'Subnautica 2,' the sequel to the hit game developed by Unknown Worlds Entertainment, is set to launch in early access on May 15. The original Subnautica successfully distinguished itself from other exploration games by masterfully blending the human fascination with the 'cosmos' and the 'deep sea.' Riding this wave of success, Subnautica 2 has already climbed to the top of the Steam wishlist. With the benefit of advanced technology, this sequel appears focused on enhancing the core experience of the original while expanding its scale. We took a close look at how Subnautica 2 has evolved ahead of its early access release.

Explore a New, Massive Planet Your Way!

Unlike its predecessor, which supported only a single-player experience, Subnautica 2 offers both solo play and four-player co-op. By providing these two options, the developers cater to both the 'lone wolves' who want to explore the deep sea at their own pace and those who prefer to cooperate with friends to lighten the load.

Lead Designer Anthony Gallegos noted, "While we are focusing on the single-player experience during the early access phase, we plan to actively collect and incorporate feedback regarding co-op after launch," signaling a commitment to balancing both modes.

Furthermore, the setting for this title is not planet 4546B, but a vast, entirely new world, introducing players to unfamiliar landscapes and alien creatures. New lifeforms abound, such as the 'Four-Eye,' where two entities live their entire lives as a single being; the 'Zetocaris,' a crab-like creature that moves as if it has boosters on its legs; and the 'Necroray Jellyfish,' which displays unique bioluminescent patterns at night.

As in the original, a variety of vehicles will support exploration of the expanded world. A new vehicle called the 'TadPole' features a different operating mechanism than the original's Seatruck; it allows players to detach a smaller probe from the main body to explore narrow caves, much like a Matryoshka doll. Additionally, the 'Wakemaker' replaces the Seaglide to assist with smooth personal mobility.

Deeper Progression and Crafting Systems

Progression and crafting, the core elements of survival games, have also been significantly enhanced. Subnautica 2 introduces a new progression feature called 'Biomods.' Rather than replacing the existing equipment crafting system, this system complements it by allowing players to evolve their own bodies using the genes of alien lifeforms. Lead Designer Anthony stated, "Because the total playtime is quite long, we aimed to provide as many recipes as possible, and Biomods are part of that effort."

In addition, base building and crafting systems have been upgraded to offer a deeper experience than the previous title. For base building, internal space partitioning is now more flexible, and features have been added to allow for fine-tuning the shapes of walls and furniture. Furthermore, unlike the previous game where everything was handled through menu screens, the crafting system has been integrated into the building tools to encourage a more natural gameplay flow.

A More Sophisticated Deep Sea Powered by Unreal Engine 5

As a sequel arriving eight years later, the game marks a significant technological leap. Subnautica 2 was developed using Unreal Engine 5 (UE5), and Creative Media Producer Scott MacDonald mentioned that the transition to UE5 was instrumental in realizing a more sophisticated deep-sea environment.

According to MacDonald, Nanite allowed for a world with significantly higher polygon counts and detail, while Lumen helped implement natural lighting, making the light and reflections players encounter feel more realistic than in the original. Indeed, trailers and screenshots reveal greatly enhanced textures for rocks and seaweed, with lighting depictions moving closer to photorealism.

UE5's impact extends beyond the environment to the creatures themselves. In particular, the 'Leviathan,' synonymous with terror in the original, has become even more formidable. Scott added that while creatures and Leviathans in the first game could only consider one action at a time, UE5's 'Behavior Tree' allows them to judge and react to the environment, players, other creatures, and objects autonomously.

Launching May 15, Aiming for Satisfaction Through 'Open Development.'

Looking at the released specifications, the GPU requirements for top-tier settings are relatively low for a game developed in UE5, suggesting good optimization. While 4K/60fps usually requires a 5080-class card, it has been announced that Subnautica 2 can maintain 4K/60fps with a 5070 Ti or 7900 XTX.

In Korea, Subnautica 2 early access will be available starting at midnight on May 15. Regarding the game's direction post-launch, Lead Designer Anthony emphasized that Unknown Worlds is committed to 'Open Development.' He noted that the best results come from developing alongside the players, and that they intend to deliver surprises and fun to users through early access while incorporating their feedback into the development process. With only two days left until the early access launch, all eyes are on whether the game can live up to the reputation of its predecessor, which sold 18.5 million copies.
