This article may contain outdated information that is inaccurate for the current version CU-273742. It was last updated for AU-219784.

Duplicants are the tiny, frustrating, but also endearing clones that the player manages in Oxygen Not Included. Each is generated or "printed" to be unique and has specific needs and vitals that must be fulfilled so they can survive. A new game begins with a selection dialog where the player has to select three randomly generated duplicants (or dupes). As the game progresses, the player may chose to add one of 3 new randomly generated duplicants every 3 Cycles. Though each set of 3 is new, a new set of 3 will not be generated until the player selects one to print, oozes all 3, or reloads their save file. You can effectively re-roll your choices by saving as the Printing Pod comes online. Then if you are not presented with a satisfactory selection load aforementioned save. You may repeat this an unlimited amount of times.

Duplicant selection[edit | edit source]

The Duplicant selection dialog as it appears during the game.

At the start of the game the attributes of the three choices may be shuffled. In that first selection you have to make sure that all duplicants have acceptable combinations of attributes and positive and negative traits. When you have reached an acceptable selection you may rename any duplicant as desired and then start the game.

In the selection dialog that appears every 3 cycles you can not shuffle the attributes of these three possible duplicants. You can either pick one or reject the entire selection. If your Colony can't handle another duplicant right now you can also ignore the selection dialog entirely. Until you either select a new duplicant or reject the selection the 3 cycle timer will be paused.

Duplicants will spawn at the Printing Pod and then immediately pick up a job if there is one available.

Duplicant properties[edit | edit source]

Each duplicant has a number of properties and conditions such as strength or health.

Attributes[edit | edit source]

Each duplicant has 11 different attributes that can be leveled up by mastering jobs. They define how effectively duplicants will perform those errands. From the start each duplicant usually has some attributes with a starting bonus sometimes influenced by their traits. Sometimes a negative trait may cause a duplicant to be unable to perform certain jobs altogether.

Most attributes can be trained, and the remaining will probably become trainable in future updates. The maximum level a skill can be trained to is 25, but traits that modify skills apply after that.

While a duplicant has a job, they will get a bonus that will be removed if they are unassigned from the job. After they master that job, the bonus will be permanent, and their expectations will increase.

The following attributes are available:

Name Description Bonus per level Trained by mastering

Traits[edit | edit source]

Inborn traits (traits duplicants start with) give bonuses or maluses to duplicants attributes. Negative traits may also make it impossible for a duplicant to perform certain jobs. Traits gained through certain jobs mainly allow for the duplicant to use certain stations and perform certain errands.

Interests[edit | edit source]

Each duplicant may have at most 3 interests. They enjoy performing related jobs and will master them 50% faster.

Properties[edit | edit source]

Properties are aspects of Duplicants that aren't leveled and can't be intrinsically changed (as opposed to Skills). However, many Attributes have positive and negative Traits associated with them.

Attribute Base Value Positive Trait Negative Trait Positive trait Second level
Oxygen Consumption 100 g/s Diver's Lungs (-25 g/s) Mouthbreather (+100 g/s) Deeper Diver's Lungs (-50 g/s)

Toilet Speed 100% None Irritable Bowel (-50%) None

Expectations[edit | edit source]

Duplicants have expectations for Decor and Food Quality. A duplicant's expectations will increase as they level up and become better at their primary job (highest skill level).

When in areas where the Decor is lower than their internal decor meter, their internal decor meter falls at -4.17 per second; and when it's higher, their decor meter will rise at 12.5 per second. If the meter falls below 0, it causes their Stress to rise at 10% per cycle ("Drab decor!"); if the meter rises above their decor expectation, it causes their Stress to decrease at -20% per cycle; otherwise there is no impact to stress. Decor expectation is initially -35, but is affected by some traits (such as "Uncultured" and "Interior Decorator"), and increases by 5 for each Duplicant Level (determined by the highest skill), up to a maximum of 75 increase from levels. The highest possible decor expectation is currently 45, at level 15 with the "Interior Decorator" trait.

Food has different quality ratings, ranging from -1 to 5. Duplicant food quality expectations start out at -1, and food quality expectation can increased my mastering jobs. When eating food, the stress change increases by 150%/cycle for every point of difference lower than the duplicant's expectation and reduces by 300%/cycle for every point of difference higher than the duplicant's expectation. For example, a duplicant with an expectation of +2 eating a food with quality of -1 will receive a 450%/cycle penalty, as opposed to a duplicant with an expectation of -1 eating a food with quality of 1 will receive a -600%/cycle benefit. Eating takes about 30 seconds, so this results in +22.5% or -30% stress for the two examples.

Stress Responses[edit | edit source]

Each Duplicant has a different stress response. These responses trigger at 60% and 100% stress (stress is reduced after the 100% response). All responses stop the current job in order to perform the response. These responses cannot be stopped by Red Alert or commanding the Duplicant to move.

Name Description Response
Vomiter "This Duplicant is liable to puke everywhere when stressed" Vomits on the floor, producing 200 g/s Polluted Water
Destructive "This Duplicant will take out their frustrations on defenseless machines when stressed" Damages nearby equipment and tiles, cannot repair buildings above 60% stress
Binge Eater "This Duplicant will dangerously overeat when stressed" Eats 2000 kcals of food 3 times before returning to 60% stress
Ugly Crier "If this Duplicant gets too stressed it won't be pretty" Sits on the floor and cries, producing 40 g/s Water, reducing Decor by 30

Each Duplicant can only be assigned to one, and they can be reassigned by the player at any time. They will automatically select them for themselves if left unassigned, or the duplicant becomes sick.

Emotions[edit | edit source]

Duplicants occasionally express emotions or reactions to things around them. This indicates their status in ways that you may want to keep track of.
