Players who are new to Oxygen Not Included would find themselves having a lot of early game issues due to how unforgiving the game can be when problems arise. Not swiftly addressing these issues will lead to catastrophic events, like having germs all over the base, having Duplicants with extreme stress response, and ultimately, losing a Duplicant as they pass away. For that, it’s important to know what to do first in Oxygen Not Included. Having a strong foundation that fulfills the Duplicants’ needs will guarantee players’ survival for a long time. Even if they’re not fulfilling the end-game goals, knowing how to survive is one step closer to those shiny achievements.

Choose Your First Duplicants

Don’t Underestimate The Negative Traits

When players start a new game in Oxygen Not Included, it’s highly recommended to have one digger and one researcher, with the third Duplicants (Dupes) being another digger or a builder. These roles can be customized using the arrow button next to Reroll on top of the Duplicant selection box. Picking these roles specifically allows players to immediately have a Dupe that’s good at digging and researching, meaning it’s easier to expand the base later.

Create Different Schedules

Congregating At The Great Hall

Your Duplicants have work, break, and sleep times. During the break, they will go to the bathroom, eat, and rest. Because of this, it’s crucial to spread resting times between Duplicants. If they all have the same break time, there will be times when no one is attending to the base, which can be detrimental if a utility becomes unavailable in the middle of break or sleep time. This also minimizes the number of Outhouses needed, since they won’t go to the bathroom at the same time.

Next, set a Duplicant Priority for your Duplicants. This will make a Dupe focus on their high-priority task. For example, a Dupe with high Science should prioritize research, whereas the digger should prioritize digging. There’s also a Building Priority feature to make a Duplicant focus on certain tasks, or even force them to leave everything and do the task you want with the Top Priority button (red button with exclamation marks). Make sure to only assign a high priority to tasks that are extremely important, since if everything is important, the Dupe will just treat them equally.

Find Water And Build An Outhouse

Just Go To The Bathroom!

After entering the game, the next steps are to find water sources and build an Outhouse. This is a high-priority step, since your Dupes will spread germs and polluted water if there’s no place to relieve themselves.

Place the Great Hall (dining room) above the Latrine (toilet), as Dupes always go to the restroom before eating.

Once a water pool is in sight, dig into it and place a Pitcher Pump (make sure the pipe touches the water) so that the Duplicants can get water. Next, build an Outhouse nearby along with a Wash Basin for the Dupes to go to the bathroom and wash their hands. Without a place to wash their hands, the Duplicants will also spread germs all over the base, so make sure not to miss this step. Additionally, it’s highly recommended to build a Latrine room for Morale boost. A room can be made simply by making sure the surrounding areas are closed off by walls, tiles, or doors.

Make Barracks With Cots

Sleep Like A Baby

Once a proper toilet is set, the next step is to ensure the Duplicants aren’t sleeping on the floor. For this, build a Cot for them. Like with the Outhouses, players can make Barracks by closing off the openings with walls or doors.

It’s highly recommended to make Barracks four-tiles high, so it’s easier to switch to Luxury Barracks later.

For a further Morale boost, start researching the Mess Table, Water Cooler, and Flower Pot to create a dining room called the Great Hall​​​​​​.

Research Quickly

Get Access To Advanced Items

As it’s already mentioned, one of the first things players should aim for is completing crucial research. Players can use the Printing Pod as an early light source to enable the Laboratory room. Close the walls, then simply build two Research Stations to enable the lab. Make sure to put the Manual Generator outside the room, as it’s not allowed inside the Laboratory.

Don’t Starve Together: 7 Easiest Crock Pot Recipes

There are plenty of amazing Crock Pot food in Don’t Starve Together, but these are the easiest ones to make, especially in the early game.

Additionally, the starting Battery is a small one, so leave one tile of space to replace it with a better Battery later. Finally, connect all the structures together with a Wire to get them running.

Small Farm To Keep You Running

Don’t Starve Together

Oxygen Not Included provides a small amount of food at the start of the game, but players quickly have to find alternative solutions once the other basic structures are made. As players research the Mess Table, they should have already unlocked the Planter Box. The easiest early-game food is planting Mealwood, but later on, it’s better to switch to other plants like Bristle Blossom or Dusk Cap. Don’t rely on Mealwood without figuring out how to renew Dirt, because although Dirt is abundant in the early game, players can run out if they only use it without finding renewable methods.

It’s best to pick a space under the base where carbon dioxide pools so that the plants can always have enough gas pressure as required for their growing requirements.

One of the ways to renew Dirt is by ranching Pip. On the Terra Asteroid, Pip is available as a random care package from the Printing Pod. Plant Thimble Reed or Arbor Tree to feed them. Players can make a Pip plant the plant’s seeds on a natural tile or build a Hydroponic Farm that takes Polluted Water. The Polluted Water can be sourced directly from a Lavatory or Shower, reducing the need to handle the germ-filled waste.

Generate Oxygen

Just Keep Breathing

At the start of the game, some Oxylite tiles emit Oxygen, allowing the Dupes to breathe. But the reserve will eventually deplete, meaning players must find new sources of Oxygen. The easiest way to generate Oxygen is by using an Oxygen Diffuser or Algae Terrarium, but Algae will quickly run out through this method, so it’s crucial to quickly explore other options.

Don’t Starve Together: Every Character Ranked By Difficulty

Don’t Starve Together features many playable characters to choose from. Here’s every character ranked from the hardest to play to the easiest.

In the Terra Asteroid, there will be a good amount of water, so the best Oxygen generator is the Electrolyzer. The machine will generate Oxygen and Hydrogen, so it’s important to have them generated in a closed room and only spread Oxygen around the base. The best setup for this method is the Hydrogen Self-Powering Oxygen Module/Machine (SPOM), where the Hydrogen from the Electrolyzer is directed to a Hydrogen Generator to generate power, meaning the entire setup can power itself.
