How to start? | Oxygen Not Included Oxygen Not Included Guide

After choosing the game mode, we need to choose three duplicants with whom we will begin the game.

Choose colonists wisely, based on traits that they have, for example, Excavation

Three initial duplicates can be randomly generated indefinite amount of times. While choosing your characters, pay attention to following aspects:

1. Interests affect the morale of a duplicate while performing certain actions. In our case, Travaldo will receive an additional morale point when carrying items.
2. The amount of points added to the ability. When you point the mouse to this statistic, you'll learn what the benefits of the given ability are. Most of the time, you receive less fatigue when performing an activity, the time needed to complete the ability is lower, or bonuses in form of more carried weight, movement speed, or resistance to diseases.
3. The positive traits are marked in green, below you can find the benefits stemming from the. Most of the time, certain statistics will be increased, or you receive additional benefits. To view the benefit, point the mouse to one of the lines. For example, Decreased Food Morale lowers the morale penalty coming from bad food. As a result, the duplicant can eat bad food, without losing morale because of it.
4. The negative trait is marked in red, and you can view the penalty below. Point the mouse to one of the lines to display details. It is recommended to avoid traits that negatively affect the morale, as those decrease the speed of learning new abilities, or the time needed to complete the ability.

This line will tell you how the chosen duplicant reacts to stress. When stress reaches 90%, the character will act according to his trait. Vomiter will start to vomit, producing contaminated water, Ugly Crier will start to cry, lowering the morale of his allies, Binge Eater will eat until his stress level stabilizes, while Destructive will start to destroy the base.

Once the stress levels of a character reach 100%, your people may react in one of the following ways: they will vomit (Vomiter), cry (Ugly Crier), gorge on food (Binge Eater), or begin smashing your base to pieces (Destructive). It is much better to choose the characters that have the first feature, the vomit is simply contaminated water, which can then be used if you build the base properly. Cry, on the other hand, will affect others, increasing their stress levels. A glutton may become a deadly threat if you have limited food supplies, as he will eat through your reserves, leaving nothing for the others.

To summarize: At the beginning of the game, choose someone with Excavation, or upgraded Digging. The second hero can be a Builder or a Constructor. Choose the third character according to your own needs, for example, I chose someone with Farming. When it comes to stress reactions, avoid Ugly Crier and Destructive.

• The Beginning
• Further Development

The Beginning

Lots of algae and water. But the metals are missing, they are located only in the upper part.

1. Get acquainted with your surroundings. Maps are generated randomly, the same concerns the amount of resources and water. Sometimes you will find many caves with creatures or masses of buried objects around your starting location. At other times you will find abundant algae stocks or plenty of copper ore. It is worthwhile to find out at the very beginning, towards which side to dig and improve the base in order to get the necessary resources. In the picture above you can see three large water tanks with some Fertilizer around them. There are also 4 caves surrounded by algae and oxylite, which produces oxygen. Thanks to that, I will not have to rush oxygen production. In the caves, you will find plants, which you will soon grow; you just have to research your first technologies. Make sure you collect as much seeds as you can at this point. The only thing missing at the moment, is the supply of metal. The metals are quite high up, above the fourth cave. There is a vacuum right above the copper ore deposit. It will draw in air and dilute the level of gases in the base. I will avoid this area for now. The area is also lacking in buried objects, where I could find more seeds. Given this shortage, my fields will not be too bountiful at the beginning of the game.

An outhouse is crucial!

2. Expand your base and build an outhouse and some storage. The first step is to create a place for the outhouse. You have a supply of food and air. There is always a large supply of Oxylite around your printing pod. It will last for 2-4 days. However, if you do not have an outhouse, you will soon learn first-hand about the danger of your cave being drowned in contaminated water. Now build a few storage compactors, so that resources are not scattered all over the place. This is bad for the well-being of your duplicates. It will also be easier for them to build, without having to run around searching for resources in every corner. Set up each piece of storage for one particular type of resource, especially for the different types of raw metal and one only for algae from the organic category. You do not want to keep the contaminated dirt from your outhouses in the same place, right? Such dirt emits contaminated oxygen, even if it is inside a storage compactor.

Te first power plant can provide electricity for various devices for even a few circles with a single charge.

3. Electricity and first oxygen generators. Your next digging target should be copper depots. Copper will enable you to build energy generators and batteries. You should invest in many batteries and one, maybe two generators. This will optimize the effort and lengthen the time between need for charging. While the batteries are charged, duplicants can focus on other works. The room for the power plant, especially the first one, should have two fields of height. This will save you the space and enable you to construct all basic buildings that deliver energy. Once you create your first power plant, place wires to the research station. You should place then behind tiles and ladders, this reduces negative penalty to environment. Once the research table is connected, add a few first oxygen dyfusers. The best places for them are lower floors of the base, preferably close to the ladders - this will enable the oxygen to fly up and fill the whole space. Oxygen dyfusers must be connected with wires to the batteries.

If you place a storage compactor near the Algae Deoxidizer, and it will store only <br>Algae, it will speed up transport and shorten delivery times.

Now build the algae deoxidizer somewhere in the middle of your base, or in some other places where your colonists spend a lot of time (research facility, industrial block, dining hall). Connect the machine into the power grid in order for it to start producing oxygen. Such placement will allow the duplicants to breathe freely in key locations. It will require large amounts of algae, however, throughout the first several days you should have no shortages. The machine will produce oxygen until the concentration reaches a specific value in the room, usually 1800g per tile. Try not to expand rooms without a specific purpose. Do not delve into the algae terrarium for the time being. First of all, you will only need them in large quantities and only when carbon dioxide starts to be a significant problem. Secondly, they consume large amounts of water - a resource, that you will use in various other sections of your economy.

Your duplicants handle stress better, if they have somewhere to sleep.

4. The bedroom. When the most important matters are done with, you will have time to meet several needs of your duplicates. If you have already built an outhouse, this matter can also be considered as handled. It is worth building a second one, in order to avoid problems with queues when it comes to using or cleaning the place. Build a place where all of your colonists will sleep. You can of course build a separate room for each of them, but for now there will be a problem when it comes to providing oxygen to those locations. Place tiles around the room, use the sweep command to pick up the remnants of any resources. You can also build a lamp to improve sleep comfort. Thanks to the basic bedroom, you will avoid the first stress problems. Remember to place snoring duplicants in other, separate rooms. Snorers will interrupt other peoples' sleep, which will increase the stress levels and decrease their performance cause of fatigue.

Further Development

To gain novice research you simply need dirt, which you have an abundance of.

5. Research. Further development will be impossible without investing in science. Select a research station from the Stations tab. Place it near a battery, and connect it into the power grid. Before you start your research, make sure that the duplicate who has the best learning ability is the only one conducting the research. The Priorities tab will yet again be of help here. Now select the station. You will have a choice of doing novice research. To create one point of such research, you will need 100kg of dirt. Build a storage compactor nearby and let the duplicates store dirt in it. This way you will shorten the transport time. Then select the appropriate research by clicking the button in the machine's overview window or by selecting the tab in the upper right screen. You'll see a rather large research tree, where most of the techs will be of no use to you for the first two or three weeks. From the technologies in the first column, always start with " Basic Farming" so that you can create your own farming fields, which are the initial source of food. Then select "Interior Decor", so you can put up paintings, sculptures and tables for eating. Assign further research in ways suitable to the direction of your colony's development. Water tanks are too far away? Select the research that unlocks pumps. Too many different gases in your base? Choose ventilation and air filter research.

In this base, the water is very close to the starting location, which will make life easier for the duplicants. Building the compost will allow you to start producing fertilizer.

6. Gain water access. Now is a good time to create a passage to the nearest water tank. It will be helpful in creating meals and developing better research. Besides, is a very useful resource, fertilizer, is often in their vicinity. It will be essential to your agriculture, especially if you want to achieve better results and increased food production. Wybuduj You should also build the compost, from the Food menu. This allows you to process contaminated dirt into fertilizer.

Every three circles, the portal will glow. If you click it and press the blueprint, a window will appear. It will enable you to select bonus resources of duplicants.

Usually, you can choose from three duplicants and one set of resources, but sometimes you can only select between duplicants or resources. You should make the choice depending on the current state of your supplies and development level of your base. If you lack food and food supplies are available, you should select them. If you can choose from common resources, select a duplicant that will be good for your needs. In the first blueprint it is preferable to select a miner with high digging skill. Another miner will speed up the process of increasing the size of the base and help it expand. Each blueprint features various options to choose from.

A large farm is the groundwork for your survival.

7. Farms. It is time to discuss food production. After developing the first technology, you will be able to build the planter box from the Food tab. They occupy a lot of space, so build a new room exclusively for the plants. It is worth building them in the opposite part of the base, so that they are away from machines, batteries and all other devices that are emitting heat (the algae deoxidizer also generates heat). Most basic plant types dislike temperatures above 30 degrees Celsius. What's more, they have no positive influence on the Decor of your base. At the same time, remember that some plants also need the right concentration of air in order to grow. Too high temperatures will dry out some plants, resulting in no harvest.

Bristle Blossom grows slower, but it's healthier, has more calories, and can be harvested more often than Mealwood during its growth cycle.

While digging tunnels, you should obtain some seeds, and if their supply is still lacking, look around the caves which already have growing plants. Right now, only two plants interest you: Mealwood and Blossom. You can only sow these two plants and after a few days they will yield their crops. The latter needs fertilizer in order to be planted and also at each re-sowing. When they ripen, you will see white grains that move like worms on Mealwood. Meanwhile, Blossom will be ready to bed harvested when you see a big pink/purple fruit. It is a sign that you can issue the harvest command. Materials land on the ground, and when your duplicates are hungry or have too much time, they will collect them and transfer them to the appropriate ration box.

You can also build a machine for creating meals - the Microbe Musher (you will find both items under the Food tab). The advantage of this machine, is that it creates dishes which have more calories, even if you have no crops. The first meal you can get from the combination of dirt and water, but it can cause illness. The second, you make from Mealwood seeds and water, and it is twice as rich in calories as the first dish.

You can now explore into further regions or improve your base. Think about building more electricity production or more research stations. Construct a better research station - the super computer - close to a water tank. Focus on improving your base decor, which will reduce the stress of your duplicates. Remember, that the algae will run out and you will have to look around for an alternative source of this resource. Could it be better to think about other sources of oxygen production, such as water? This requires further research. Beyond your starting location, there begins a slightly darker section of space that has more hazards. On the other hand, there are also numerous other interesting places there. Build, explore, survive and remember that Oxygen is Not Included!
