I'm sure you've experienced it: that sinking feeling in your stomach when you look at a very dark sea, or the unease that arises when you think about what lurks in the abyss. Thalassophobia , which is basically the fear of the deep sea or vast bodies of water, is much more common than we think, and sometimes we don't even know we have it until we're confronted with it.
Interestingly, thousands of people are using Subnautica and its sequel to combat this fear. It's not an official medical treatment, but rather a kind of at-home therapy where the player plunges into an alien ocean to tame their anxieties in an environment where, ultimately, they have complete control over the situation.
The science behind fear in video games
What happens while playing Subnautica 2 is very similar to what psychologists call systematic desensitization . This technique, devised by Joseph Wolpe decades ago, involves gradually exposing yourself to the stimulus that frightens you so that your brain understands there is no real danger. In the game, this happens naturally: you start in calm waters and, as you need resources, you are forced to descend into darker , deeper biomes.
The big difference from a clinic is that here you're in charge. If panic overwhelms you, you can activate creative mode to remove aggressive creatures and focus solely on managing darkness and depth. This granular control is key to stopping the nervous system from triggering alarm signals and allowing the player to progress without getting stuck.
A catalog of underwater phobias
Although the developers of Unknown Worlds didn't set out to make a horror game per se, they realized they had struck a chord. The title is a magnet for primal fears that make you jump out of your seat. For example, megalohydrothalassophobia is triggered when you encounter colossal creatures or gigantic structures that make you feel like an ant in water, perfectly fitting into the list of the most atmospheric open-world games.
But it's not just about size. The game plays on other very specific phobias:
- SubmechanophobiaThat revulsion that sunken artificial objects, such as shipwrecks or abandoned bases, give.
- AcrophobiaYes, the fear of heights also occurs underwater when the ground suddenly disappears and you feel that You are falling into the void.
- Nyctophobia and ClaustrophobiaThe terror of the total darkness of the pits and the anguish of diving through narrow caves where oxygen begins to run out.
All of this converges on the fear of the unknown . The feeling that there's always something beyond that you haven't seen is what keeps the adrenaline pumping and makes the experience as addictive as it is terrifying.
Survival mechanics and depth
To survive in this environment, technology management is vital. Many players obsessively analyze depth modules to prevent their vehicles from imploding. For example, there's a constant comparison between the Seamoth and the Tadpole; while the former has stricter limits, the Tadpole offers greater initial resistance and, in its final upgrades, reaches 800 meters, surpassing the 500 meters of the standard Seamoth model.
This need to upgrade equipment isn't just a gameplay mechanic, but a narrative engine . The game pushes you to descend to advance the story, forcing you to confront your fears in measured doses. It's an architecture designed so that curiosity triumphs over fear, allowing many players to even become interested in real-world diving after conquering the virtual one.
The success of Subnautica 2 lies in its transformation of terror into a source of stimulation akin to a roller coaster. By combining the security of a controller with the gradual exposure to the abyss , the game has become an accidental space of mental well-being where fiction allows one to practice bravery in a place where failure is guaranteed.
