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 get more of them every 3 Cycles from the Printing Pod.
Duplicant selection[edit | edit source]
At the start of the game, three duplicants are given. The player may regenerate any duplicant, any number of times, removing it and replacing it with a new, randomized one. Player can also lock one interest per duplicant, guaranteeing that a new duplicant will have this interest (and possibly others). In this first selection, the player needs to make sure that all duplicants have acceptable combinations of attributes, and positive and negative traits. When the player has reached an acceptable selection the duplicant may be renamed, before the game starts.
In the selection dialog that appears every 3 cycles, the player can not shuffle the duplicants. The player can either pick one or reject the entire selection. If the Colony can't handle another duplicant right now, it is possible to ignore the selection dialog entirely or to select one of the care package items (food or other resources) instead. Unless the player selects a new bioprint, or rejects the set, the Printing Pod 3-cycle timer will remain stagnant.
Duplicants will spawn at the Printing Pod and then immediately pick up a job if there is one available, while items, food, and resources will drop in front of the printing pod.
Duplicant properties[edit | edit source]
Each duplicant has a number of properties and conditions such as strength or health. Duplicants weigh 30 kg.
Attributes[edit | edit source]
Each duplicant has 11 different attributes that can be leveled up by running related errands. 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 20, but traits that modify skills apply after that.
A duplicant will start with all attributes at 0, with that number being modified by any traits and interests that they have. For instance, a duplicant with interests in Supplying and Tidying and Buff trait, will have 9 strength and 0 every other attribute.
The following attributes are available:
|Name||Description||Bonus per level|
|Construction||Duplicant's building speed||+25% construction speed|
|Excavation||Duplicant's mining speed||+25% digging speed
+5% attack damage

|Agriculture||How quickly and efficiently a Duplicant raises plants||+5% farming speed
+~2.6% tending speed +~3.3% seed chance
|Husbandry||How quickly and efficiently a Duplicant raises critters.||+10% groom effect duration|
- Duplicant's initial carrying capacity is 200 kg
Traits[edit | edit source]
Inborn traits (traits duplicants start with) give bonuses or penalties 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.

Note that narcoleptic sleep can be interrupted by giving the Duplicant a movement command.
Also note that changes to skill distribution via traits has no effect on the maximum attribute level learnable, which is +20 not counting attribute or job modifiers.
Interests[edit | edit source]
Each duplicant will have between 1 and 3 interests. Interests reduce the morale requirements from learning associated Skills. Interests give +1, +3 or +7 to related attribute and the bonus depends on the number of interests - 3 interests give +1 to 3 attributes, 2 interests give +3 to 2 attributes and 1 interest gives +7 to one attribute. Note that certain interests, such as supplying and tidying, have the same corresponding attribute, so such dupe will get +6 to strength.
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)|

|Bladder Rate||100% per Cycle||None||Small Bladder (+100% per Cycle)||None|
|Toilet Speed||100%||None||Irritable Bowel (-50%)||None|
Morale[edit | edit source]
Required Morale depends on a Duplicant's highest job level or current training. 1 Morale is required if unemployed, 30 is the highest level. High Morale decreases Stress by up to 25% each cycle, low Morale increases Stress by up to +25%.
Duplicants have a perception of Decor and Food. The higher the average Decor during the last cycle and the higher the Food Quality, the higher the Morale Boost will be. Morale penalties will be incurred if below the individual's perception.
Without a modifier, the Morale from Food ranges from -1 to +16 or is modified 0 to +16 with the Simple Tastes trait and -1 to +12 with Foodie. Duplicants will start eating in their downtime when below 3.300 kcal and has the highest priority.
Normal Decor Perception is at 0, exceeding it can yield up to +12 Morale when reaching 120 difference and failing to will decrease Morale by -1. The Morale Boost is not linear.
Using rooms, having downtime and interacting with certain buildings will confer a Morale Boost. Duplicants will use certain furniture only if they do not yet have the Morale Boost and they do so in the order of the most possible Morale gained.
The highest Morale achievable is 49. The lowest is -1.
|[...] Meal||-1 to +16||Eat||Depends on the Food Quality and Perception, needs less than 3300 kcal, highest priority|
|[...] Decor||-1 to +12||Automatically recorded||Depends on average Decor of the last cycle and Decor Perception, 120 points above Perception gives the most points. Not linear.|
|[...] Shift Break||0 to +4||Have downtime on schedule||Bonus starts at 0 at 1 hour downtime and increases passive moral bonus by 1 for every hour added on downtime each cycle.|
|Comfortable Barracks||+1||Sleep in Barracks||Does not stack with Comfortable Bedroom|
|Comfortable Bedroom||+2||Sleep in a Bedroom||Does not stack with Comfortable Barracks|

|Duplicant||+1||Be a duplicant||How not to be is a mystery|
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.
|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|
Needs[edit | edit source]
Ownership[edit | edit source]
Individual Duplicants can have ownership of certain structures: Cots, Comfy Bed, Mess Tables, Massage Tables, Med Beds, and Pharma Chambers. 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 the player can keep track of.
|"I am happy"||"I am angry"|
|"I am enraged"||"I am unhappy"|
|"I am sleepy"||"I am sick"|
|"I am hungry"||"I can not breathe"|
|"I am cold"||"I am hot"|
|"I need the toilet"||"I like/hate better decor"|
|"Something smells bad!"||"I am binge eating"|
|"I am crying"||"I feel destructive"|
|"It's too loud!"||"I am stressed"|
|"I am vomiting"||"This is disgusting!"|
Established Duplicants[edit | edit source]
Duplicants have an assigned name, appearance, stress response and description (attributes, traits, and interests are still randomly generated). Changing the name of a Duplicant will alter the description as appropriate but will not change the appearance of the Dupe.
Almost every possible duplicant can appear when creating a new game, except for Ari, Mae, Ada, Meep, Liam and Banhi, whom can only be spawned from the Printing Pod after the start.
