The behaviour of gases in the game is modelled to resemble the laws that rule them in real life.

Of course this is still a game, and there are some simplifications.

The game allows you to transform almost any matter into the gaseous state, upon reaching the correct temperature.

The higher the gas concentration, the more intense the “smoke’s” colour.

Gases can be divided into two groups.

The first one isBreathable gas, the gases which your duplicates can inhale.

PC

Of course, this includes oxygen, as well as its contaminated version.

Apart from that, it contains what the duplicates can inhale and still be able to function.

Keep in mind, thatevery substance in the gaseous state is assigned a certain weight.

PC

When there is only one kind, it will strive to fill the entire room.

Unlike real air,there is no such thing as the mixing of gases.

If there are several gases of similar density in one room, they will form layers.

PC

Hydrogen will be located the closest to the ceiling, being the lightest gas.

Next, there is steam, chlorine and the heaviest gas: carbon dioxide.

Keep this in mind when planning your base and designing rooms.

PC

It is worth to have, e.g.

a small basement, where carbon dioxide will be able to calmly descend, without poisoning the main rooms.

It is a light gas and will rise above most other gases.

PC

It has a bluish glow.

It can be obtained in an artificial way by using machines and other resources.

Polluted Oxygen

Contaminated Oxygen.

Oxygen Not Included

A light gas that will usually float on an equal level to pure oxygen or right below it.

It has a colour of rotten bile.It is still breathable by your people.

However,exposure will lead to illness, so you will want to minimize its quantity in the base.

Naturally, it’s possible for you to encounter it in large numbers in the toxic biome.

It is most often extracted from contaminated dirt or water.

It is also produced by Morbs and by duplicates, who have the trait “Flatulence”.

Carbon Dioxide (CO2)

Carbon Dioxide.

It is theby-product of inhaling oxygen by the duplicates.It is a waste and is not suitable for inhaling.

It has a black shade and looks like dark smoke.

I does not occur naturally.

It is the heaviest gas and will drop to the lowest levels of your base.

It is worth building an extra room where you will gather it.

There, you could remove it in several ways, e.g.

by processing it using an algae terrarium.

Hydrogen (H2)

Hydrogen.The lightest gas, which will rise above all others.

It has a pink colour andis unsuitable for breathing.

It occurs naturally in the Purple biome.

it’s possible for you to create it as one of the products of the hydrogen generator.

It is suitable for industrial purposes, such as the production of electricity in a relevant machine.

Chlorine (Cl2)

Chlorine.An extremely toxic gas.Not applicable in industry.

It often causes illness.

You will usually encounter it in the Purple biome.

The unique resource - Bleach Stone, emits it.

near the bottom of the map.

Sometimes, you may encounter steam geysers on the map.

Usually there will be several similar objects in the game world, typically in the green biome.

Thay will periodically generate a certain volume of steam, which will quickly turn into liqid.

This will enable you to replenish your water reserves.

Natural gas, Natural gas gyser.

Natural gas - a flammable, unbreathable gas.

You’ll find it only near its dedicated geysers.

It’s got a significant volume density, usually around 5kg per field.

It can be used in your industry as a power source.

By pumping it into aNatural Gas Generator, you’ll be able to produce significant volumes of power.

There are usually only few such geysers on a map, typically between 1 and 5.

Vacuum, The Void

Vacuum.

It is not a gas, but rather the lack of gas.

It has no colour, unlike how it is in the case of gases.

Duplicates will hold their breath in such an environment.

Thus, the vacuum will disappear.

The Void.It is not gas, but rather an unknown object that has special properties.

This is a naturally occurring phenomenon.

With one distinct difference,it only sucks in all of the nearby gases.

It is a soft mineral that can be mined by every duplicant.

It has filtering properties - you might use it in Water Sleve to filter Polluted Water into normal water.

After adding sand you will receive Polluted Dirt.

If you heat up the Regolith to the temperature of 1410 degrees, you will receive Magma.
