What is the primary source of breathable air when diving early in Subnautica?
Survival Knife
Standard O2 Tank
Fabricator
Handheld Scanner
The Standard O2 Tank is your primary source of oxygen underwater, extending your base supply and allowing for longer dives. The handheld scanner is used for data collection, the survival knife for cutting, and the fabricator for crafting. Without upgrading your O2 supply, you'll have a very limited time underwater. For more details, see the O2 Tank page on the Subnautica wiki:
Which tool is required to repair damaged equipment and base modules?
Propulsion Cannon
Repair Tool
Welder
Stasis Rifle
The Repair Tool is used to fix damaged equipment, vehicle parts, and base modules. The welder is not an item in Subnautica, while the stasis rifle and propulsion cannon serve entirely different functions. Keeping your gear and base intact is crucial for survival. You can find more information here:
What raw material is needed to craft Glass in the Fabricator?
Sand
Salt
Silver
Quartz
Glass in Subnautica is crafted from Quartz, which is abundant in the early game. Sand is not a collectible resource, silver is used for electronics, and salt is consumed for food. Glass is crucial for creating windows and observatories. Read more at:

The Scanner is the handheld device designed to digitize fragment blueprints and marine life data. The Seaglide and fins are mobility tools, while the Repair Tool is for fixing equipment. Scanning is essential to unlock new blueprints and entries in your PDA. For detailed usage, visit:
Which materials are required to construct the Mobile Vehicle Bay?
1 Lead, 1 Wiring Kit, 2 Titanium Ingots
3 Copper, 1 Advanced Wiring Kit, 1 Gold
2 Titanium, 2 Silicone Rubber, 1 Wiring Kit
2 Silver, 1 Battery, 1 Glass
The Mobile Vehicle Bay requires 2 Titanium, 2 Silicone Rubber, and 1 Wiring Kit to fabricate. Titanium is mined from deposits, while Silicone Rubber comes from Creepvine samples. The wiring kit is crafted from table coral sample and gold. For full blueprint details see:
What is the base depth rating of the Seamoth without any depth modules?
300 meters
150 meters
200 meters
100 meters
The Seamoth has a default depth rating of 200 meters before hull integrity starts to degrade. Upgrading with depth modules increases this limit. A 150 meter or 300 meter rating does not reflect the stock capabilities. More on vehicle stats:
Which ingredient is NOT used in the crafting recipe for Lubricant?
Creepvine Sample
Rubber
Gel Sack
Jellyray Sample
Lubricant is crafted from Creepvine Samples and Gel Sacks in the Fabricator. Jellyray Samples are not part of any recipe and Rubber is a component of Silicone Rubber. Knowing crafting recipes is crucial for late-game vehicles. View recipe details here:
Which resource requires a Laser Cutter to harvest it from its outcrop?
Diamond
Quartz
Copper
Titanium
Diamond deposits can only be extracted using the Laser Cutter tool. Quartz and titanium outcrops can be mined with the survival knife or bare hands, and copper is not found natively in Subnautica. Laser Cutter is essential for high-end resources. See more at:
In which biome are Thermal Spires primarily located?
Kelp Forest
Lava Lakes
Thermal Spires
Abyss
Thermal Spires are a distinct biome characterized by underwater volcanic vents. They are not in the Lava Lakes or Kelp Forest biomes, and the Abyss is farther down. Thermal Spires provide valuable resources like Thermal Plant Samples. More details:
What depth range around the Aurora is contaminated by radiation without a Radiation Suit?
300 - 350 meters
200 - 250 meters
400 - 450 meters
100 - 150 meters
The area surrounding the crashed Aurora between 300 and 350 meters is radioactive until you obtain a Radiation Suit and Gloves. Above 300 meters you are safe, while deeper zones are unaffected by Aurora radiation. The Radiation Suit allows safe passage. Learn more here:
Which upgrade increases your oxygen capacity by approximately 90 seconds?
O2 Tank Mk II
Seamoth Depth Module
Rebreather
O2 Tank Mk I
The O2 Tank Mk II upgrade adds around 90 seconds of additional oxygen supply. The Mk I adds less, while the Rebreather reduces oxygen consumption but doesn't add that much time. Depth modules affect hull integrity, not oxygen. Additional details:
Where is the Sea Emperor Leviathan's egg chamber located?
Underneath the Floating Island
At the Mountain Island Apex
Primary Containment Facility in the Jellyshroom Caves
Inside the Deep Grand Reef Crash Zone
The Sea Emperor's egg chamber is in the Primary Containment Facility located in the Jellyshroom Caves biome. Other locations like the Floating Island or Deep Grand Reef do not contain the egg chamber. Discovering this area is critical to the story. More at:
Which resource is needed to craft a High Capacity Battery?
Gold
Lithium
Ruby
Diamond
A High Capacity Battery requires a standard battery and a Ruby in the Fabricator. Diamonds are used in high-end tools but not in this recipe, and lithium and gold serve other crafting purposes. High Capacity Batteries improve power storage significantly. Check the details here:
What is the maximum depth rating of the Prawn Suit equipped with a Mark III Depth Module?
1000 meters
900 meters
1500 meters
1200 meters
The Prawn Suit's base crush depth is about 700 meters, and each Mark III Depth Module adds an extra 500 meters. Equipping a single Mark III brings the total to 1200 meters. This is essential for exploring deep biomes like the Abyss. See module specs:

Cheat Sheet

  1. Biome Depth Ranges -

    Memorize each biome's safe depth - Safe Shallows (0 - 80 m), Kelp Forest (50 - 130 m), and Grand Reef (50 - 200 m) - to ace Subnautica trivia on navigation. Use the mnemonic "SKG" for Shallows, Kelp, Grand Reef. Official Subnautica wiki depth charts confirm these ranges help you locate resources and dodge hidden dangers.

  2. Alien Fauna Identification -

    Learn to recognize key creatures like Stalkers (30 - 100 m), Reefbacks (50 - 300 m), and Ghost Leviathans (200 - 900 m) for top scores in your Subnautica quiz. A handy trick: "S R G" spells "Scary Real Ghosts" to recall their threat levels. The Unknown Worlds Entertainment bestiary offers detailed behavior profiles that improve your survival odds.

  3. Crafting Power Management -

    Understand that each fabricator uses a base 7 W plus 2 W per item to calculate total power draw when planning your moonpool or base. The formula P_total = 7 W + (2 W × item count) will help you breeze through Subnautica game quiz crafting questions. Official dev blogs emphasize that balancing power prevents system overloads during deep dives.

  4. Seamoth Upgrade Tiers -

    Memorize Depth Module ratings - Mark I (100 m), II (200 m), III (900 m) - so you can answer any Subnautica questions about vehicle upgrades. Think "1 - 2 - 9" for a quick mental map of your maximum dive limits. The Subnautica Technical Manual lists upgrade locations and blueprint fragments for each module.

  5. Wreck Sites & Fragment Hunting -

    Key wreck coordinates (e.g., Aurora Engine Room at 23°S 145°E) yield vital blueprints for advanced gear and base components. Use the "Three Twenties" rule: 23°S, 145°E, 210 m depth to lock onto Aurora fragments fast. Official beacon logs and the Subnautica wiki ensure you'll never miss a life-saving blueprint during exploration.
