In Subnautica 2, resources, materials and food are the everyday supplies you collect, craft and eat to keep going. Raw resources like Copper, Silver and Quartz come from caves and the seabed, and the Fabricator and Processor turn them into the parts you need. Food and drink come from the fish, slugs and plants around you, and each group has a clear job in keeping you alive and your gear working.

How Resources, Materials and Food Work Together
Raw resources are what you find out in the world, like Titanium, Lead and Pent. Materials are what you make from them, and they often feed each other. Copper can become Copper Wire, which goes into a Wiring Kit with Silver, and that kit can become part of a System Chip. Once you see how one item leads to the next, it's easier to know what to bring home.
Biological pickups sit in the middle of this. They are parts you harvest from creatures and plants, like Acidic Raion Pouches, Fibrous Pulp and Necrolei Cysts, and they go into recipes just like raw resources do. Food and drink run alongside, though a few ingredients, like Salt, serve both crafting and cooking.
Most crafts need pieces from more than one place, so it helps to think in chains. When you head out, work out which ingredient is hardest to find and go after that first. Then collect the easier pieces on the way back, so you don't end up with half a recipe.
How to Gather Resources and Biological Pickups
Most raw resources are loose pieces you find by searching, so exploring is part of the job. Check cave roofs, overhangs and shadowed crevices for Copper, look through shallow coral, caves and the seabed near the start for Quartz, and follow the starter routes for Titanium. Many early finds sit near the starting area, so you can build up a stock there before pushing deeper.
Biological pickups need harvesting, and the Survival Multitool is the tool for it. Acidic Raion Pouches come from creatures in the caves below the Lifepod, while Fibrous Pulp comes from the plants along your first route. Some parts only come out after you've dealt with something else, like the Medical Gel Sac in the middle of an Acidic Raion once its pouches are gone.
Some minerals sit in deposits that need a Sonic Resonator to collect, including Atacamite, Conduit Crystal and Creature Enamel. Bring one before you head into those areas. The deepest materials, such as Troilite and Axum Bacterial Culture, lie beyond the Alien Ruins, so plan those trips once your supplies are ready.
How the Fabricator and Processor Turn Materials Into Parts
Most crafting happens at the Fabricator, which makes things like Copper Wire, Glass, Basic Batteries and cooked meals. The Processor handles refining. It turns raw metals into ingots, which are refined metal pieces, and it makes a few special parts such as Plasteel Ingots, Grease and Biofuel Blocks.
Processing can also stretch your raw stock. A Titanium Ingot takes less Titanium at the Processor than at the Fabricator, so the Processor is the better choice when Titanium runs short. Silver and Gold Ingots each take three raw pieces of their metal at the Processor.
Some parts can be made in more than one way, so you can use whichever fits what you're carrying. Strong Acid comes from two Necrolei Cysts at the Fabricator, or from one Sulfur and one Gold at the Processor. Biofuel Blocks can be processed from Fibrous Pulp, Pents or Crab Feces, so whichever one you can gather most easily will do.
Which Early Resources Matter Most
Silver and Copper are the tightest materials early on. Silver goes into Standard Air Tanks and Wiring Kits, and it's one of the main limits on oxygen upgrades. Copper runs through early wiring and power, and it's part of the Mild Acid you need to build the Processor.
Quartz and Titanium come up again and again. Quartz makes Glass and System Chips, so keep some back for scanning and base recipes rather than spending it all at once. Titanium is the general construction stock, and it also feeds Titanium Ingots and Plasteel Ingots.
Salt, Sulfur and Lead are easy to overlook, but they turn up in important places. Salt is shared across power, drinks and food, so it's worth keeping a stock. Sulfur helps with the Repair Tool, and Lead's first two pieces are best set aside for the Sonic Resonator. Gold has to wait until you unlock Heat Tolerance, and Troilite comes from deeper areas, so both belong to later progress.
How to Make Advanced Batteries and Entangled Power Cells
Power starts simple. A Basic Battery comes from two Copper and an Acidic Raion Pouch, and a Power Cell builds on two Basic Batteries with Strong Acid and Salt to store power for vehicles and base systems. Advanced Batteries and Entangled Power Cells are the higher-capacity options, useful when recharging keeps breaking up your exploring.
Both upgrades need a Conduit Crystal and a Strong Acid, and each needs two scans to unlock its blueprint before the Fabricator will make it. An Advanced Battery adds a Silver Ingot, while an Entangled Power Cell adds a Gold Ingot and a Troilite. Neither one uses up your regular Basic Batteries or Power Cells, so you can keep a spare while you work on the upgrade.
They belong to different families, so check the device first. Advanced Batteries suit compatible tools, and Entangled Power Cells suit compatible vehicles, so a bigger cell won't always fit a handheld slot. Because both draw on the same Conduit Crystal and Strong Acid, decide which upgrade you need next and set those pieces aside for it.
Food and Water: What to Eat and Drink
Food and water are separate meters, so a full stomach doesn't mean you're hydrated. Your starter locker has Nutrient Blocks, which are ready to eat. For water, catch a Water Slug and turn it into Water at the Fabricator, which gives you your first reliable drink.
Local food becomes useful once you unlock Digestion, which is what makes the fish and slugs you catch worth eating. Many fish can be eaten raw, but raw fish carry a dehydration penalty, so cook them at the Fabricator when you can. Halfmoons, Geordies and Hoverthorns are among the fish with their own cooked meals, and Oily Salad is the plant-based option made from Fibrous Pulp.
For a crafted drink, Isotonic Water combines a Flash Slug with Salt at the Fabricator. The Water Secretion Biomod also slowly fills a Filtered Water Packet while you explore.
Planning Food, Water and Materials for Longer Trips
Food and materials share a few ingredients, so decide what you're using them for before you spend them. Two Halfmoons make Grease at the Processor, so set aside enough fish to eat before you turn any into equipment materials. Biofuel Blocks can fuel a bioreactor, but one can also be combined with Salt to make a Nutrient Block, so know which job it's doing first.
Before a longer trip, pack food and water for the way back as well as the way out. Top up before you leave rather than waiting until thirst is urgent, and keep a small ready reserve at base so you aren't looking for a Water Slug in a hurry. Set aside the next trip's rations and water before spending any surplus on processing or power.
FAQ
How do I unlock Digestion in Subnautica 2?
You unlock Digestion at the Angel Comb. Follow NOA's Anita black-box lead to the Angel Comb, interact with the central pod, then confirm it in the Adaptations tab of your PDA. Catching more of the same fish won't complete that step, so keep some starter food on hand until you've finished it.
How do I get more water from a Filtered Water Packet?
Pair Water Secretion with Water Retention once you have two passive slots unlocked. Retention doubles the positive hydration you get from food and drinks, so a full packet goes twice as far, as long as it fits under your water limit. Retention doesn't slow your passive thirst drain, so if you only have one slot, choose the ability that fits your supplies best.
Can I use Nutrient Blocks as fuel?
Yes. Nutrient Blocks can be burned as bioreactor fuel, so an edible ration can end up as fuel if you're not careful. Keep your trip rations separate from the fuel you feed your base.
How do I recharge an Advanced Battery?
Build a Battery Terminal or Power Cell Terminal at a powered base, then place the supply in the slot that accepts it. Watch the charge rise before you leave it unattended. The terminal only moves energy your base already has, so if the base keeps running dry, address generation and consumption rather than crafting more batteries.
