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 choose to add one of 3 new randomly generated duplicants, or, as of QLM2, items, food, or resources every 3 Cycles in the Printing Pod. Though each set of 3 is new, a new set of 3 will not be generated until the player selects one to print or rejects all available bioprints upon which the Printing Pod will begin generating another set.

Duplicant selection

Duplicantprintdialog — The Duplicant selection dialog as it appears during the game.

At the start of the game, three duplicants are given. The player may regenerate a duplicant, removing it and replacing it with a new, randomized one, and are not limited to just three options. 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 three possible 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, as of QLM2, to select one of the items, food, or 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

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

Attributes

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 20, 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.

A duplicant will start with 7-10 points randomly allocated into attributes, with that number being modified by any traits that they have. For instance, a duplicant with fast learner and flatulent will have 6-9 points to allocate, as fast learner removes 3 and flatulent adds 2.

The following attributes are available:

Traits

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.

Also note that changes to skill distribution via traits has no effect on the maximum attribute level learn-able, which is +20 not counting attribute or job modifiers.

Interests

Each duplicant will have between 1 and 3 interests. Interests reduce the morale requirements from learning associated Skills.

Properties

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

Morale has an impact on how much Stress is incurred or reduced and is affected by several factors. Generally, there are very few Morale Penalties.

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 3.300kcal 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 3300kcal, 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.

Stress Responses

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

Ownership

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

Duplicants occasionally express emotions or reactions to things around them. This indicates their status in ways that the player can keep track of.

Icon	Description	Icon	Description
	"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

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 Liam and Meep which can only spawn from the Printing Pod after the start.
