It's a bit tidius until you get a couple of water filtration systems and interior grow beds going. Water seems to drain the fastest so just eat on the go with a thermoblade and farm water with the machines. Each water fills up +50 so you only need to drink one to fill up half the gauge. I have like 20 water bottles in the cyclops.

Find plants and invalidate the entire system.

As others have, said, growbeds.

Fish will also breed in an Alien Containment tank, and you can even put growbeds in your Cyclops! Food on the go! The Bulba Trees on the Island make for a good food source to plant and grow I find (they will need indoor growbeds, not exterior ones ofc)

In creative mode the story is disabled. You want to play freedom, which disables food and thirst

Make disenfected water from coral tubes and salt, then find and build a water filtration system along with some growbeds and you will be good. Endless amount of water and food. The thermoblade upgrade also is essential.

Get the locker really quick, you need storage and the floating locker things are not efficient and require a lot of titanium. Bladderfish provide water early on until you can get more complex things to satisfy hydration like melons, water purifiers, and espresso machines. Eventually you'll find the planter which will let you plant your own crops to eat (melons for hydration and even gel sacs for aerogel production) and then you'll find the aquarium which is great for creature breeding and an infinite fish food source.

Water's easy, just grab some salt and a piece of a giant coral tube and you can make bleach, which gives you 2 bottles of water.

Bladder fish for water and peppers for food are close by

Don’t cook fish before you’re ready to eat them. They stay alive indefinitely in your inventory. Cook them only when you’re about to eat them.

And follow the advice on salt + giant coral tubes. Make bleach, but don’t convert it to water until you’re in need of water.

depends how far you are into the game. You eventually get to a point where food and water are so plentiful it's not even an issue.

I’m also a new player and still in survival mode. I don’t like exploring at night so I usually use that time to craft, use the gravtrap to catch fish, and top up on food/water/health.

Spending some time daily (or nightly) collecting food and water supplies early game is essential for sure. I also like collecting slavaged debris when I have spare space because I use alot of titanium. I like making sure my different essential ores are topped up too

I start the game, do nothing, go to the Dunes, mess around, then I losr my P.R.A.W.N for the 200th time. So I reload my last save and repeat.

They only take up 1 slot of inventory, so they are more space-efficient than other plants.

I went out in the seamoth with 5-10 gel sacs, and a couple of water bottles and by the time I ate them all, my inventory was full and it was time to return to my base anyway.

Once I got there, I could get more gel sacs from my farm on a foundation beside the hatch.

Depending on play style, either grow edible crops in bases/Cyclops, or use a grav trap or Alien Containment to farm edible fish and then use the salt produced by your water filtration to preserve them. If you do that, the Reginald (44 food per serving!) is the obvious choice.

I have a growbed of marble melons usually, though 1-2 plant pots of them is enough to sustain you. They also possess enough water content to sustain you on both fronts, I hear bulbo trees are technically better than marble melons now (for both food and water) but idk. For long journeys I always have a population of Reginalds in my alien containment, and you can cure them using the salt gained from water filtration.

Put 2 Reginald in an alien containment unit. They'll breed, and as long as you leave 2, you'll never run out. Use salt from water filtration machine to cure them and they last forever. I like to eat bulbo trees and marblemelons when at my base to fill up, then take cured reginalds with me.

Yeah that's why you stop eating cured fish altogether when at base. Makes a big difference I find I still have plenty of fish.

Nutrient blocks are an excellent recipe idea.

Grow crops, easy to make, and require nothing to keep them going, and you can use crops in the bioreactor for fuel aswell. Way more efficient than fish

I’m excited about the glass ceiling. Will make for awesome creative builds but worry it’ll be hard to have tons of glass in my normal build

Yknow, for a game based 99 percent of you being in the water. You go thirsty ALOT

OP your base is beautiful and as soon as XBOX goes live I can't wait to build my own!

There's a glitch with the coconuts, putting your empty ones back in a pile of drinkable ones refills them and you can only drink 2 every 10 second i think it was

Plant a Yucca if you can. 3 plants can be found on the island and a lot on the beach. They are hard to spot.

Cut down a few palm trees and chop up the palm fronds to use as fuel for the water machine. And build at least 2 for personal use.

Add palm leaves or fibrous leaves to the bottom of the water purifier

I have 3 water stills on my island. After you get a few more supplies, make more stills and you'll never run out of water.

Check on the kitchen and if it is making full meals or "compensated" meals bc it doesn't have enough ingredients. You also may just need more leisure time so they will have time to eat, I kept the default 3h per day but find I occasionally have to override someone starving bc they just haven't eaten.

I'm new to the game so I don't really know, but I think they need a healthy diet, so maybe they need meat? Like, they are not going to die but they are hungry because their diet it's not balanced.

As long as a kitchen has raw food in it like fruit, vegetables, meat etc. in it the crew members should just go and make a meal at the kitchen when they are hungry.

My first thought is gardening. Get some of the fruits from the green house and hunger and thirst are dealt with for the rest of the game.

In the original Subnautica, you can make purified water with bleach (made from salt + coral sample) but that's not in BZ. In BZ, you can make water with snow and the purifier tablets, but you have to find them at an Alterra base first.

Plants

In the original I remember finding a ton of water bottles from exploring wrecks and the Aurora. You'd also find nutrition bricks, but less often.

Without fish, you may need to be a bit meta about it and pursue the water purifier and land plants more aggressively. An easy way to find the land masses before the game tells you where they are is to surface and look for the clouds hiding them. Once you have melons you can just gorge on those.

In the original my base near the mushroom forest was about 100m. This made the 8 solar panels only about 50% efficient during the day. But the 600 power capacity was enough to get it through the night (much shorter than day). Btw, you can check your panel efficiency at any time by hovering your cursor over one.

Deeper down with no light, 4 well placed thermal plants can out pace the water filter, 5 just in case.

And the best solution is to have melons (or still suit, gross). They slow down your water consumption so you can leave the water in the machine so when it fills it shuts off. Then you let the batteries recharge and get the water when the system can handle more drain.

Bioreactor is also good but I hate how much space it takes up and it's an active use, as in you have to keep manually feeding it. Nuclear is also good, except it's also active and (unlike real life) the nuclear fuel wears out too quick. Also it makes a bunch of noise.

Well, yep, water filtration is… pretty greedy for power, as of course is scanning. 65° is a little on the low side for thermal, you might be able to tune it up a bit by resiting one or two, or the ultimate solution: nuclear!

I have a bioreactor and a nuclear reactor as my only power sources, with one scanning room and two water filtration systems. I still haven't encountered power issues yet. My advice: get an alien containment full of Oculus.

I usually just used a ton of solar panels in shallow areas, but with multiple water filtration systems I’d say go nuclear. It’s hard to maintain that much energy any other way.
