If you check the Steam listings for the original Subnautica titles, you'll find the "Survival" tag prominently featured. This is largely due to the intense gathering, crafting, and the constant risk of drowning in a hostile biosphere. However, during an interview with PC Gamer ahead of its upcoming early access launch, developers revealed that Subnultica 2 will prioritize a different core experience.

Prioritizing Exploration Over Survival Mechanics

While Unknown Worlds often refers to the sequel as a survival game in public, the internal design philosophy is different. Subnautica 2 lead gameplay designer Anthony Gallegos explained that the team focuses on the title being an exploration game first. In this framework, the survival mechanics serve to support and drive that exploration.

The developers are using the survival systems as a way to provide structure and momentum as players dive into alien ruins. While maintaining the core loop of the original, the team is also refining the user experience with several quality-of-life improvements:

  • Proximity-based inventory sharing between lockers while crafting.
  • Refined survival systems that elevate the player experience.
  • Improvements inspired by "best in class" features from other modern survival games.

Gallegos noted that the team is looking at the most frustrating elements of the first game and attempting to "elevate those while preserving the crux of things."

New Environmental Dangers in Subnautica 2

While returning players might find the survival systems familiar, creative media producer Scott MacDonald warned that new environmental factors will catch players off guard. One major addition is the introduction of ocean currents.

"We have currents in Subnautica 2, which we didn't have really in Subnautica 1 or Below Zero," MacDonald said. He noted that a player could easily be swept around a corner and taken to an unknown, deeper location without realizing it.

The visual atmosphere is also shifting to create a more palpable sense of dread. Gallegos mentioned that the sequel will feel much darker, closer to the atmospheric tension of the original game rather than Below Zero. With more dynamic lighting and popping bioluminescence, the shift from shallow waters to the deep abyss will feel significantly more threatening.

Encountering New Alien Fauna

The depths of the new world are populated by entirely new alien ocean fauna. Early trailers have already showcased massive squids and giant crabs that look nothing like the creatures from previous games.

This lack of familiarity is a deliberate design choice to ensure players feel a sense of uncertainty. Gallegous stated that if they had used the original planet, players would feel too safe because they already know the ecosystem. In this new world, players are back to square one—unable to tell if a strange sound comes from a friendly creature or a predator.

Emulating a "Masterclass" in Player-Driven Discovery

The development team is drawing heavy inspiration from what Gallegos called a "masterclass" in player-driven discovery: the original Subnautica. The goal is to make players feel clever, as if they are uncovering the world entirely on their own.

Rather than using an explicit on-screen quest log, the developers want to use subtle environmental cues and beacons to guide players. This allows for a personalized experience where no two players play the game exactly the same way. Gallegos noted that even when level designers point players in a specific direction, the sense of freedom remains intact.

Early feedback suggests the team is already hitting their marks. "The best compliment we had when we had some of the early play testers was they were like, 'I feel like I'm returning to Subnautica,'" Gallegos said.

Subnautica 2 is scheduled to launch in early access on Steam on May 14.
