leap forward within the survival genre. By so closely intertwining the CICADA’s narrative with pure exploration of this alien ecosystem, the game ensures that curiosity is the main incentive to keep descending. The promise of constantly expanding this universe throughout early access is the best calling card for a game that aims to surpass its predecessor, proving that the ocean of Subnautica 2 is an inexhaustible canvas of surprises and challenges.
