How To Download Subnautica On PC – New Detailed Instructions

If you are a fan of the survival game genre, you must have heard of Subnautica, one of the games that immerses players in a vast and mysterious ocean world. However, the barrier of the English language sometimes makes it difficult for Vietnamese gamers to fully grasp the storyline and gameplay.

That is why the Subnautica was created, helping you to easily experience the game more completely. In this article, I will provide detailed instructions on how to download the Vietnamese-localized Subnautica, how to install it, and how to fix common errors while playing, along with useful tips to start your ocean exploration journey today. The following article will guide you to download Subnautica quickly and conveniently.

What is Subnautica?

Subnautica is one of the most famous underwater survival-adventure games developed by Unknown Worlds Entertainment, first released in 2018. The game quickly gained popularity thanks to its vast open world, vivid graphics, and unique gameplay that drops the player onto a water planet named 4546B.

In the game, you play as an astronaut who suffers an accident and is forced to survive deep beneath the ocean. Players need to dive deep to explore, search for resources, craft tools, build bases, and simultaneously confront giant sea creatures and un-explored mysteries.

The unique features that have attracted millions of players to Subnautica are:

• A vibrant underwater environment with a diverse ecosystem.
• Rich survival and crafting mechanics.
• A mysterious storyline told through the process of exploration.

However, because the game does not officially support the Vietnamese language, many domestic gamers have difficulty clearly understanding the plot or crafting instructions. This is precisely why the Vietnamese localization of Subnautica was created, offering an easier and more complete experience for the Vietnamese gaming community.

System Requirements for Playing Subnautica

Before downloading and installing the Vietnamese localized Subnautica, you need to ensure your computer is powerful enough for a smooth gaming experience. Although it was released a while ago, Subnautica still features realistic 3D graphics and a vast ocean map, so the system requirements are not light. If your PC only meets the minimum specifications, the game will run but may experience stuttering or lag when diving deep or in areas with high detail. For the best experience, you should aim for the recommended configuration.

How to Play Subnautica Correctly as a Survival Game

If you are new to Subnautica, the most important thing is to master the basic survival mechanics. This is an “underwater survival” game, so besides exploring the world, you need to constantly manage resources, health, and oxygen to survive.

Gathering Resources for Crafting

As soon as the game begins, you will be dropped into the ocean with a Lifepod. This is your first safe location.

The first thing to do is swim out to gather resources:

• Titanium: Can be obtained from Metal Salvage.
• Quartz: Used to craft Glass.
• Copper, Lead, Silver: Extracted from small rock deposits (Limestone Outcrop, Sandstone).
• Acid Mushroom & Creepvine Seed Cluster: Used to craft batteries and lubricants.

Resources are then crafted in the Fabricator (the crafting machine inside the Lifepod).

Tip: Always carry at least 2–3 basic materials, as you will need to craft tools like the Oxygen Tank, Fins, and Scanner right from the start.

Crafting Survival Tools

In the first few hours of play, you need to immediately craft several essential tools:

• Scanner: Scans blueprint fragments to unlock new technology.
• Repair Tool: Repairs the Lifepod and broken modules.
• Survival Knife: Basic weapon for self-defense and resource collection.
• Oxygen Tank: Increases oxygen capacity when diving.
• Fins: Helps you swim faster.

This is the “minimum” survival kit that new players need to start their journey.

Managing Oxygen While Diving

Oxygen is the most critical factor when diving. If you run out of oxygen, you will suffocate and die instantly.

• Always keep an eye on the O2 bar in the bottom corner of the screen.
• Initially, you only have 45 seconds of oxygen; craft additional Oxygen Tanks to increase dive time.
• When you hear the “Oxygen” warning, swim to the surface immediately.

Tip: Later, you can craft the Seaglide or Seamoth for faster and safer movement in the deep sea.

Cooking Food and Getting Drinking Water

In Subnautica, you must maintain both Food and Water (H2O) levels:

• Food:
  • Catch small fish species like Bladderfish, Peeper, Boomerang.
  • Use the Fabricator to cook (Cooked) or cure (Cured) them.
  • Tip: Cooked food will lose freshness over time, while cured food lasts longer.
• Water:
  • Use Bladderfish to craft Filtered Water.
  • Later, you can craft a Water Filtration Machine to automatically generate clean water.

Advice: Always carry at least 2 bottles of water and 2 servings of food when venturing out.

Managing Thirst and Hunger

Besides oxygen, you must continuously monitor the two indicators: Food and H2O.

• If you let yourself go too hungry or thirsty for too long, your health will gradually deplete, leading to death.
• It’s better to eat and drink regularly rather than waiting until you are depleted, as preparation is safer when you venture into deep areas.

Exploring and Building a Base

After stabilizing your survival needs, you can start building an underwater base using the Habitat Builder tool.

A base helps you:

• Store resources.
• Craft advanced equipment.
• Serve as a safe resting spot during long expeditions.

Choose a location near resources, with favorable terrain, and not too far from your initial Lifepod.

Notes When Playing Multiplayer in Subnautica

Currently, Subnautica does not have an official multiplayer mode because the developer, Unknown Worlds, only designed the game as a single-player survival experience. However, the player community has created several multiplayer mods (the most popular being the Nitrox Mod) that allow you to experience the game with friends.

However, you need to keep the following in mind:

• Community-Developed Mod: This is only a mod created by the community and is not officially supported by the publisher.
• Frequent Potential for Bugs: You may frequently encounter game errors such as disconnections, synchronization issues, and bugs when building or exploring.
• Incomplete Features: Some mechanics (e.g., storyline elements, cutscenes, animations, etc.) may not work stably.
• Risk of Game Crash: Especially if playing for a long time or on a low-specification computer.

Therefore, view multiplayer only as a fun, experimental experience, and do not expect the stability of official online games.
