Food and Water: From Starter Supplies to Long Trips
Updated
Use the Lifepod's starter food while establishing a Water Slug supply, then unlock Digestion to make local food useful. Before a long trip, plan food and drinking water separately: filling the hunger meter does not ensure you have enough hydration for the journey home.
Opening survival loop
- Open the starting supply locker. The first-hour walkthrough shows three Nutrient Blocks and an Aid Kit. Each block restores 40 food; eat according to the hunger you need to restore rather than consuming them all at departure.
- Catch a Water Slug and return to the Fabricator. One Water Slug makes one Water. The illustrated starter route shows this restoring 40 water, making it a practical first hydration loop.
- Follow NOA's Anita black-box lead to the Angel Comb. Interact with the central pod to unlock Digestion. Confirm it in the PDA's Adaptations tab before treating local flora and fauna as your main food supply.
- Prepare local food back at the Fabricator. Catch fish during short gathering loops, craft the corresponding cooked food, and leave with both food and water replenished.
If eating local food still leaves you struggling with digestive incompatibility, check the adaptation first. Collecting more of the same fish does not complete the Angel Comb interaction. Keep some starter food available while you finish that route.
Compare the supply recipes
| Supply | Ingredients per craft | When it fits the trip |
|---|---|---|
| Water | 1 Water Slug at the Fabricator | Opening hydration with a simple collection loop. |
| Water from Fibrous Pulp | 3 Fibrous Pulp at the Processor | An alternative when plant material is plentiful. |
| Isotonic Water | 1 Flash Slug + 1 Salt | A crafted drink when you have both ingredients available. |
| Cooked Halfmoon or Cooked Geordie | 1 matching raw fish | A straightforward cooked-food loop after Digestion. |
| Nutrient Block | 1 Biofuel Block + 1 Salt | Make additional rations once the processing chain is established. |
Other fish also have their own cooked recipes, including Bluemoon, Harvestmoon, Quadrate, Electric Geordie, Hoverthorn and Blackthorn. Compare the food and water effects shown on the item you are about to consume. A food with a hydration penalty needs a separate drink in your packing plan; do not assume every cooked or raw fish has the same values.
Reserve Salt before processing supplies
Salt from Chap's cave serves several competing recipes. One Power Cell uses 1 Salt, one Isotonic Water uses 1 Salt, and one Nutrient Block uses 1 Salt. Preparing one of each means collecting 3 Salt, plus their other ingredients.
If your immediate goal is a Tadpole, reserve its Power Cell ingredient before making a batch of drinks or rations. Plain Water from Water Slugs does not use Salt, so it can cover hydration while your small early Salt haul goes toward vehicle power.
Halfmoons also have an industrial use: the Processor turns two into Grease. Set aside enough food before allocating fish to equipment materials. Likewise, check your base's fuel supply before turning every Biofuel Block into a ration.
Use Biomods for water resupply
Water Secretion is useful when the problem is finding another drink. In PC build 131439, it creates a Filtered Water Packet and increases its base water value in 5-point steps every 2 minutes 30 seconds, up to 30. Starting without a packet, uninterrupted filling takes 15 minutes from equipping to reach that full amount. Bring a ready drink for the early part of a trip.
Keep a partial packet in your backpack while it fills. Once it reaches 30, use it or move it into storage so a later cycle can start another. Leaving the full packet in your backpack does not keep building a reserve of additional full packets. See the water-packet timing table for each stage.
Water Retention solves a different supply problem: it doubles positive hydration from food and drinks in this build. It does not slow passive thirst drain. With two unlocked passive slots, pair it with Secretion to turn a full 30-water packet into a 60-water refill, subject to your water limit. Otherwise, choose the ability that best fits the supplies you already have.
Water Slug bioscans contribute to Secretion research; Coral Crab research unlocks Retention. Secretion is also offered by a later Biolab, so check your unlocked abilities before planning a special trip. Use the passive-slot milestones to plan when you can equip both.
Pack for the route you are actually taking
- Short material loop: top up before leaving, collect the required material and return to the same crafting point. Do not wait until thirst is critical to begin looking for a Water Slug.
- New wreck or cave: carry food and water for the return leg as well as the outward journey. Leave room for the objective, and separate oxygen planning from meal planning.
- Moving to the Research Station: take ready supplies before starting the Alien Ruins route. Restoring a new station and finding ingredients there can take longer than a familiar gathering loop.
- Regular base excursions: keep a small prepared reserve and replace it after each trip. A restock habit is easier to maintain than an emergency search each time a meter runs low.
Keep edible supplies out of the fuel pile
The Buddy System update fixed Algae Blocks and Nutrient Blocks being unusable as Bioreactor fuel. This makes food storage and fuel storage worth separating: an edible ration can become base fuel when you still need it for an expedition.
For a longer-term supply routine, connect growing food and useful plants with your Bioreactor fuel plan. Keep the next trip's ready meals and water reserved before spending the surplus on processing or power.
