Oxygen Not Included is a challenging yet fun game where oxygen is not included. So what does our game mean to us when we say that oxygen is not included? Oxygen Not Included is a game of building a base, managing a colony, issuing orders to the nation and getting angry at the artificial intelligence. In our game, we manage a colony of oppression humans sent from the exploding world to huge meteorites in space. Many factors such as oxygen, heat, hunger in the game aim to make us cry. Let's take a closer look at this game from Klei Entertainment.

When our game starts, we are asked to choose a meteor type and three duplicants to start. Duplicants are human-like clones. Each duplicant has its own characteristics, advantages and disadvantages. For example, a duplicant can suddenly fall asleep in the middle of the day while being strong. We give jobs to our duplicants according to these features, but it would be better if I write about this later.

If I give a brief advice:

You have to carefully examine the 3 duplicants you will choose at the beginning. First of all, be sure to choose those who are enthusiastic about dig, cook and build. At the same time, among the bad features are to be sure: narcoleptic, mouth breather, loud sleeper, anemic, flatulent. Apart from that, if you say that you want to advance in the science tree as soon as possible. You can choose a duplicant with high research feature.

When you start the game, you don't have a problem with oxygen, your surroundings will be filled with that relaxing light blue color. However, your first job should be to make the Oxygen Diffuser, which will allow you to produce oxygen from algae, because as your duplicants breathe, they will consume oxygen, increasing carbon dioxide naturally. And of course, collect every algae you see. Since Oxygen Diffuser will be insufficient after a point, you will benefit from Electrolyzers that will help you generate electricity from water. These turn water into oxygen and hydrogen, and if you find a water geyser, you can use it in an endless loop. You can also generate electricity from the hydrogen that will accumulate.

The most important thing to note about gases at the beginning of the game is that carbon dioxide collapses and accumulates below, and you need to create open spaces for the oxygen to diffuse. If your base is too cramped, the oxygen cannot be distributed in a healthy way. I mean, make spacious rooms, spacious areas. Dig down to get the carbon dioxide down too, and of course don't build rooms there where your clones will need to go often.

Apart from oxygen, there is natural gas that looks orange, hydrogen that looks pink and chlorine that looks green. It's essential that you prevent them from entering your base, because none of them are respirable, you'll appreciate... Hydrogen is going to the top of the map, it doesn't fully diffuse into your base, but chlorine and natural gas always seep in as the doors open, no matter how many airlock doors you make.

Therefore, if these gases are dense near your base, I definitely recommend you to make a water lock. If you search for "liquid lock" on the game's google, you can see examples. Also, there is often dirty oxygen that looks yellow, it can happen inside your base, because there are many factors that pollute the air. But I will cover this in the diseases section.

The most important thing you need to pay attention to after oxygen is your food stocks. When you start the game, you will have enough ready meals to take you for a while. But you need to start your own food production as soon as possible. Therefore, your first researches should be "Basic Farming" and "Meal Preparation".

You can also leave the plants as they are in nature, so they don't need water, fertilizer, etc. They don't want to, but you have to consider that they grow much slower that way. The simplest dish is meal lice produced from mealwood. I also recommend planting mushrooms in areas with carbon dioxide accumulating in a short time.

Let me just point out at this point, if you store food in carbon dioxide-dense areas, it will remain sterile so you don't have to power through refrigerators. Bristle Blossom is also a dish your clones love better, but it requires both water and light.

Apart from that, there are sleat wheat and hot-loving pincha pepper growing in the ice biome, of course you can grow them as they evolve. The plants you grow can also be eaten raw, but of course your clones don't like that, so it's important to start with a clone with good cooking skills. If you have nothing left to eat, you can also make a terrible meal of only water and soil with Microbe Musher, of course, think how happy your clones will be.

Also, check your food stock before buying a new clone, if you produce less food, one more sore will only cause you trouble. Oh, and of course, your clones are not vegetarian, it is also possible to barbecue with the meat of the creatures around. But I'll talk about it in the livestock section.

Water is one of the most important resources.

Needed for food, research and cleaning. Although Terra has plenty of water, it's not an endless source unless you find geysers. There are several ways to save water. The first is to make the toilet and shower as late as possible and make sure that the clones are satisfied with the primitive toilet.

The second saving method is to convert the used water into clean water with Water Sieve. When you use your showers and toilets in this way, you don't waste any clean water unless the pipes are clogged. In addition, if you have run out of clean water sources, it is possible to convert the surrounding sewage pools into clean water with the same method. The only problem is that the microbes in the dirty water do not die completely with the purification method, so you should not use the water you purified in your meals. If you are very desperate, it is also possible to get water by melting the ice, but of course, it is extremely difficult.

So how do we get the power to run the devices we need?

At the beginning of the game, a manual generator is sufficient to use your clones as hamsters, but as you develop, you will have to build machines that require more power. In this sense, the "coal generator" that produces electricity from coal will take you for a long time, because you will find plenty of coal around you. But of course, coal will run out at some point.

Hydrogen, natural gas, oil, steam and sunlight are among the sources you can generate power. But I want to look more at cables and batteries here. There are 4 types of cables in the game, each one stronger than the other:

- In general, the standard cable (wire) you will use can handle a maximum of 1000 watts (1 kw), the cables begin to be damaged in more. At this point, the thing you need to pay attention to is to establish separate electricity networks not exceeding 1 kW.
- If you want make the most powerful generator, still the standard cable will carry no more than 1 kW. Of course, there are cables carrying up to 20 kW, but you cannot use them in your base, because they look too ugly and destroy the whole decor score, and these cables require machined metal, which are materials that take a long time and effort to produce.

So how will you provide sufficient electricity to your base with standard cables that can carry a maximum of 1 kW? This is where the "Power Transformer" comes into play. These accumulate electricity from the generator. You can connect more than one converter to a generator, so it is possible to create different cable networks from a single generator. Of course, the trick is to install all these structures away from your base. Because they look ugly and produce a lot of heat.

In general, the template looks like this: Generator / Smart Battery / Heavy Watt Wire / Power Transformer / Wire

We figured everything out, but why are the plants dying? Could it be heat? Exactly, let's take a look at heat management.

Your duplicants feel bad in too cold and too hot, so you need to constantly pay attention to the temperature situation in your base. As soon as you start the game, first of all, take a look around with the heat indicator. There will definitely be a hot biome nearby. You have to decide in which direction to expand accordingly.

Also, for example, if you have a hot biome on your left, cover it with an "insulated tile" or the heat will slowly seep towards your base. Insulated tile is an amazing thing that prevents heat transfer. So use it often. In addition, the machines in your base (especially generators and batteries) will also heat the area over time, so I recommend that you build the machines that will emit heat in a separate place and close them with insulated tiles.

Especially if the places where you grow plants start to heat up, it becomes a big problem, because plants can live in a certain temperature range. In this sense, you need to plant the plants in places where it is unlikely to warm up, paying attention to the temperature they want. Even if you pay attention to all these, your base definitely starts to warm up after a point. Then the best solution is to pump the oxygen you will produce in a cold place to your base. A simple solution would also be to plant Wheezleworts, which grow in the ice biome and serve to cool the area slightly, in the warm areas of your base.

You will encounter all kinds of creatures on the asteroid.

It is possible to tame all of them and benefit from their meat and wool. But the most adorable thing you will encounter will be the very cute (!) thing called Hatch. It's very convenient to grow them because the things they can eat are tons of stuff that doesn't bother you.

Also, the purpose of Hatch breeding is to "convert" what they eat into coal, rather than their meat and eggs. Thus, it is possible to produce your own "animal coal" for the coal generator. But for this to be effective, of course, you need to create a 5-6 room Hatch farm. You also need clones with the "ranching" ability. Of course, you can make barbecue, which is a high morale meal, with the meat of animals that have died of old age, or you can "clean up" the excess, but I do not recommend it, the more Hatch, the more coal after all.

You should be very concerned about the happiness of your Hatchs, because an unhappy, unmet Hatch has a longer spawn time and less coal it gives. Having a very crowded Hatch population in a room is usually the biggest problem, so you need to make at least 5-6 separate rooms, check the Hatches often and make sure that they are not "cramped (overwhelmed by the crowd)".

You can also create different types of Hatch depending on the food you serve. Stone Hatch is the most ideal for coal production.

Apart from coal and food source, the shells left from the eggs of animals are also a very important source for lime production. We also use lime to produce steel in the future. In this sense, you can obtain a solid shell production especially from the fish farm.

Automation Systems

Automations are extremely complex, but after persevering and learning, they are very enjoyable to use and save you a lot of drudgery, and most importantly, they are systems that prevent you from wasting your resources. For example, let's take the example of the most used automation, the Smart Battery. When you connect a regular battery to a generator, the generator will run and charge the battery as the battery discharges.

But the smart battery saves power by cutting off more power from the generator until it drops below a certain level you set. Or, let's say you built a machine, just like Carbon Skimmer, to clean the carbon dioxide in your base, you can create an automation command such as "work if you detect carbon dioxide at this pressure, otherwise don't work".

Thus, the machine does not consume electricity in vain. There are many more automations like this. Timers, heat and liquid sensors, automatic collectors of materials, etc. It is necessary to prepare a separate guide for automation, which will take pages, so I cut it off here, but I definitely recommend you to learn it in order to use everything effectively and to enjoy the game extra, there are a lot of very instructive guides on the internet.

Besides, if you say "I don't want to look at the internet, I want to solve this problem myself". My advice is to open the game in "sandbox mode" and practice there. Otherwise, your duplicants will draw from you when you try to try it in your real game.

Our life savers, those who come to our rescue in difficult times...

Considering that geysers are the only inexhaustible resource on asteroids, their value is beyond doubt. As you explore the asteroid, you will find various geysers.

Of course, the most useful ones will be the geysers that produce gas and water. Volcanoes that eject wrought metal are also very valuable, but dealing with them requires a bit of expertise, as the temperature rises to 500 degrees. You can learn about when the geysers will become active, how many cycles they will remain active for, and you can plan accordingly by having your clones examine the geysers, who are experts in the field of research.

Since the active geyser will be extremely hot, you usually have to wait for it to stop to build the structures. You can get unlimited power from gas geysers, but when it's active, you're left bare. That's why I suggest you build a lot of gas tanks/reservoir to handle you until the geyser is active again. The water geyser unfortunately produces extremely hot water, it can be around 60-70 degrees and sometimes even hotter. Pumping it directly to your base means your base will overheat in a short time. In addition, using this water on the plants you grow also warms the plants.

The solution might be to cool the water pipes through the ice biome using normal pipes, and keep it warm by using an insulated pipe to bring it back to base. Or pumping extremely cold gas into the area where the geyser is is a solution. If you search on the internet, I'm sure you'll find some other ingenious solutions as well.

You are really surprised at the projects people have designed for this kind of games, Oxygen Not Included is a game for these "project people" anyway...

Your clones are human too, they can get sick running around all day, right? So what are the types of diseases? Diarrhea or food poisoning caused by eating a bad meal goes away on its own. Your main problem is the disease called "Slimelung". This in turn comes from stale water, stale air, and slimes found in green, swampy biomes. Well, you can't stay away from these slimes, because both fungi want slime as fertilizer, and if there is no algae left in the asteroid in the future, you will still need slime for the machine that turns slime into algae. Since there is no escape from Slime, let's look at the methods that can prevent the disease: First of all, you must make a sink or hand sanitizer (Hand Sanitizer) next to your toilets. Also, make an air cleaner (Air Deodorizer) in the places where there is yellow-colored dirty oxygen in your base. Make sure to enter the swamp biome in one place and put disinfectant at the exit. So your clones will not be carrying germs to your base.

In addition, the slimes you accumulate in the warehouse lose their mass over time and emit nasty oxygen. The solution to this is to store the slimes in one place and put the tanks in liquid or places with intense gas pressure, because the slime maintains its mass under pressure.

Despite all these precautions, every clone will definitely taste slimelung disease. So what to do about sick clones? First of all, you have to set up a hospital room and produce medicine. I recommend you to produce the Balm Lily plant for this. You must also have at least two clones eager to become doctors. If there is medicine and a doctor, the sick clone automatically goes to the hospital and gets treatment. In other words, if you have medicine and your doctor, you do not have a serious problem with the disease. But as long as the sick clone is not healed, it spreads bacteria to the base by sneezing and sneezing, then of course it is possible to face an epidemic.

Along with Slimelung, injuries occur in clones that remain unprotected for a long time in extreme heat or cold environments. You should especially identify them and direct them to the hospital bed, they do not go away on their own because they are pathetic.

Since all three are related to each other, I thought I would discuss them in a single topic. You give your clones various specializations according to their interests, such as "you do electricity, you become a cook".

Of course, they do not do a single job, and over time they may acquire other specialties. In addition, to be able to do some work requires expertise, such as animal husbandry, medicine. Every specialization means more morale requirements. You can give specialization that will require 20 points to a clone with 15 points of morale, of course, there is no obstacle in this regard in the game, but the downside is that; your clone who can't reach the required morale points says "I do this much work but it doesn't provide me with a suitable environment, he uses me, I'm very unhappy" and the stress factor is increasing.

Even though the stress is up to 60%, the clone either vomits and spews dirty water, eats it all the time, washes things up, or cries out and floods it. You can see the stress response of each clone from the clone properties. To prevent stress, we must first keep morale high. For this, you need to make several rooms.

For example, a room consisting of only dining tables is called a "dining room" (mess hall), and it gives +3 morale to the clone at every meal time. But when you put decorative items such as a painting, a light, and a water dispenser, it becomes a "dining hall" (great hall) and provides +6 morale.

If you make bedrooms, bathrooms, rooms where the clones can socialize, play arcades, morale will skyrocket.

At the same time, if you make a lot of paintings and sculptures in places where the clones spend their time, their morale will increase from the decor points. In order for artworks to be masterpieces, you must have them made by a clone with high creativity ability. So you too can have a clone Mona Lisa.

In order to escape from the asteroid, of course, you must first go into space.

But this is only the beginning of the work. Space is a whole different part of the game and I would say don't go to the surface without knowing what to do. Beforehand, you must ensure that your colony is trouble-free.

Once you've made sure your food and power generation is adequate, your base's temperature is at normal levels, and you're supplying your base with enough oxygen, start thinking about space, so don't rush. For space missions, you must have started the production of glass and plastic, especially steel. But before you start steel and glass production, I suggest you produce a lot of plastic. So you do transit tubes up to the surface and you'll have considerably shortened the time your clones walk from the base to the surface, otherwise long walks slow things down a lot.

You can deal with a lot of problems such as overheating, broken pipes, insufficient power, because at these stages. Afterwards, after you are sure that steel and glass production is running smoothly, you can turn your eyes to space.

So, before you start playing oxygen not included, keep this in mind:

At first you will find it very difficult, you will be very angry.

Be patient and check the connections of everything in the game very well. And don't forget to use the game's Google while doing this.

Because when you miss a tiny detail, after a few cycles, duplicants will start to be unable to breathe due to the pressure, it will stress them out and they will start pissing everywhere and crying for nothing :)

Enjoy the game..
