Idea: The first element of survival is the Oxygen mechanics. Carbon. Nitrogen.

1) The character now needs oxygen.
2) The planet may or may not have oxygen in the atmosphere.
There are atmospheres with different oxygen content. If oxygen
in the atmosphere less than 7%, then the character begins to lose life.
3) The character loses life with an open helmet - from the last paragraph.
The helmet can be opened and closed. While the usual
unisex head.
4) If a character opens a helmet in open space, then he instantly
dies.
5) At different altitudes of the planet - the oxygen content is different.
6) There is no oxygen under water.
7) The character has a portable oxygen tank, it stores inside
oxygen yourself. This balloon is activated when the character lowers the helmet.
And it turns off when the character raises the helmet and the circle is full of oxygen.
? Static oxygen cylinder. There are options XS, S, M, L. Installed
to bases or ships. They contain much more oxygen.
9) If the base or ship has a hole between the "street / space" and the inner
the room, then oxygen will escape there and decrease inside the room.
10) An oxygen ingot or oxygen gas (lower concentration) can be loaded into the tank.
11) Oxygen can be obtained using the "Hydroponics" building. Hydroponics
needs to be connected to a tank or container via a "link". Hydroponics needs to be placed
plants (1-2 varieties are available at first). Plants produce seeds after growing.
Basic plants can be found in nature - pick gently with your hand to take it later
and plant them in Hydroponics. Hydroponics will require electricity in the future
for the operation of ultraviolet lamps, as well as water for irrigation and fertilization (since the earth
will be depleted).
12) Alternative structure for oxygen production (in case the world is deserted
and there is no vegetation nearby). Gas splitter. What is he doing? It splits
atmospheric gases and stores them. Those. extracts an ingot of oxygen and hydrogen from the air.
But you need to be careful with him, because during its operation, data is taken from the atmosphere
gases - and the planet has a limited resource of these gases. In the future, his
can be replenished by planting trees or the same Hydroponics in the open
the room.
13) Reversible Ozone Ingot. What it is? From it you can get 1.5 oxygen ingots.
Made in the Chemical Industry.
14) The special skill of the character "breathing technique" allows you to save consumption
oxygen.
15) Stasis chamber (as in the movie "Aliens"). The character can lie in it while the ship is flying.
In Stasis mode, the character does not consume oxygen, but skills in this mode also
are not studied!
16) If there is a lot of oxygen in the atmosphere (more than needed), then the character receives "oxygen
burn ", which also takes lives.
17) Under water with an open helmet, a special scale appears in the HUD, the breath holding scale.
It gradually decreases while the character is underwater. Initially, it is 1 minute.
A character through a skill can develop it up to 5 or even 10 minutes. When the character moves, then
he spends this scale faster. When the scale reaches 0 seconds, an animation occurs - from the mouth
the character comes out with a lot of bubbles and he dies.
18) When the scale from the last point is close to 15-10%, then the sound of "strong tapping
heart. "The same thing happens with a closed helmet when in a portable oxygen tank
there is little oxygen left. Red marks also appear on the peripheral vision, and in the eyes
darkens.
19) When the character opens the helmet in an oxygen-free environment, the exit animation goes
oxygen from the helmet. The same happens when a hole opens in a ship or base.
outside, there is also an animation of oxygen leak.
20) The gas splitter also extracts carbon from the atmosphere.
21) Ships during flight in the atmosphere emit a little carbon (from Nitron fuel), so
thereby replenishing the total carbon in the atmosphere.
22) A high carbon content in the atmosphere leads to the death of a character, as well as too
small content. The same goes for Nitrogen.

23) Plants release carbon into the atmosphere like garbage.
24) Nitrogen can be used to make fuel. Nitrogen can be mined through Gas
splitter. In the future, from waste plants, as well as from sand. Nitrogen is the same
can be used for the manufacture of ammonia in the future (for refrigeration units).
Still to mine in the gas giants.

25) Nitrogen can also be used to produce fuel.

26) Sealed corridor with 2 doors (compartment). It's built as the only way to leave

building / ship to the street where there is no oxygen. This building has its own oxygen tank.

Does not need replenishment. oxygen is supplied when all doors are closed. And this

evacuated when the exit door is open. This compartment will allow you not to waste oxygen.

from a building or ship. If the player puts ordinary doors, then oxygen leaves through them. They are

not completely sealed. There are different sizes of compartments for larger

may enter or even small cars (largest compartments).

NQ have stated they will not introduce a survival aspect...

Apparantly because we are so far in the future, and our clones are self-sustainable in their all nutritous, waste, breathable suits - It's not needed...

Yet, we don't have the technology for rotating parts, vtol engines, 3d scanners...

I dunno what to say, a survival aspect would be cool...

If I'm not mistaken, the developers said that they will not introduce survival yet. want to focus on something else. After release, maybe.
About technology. It seems to me that humanity is too highly developed, just with the technologies that they have now, it would be possible to stop the penetration of a star into the system, and not fly away to save it. Those. I wouldn't absolve the technology in the game. Yes, let's say a suit can collect oxygen from the atmosphere, but a suit cannot take oxygen from vacuum, a suit cannot create matter "from nothing." Even the same energy will be injected in order to extract it. Technologies are not advanced enough to extract energy from "nothing".
Therefore, it seems to me (maybe I'm wrong) that the elements of survival will be introduced, maybe not much, but to some extent they will. And it would be exciting when you need to monitor not only the fuel level, but also, for example, oxygen. But just the need for food and sleep is superfluous for me, otherwise it will start to take too much time. But sometimes filling an oxygen cylinder is still normal.
