Colonists

Colonists are brave souls who decide to settle Mars and risk death and injury with no possibility of rescue. Colonists begin arriving once you create a colony with domes that can sustain human life and require care and attention. Notably, each colonist has their own personality and distinct set of likes and dislikes, which can evolve over time. Colonists require the resources Oxygen, Water and Food to survive.

Applicants are potential colonists and may be chosen based upon the traits and specializations listed below. The Sponsor determines the number of initial applicants available and various technologies and sponsor traits may also influence the number of applicants available. Non-age related colonist deaths reduce the pool of available applicants by 2.

Colonist Behavior[edit]

Each colonist prefers to work in a building that matches their specialization (below). If no such job is available, then they will fill spaces depending upon the priorities that you have set. They also have characteristics such as comfort and sanity that must be managed lest the colonist become Earthsick and demand to leave on the next shuttle home.

Colonists will only work within the dome that they live in, but they can walk from dome-to-dome or take a shuttle (provided via the Shuttle Hub) to transfer from one dome to another should you choose to manually set their new home or new work in a different dome.

Colonist work assignments follow these rules, in order:^[1]

The player can manually assign individual workers, ignoring all rules below. Ideally we hope that there will be no reason to do so, unless the player particularly likes to micromanage. Clarification: Manual assignment is not permanent, so after a long period(5 sols) the colonist may decide to switch jobs.
Buildings with the highest priority are fully staffed if possible
If there is not enough workforce higher priority buildings will be fully staffed while lower priority buildings will be partially staffed, but the game will try to keep them operational if possible (e.g. all buildings at high priority staffed at 100%, all buildings at the medium priority staffed at roughly 50%, all buildings at low priority staffed at 0%)
Specialists prefer to work according to their specialization, as long as this doesn't mess up the above rules.
Keep in mind that since everything depends on the individual simulation, you may have to wait for 1-2 sols until all workers find their desired workspots, so in any current moment there may be a situation where e.g. a Botanist is working in a Bar and a colonist without a specialization is working at a Farm. This is temporary and should be resolved automatically after a while.

Note that the colonists won't try to find a job at another dome. You'll need to manually optimize the domes settings to make sure the properly specialized colonists live in the properly specialized domes.

Stats[edit]

Each Colonist has four Stats: Health, Sanity, Comfort and Morale. These Stats have a value between 0 and 100 and are modified by various factors and events (Traits, quality of life, workplace, disasters, etc.).

Stat	Effects	Increased by	Lowered by
Health	Colonists can't work at low Health unless they have the Fit Trait Colonists die at 0 Health 70 or more +5 Morale 50 or less -10 Morale	Well rested +5 or +10 with Fit Trait Visiting buildings with the Exercise or Medical Checks service	Having no Food, Oxygen or Water Working heavy workloads Injury
Sanity	Colonists can gain Flaws at low Sanity Colonists have a 50% chance to commit suicide at 10 Sanity unless they have the Religious Trait 70 or more +5 Morale 50 or less -10 Morale	Well rested +5 or +15 with Smart Home Visiting buildings with the Medical Checks service Psychologist Commander Profile +5 Being in a Dome when the Good Vibrations Breakthrough is researched +5 Sanity each Sol	Working Night Shifts Working heavy workloads Working outside Domes Disasters Death of a Colonist from the same residence
Comfort	Couples are more fertile at higher Comfort Colonists quit their job at 0 Comfort and leave on next Rocket unless they have the Martianborn Trait 70 or more +5 Morale 50 or less -10 Morale	Resting in a residence or visiting a building that service the colonist's Interest +X Comfort is only applied if the building's Comfort is higher than the colonist's current comfort X is the building's Comfort Increase. This is 10 for most buildings. Biome Engineering gives +5 Comfort to each residence in the dome for each working farm Each Vista in a Dome working area give +10 Comfort to each residence in the dome Hanging Gardens +30 Comfort to each residence in the dome Working in a Workshop +1	Homeless -20 each Sol Not visiting buildings that service the colonist's Interests Not getting food from a building with the Food service
Morale	+1 point Worker Performance for each +1 Morale point above 50 Moral -1 point Worker Performance for each -1 Morale point below 50 Colonists can become Renegades if Morale stays below 65 for too long	Health, Sanity and Comfort are 70 or more +5 for each Having the Religious Perk +10 and +20 more for a Colonist with the Saint perk in the same Dome. Interacting with a Colonist with the Empath perk +?? Working in a Workshop +10 Dome with a Spire and Inspiring Architecture +20 Story Bits decisions	Health, Sanity and Comfort are under 50. Story Bits decisions

Age Groups[edit]

Colonists are divided into five age groups according to the stage of their life.

Age group	Age range	Age duration	Description
Child	0-5	5	Children are too young to work and use many of the buildings in the Colony. They can go to School and use certain special buildings such as the Playground and Nursery.
Youth	6-10	5	A young Colonist, able to work in all buildings.
Adult	11-30	20	An adult Colonist, able to work in all buildings.
Middle Aged	31-60 (31-80)	30 (50 with Stem Reconstruction tech)	A middle aged Colonist, approaching retirement, but still able to work in all buildings.
Senior	61+	0-17 (random duration)	A senior Colonist, too old to work.

Birth[edit]

For martianborn children to be born, there should be fertile Male/Female couples in the Dome. Colonists with the Other gender are not fertile.

Each fertile couple effectively has a ((comfort-30)/10)% chance per Sol to have a baby. More technically, all fertile couples contribute (comfort-30) points daily to the shared pool of birth progress points in the dome. When that number reaches 1000, a baby is born.

Without accounting for technologies, considering a 55 year fertile life and an ideal men/women ratio, you can expect these population trends based on comfort:

Average comfort	Sols per child	Children per couple per 55 sols	Trend
55 (minimally fertile with Medical Checks)	40	1.375	inevitable extinction (-1.1%/Sol)
66.4	27.5	2	stable population
70 (min without Medical Checks)	22.2	2.475	steady growth (+0.85%/Sol)
100 (max)	13.3	4.125	rapid overpopulation (+7.5%/Sol)

Specializations[edit]

Citizens perform better at workplaces that match their specialization. All colonists receive a penalty if working the wrong type of work. Colonists with no specialization can learn one at Martian Universities. Specializations also determine a colonist's main interests.

Specialization	Dress code	Ideal Workplace	Interests	Description
Child	white	none	Playing	One of the youngest residents of the colony.
No Specialization	teal	Non-specialized work (Diner, etc)	Social, Relaxation, Shopping	A brave citizen of Mars, ready to tame the final frontier.

Scientist	white	Research Lab, Hawking Institute	Social, Relaxation, Gaming	A trained scientist, eager to discover the mysteries of the Cosmos.
Officer	red	Security Station	Relaxation, Social, Exercise	A trained security officer, protecting our Utopia.

Traits[edit]

Traits are the defining characteristics of a colonist and can give various bonuses or penalties. Some Traits will also add an additional interest to colonists unless their specialization includes it already.

Perks[edit]

Perks are beneficial traits and should be sought amongst applicants. Children colonists can gain any random Perks when visiting the Playground or selected Perks when visiting the School buildings.

Colonists with specific Flaws can replace them with any random Perk by visiting the Sanatorium spire that has the Behavioral Melding upgrade.

Any non-Child colonist can gain 1 random perk, over time, when the Project Morpheus wonder is working. Any non-Child colonist can gain the Fit perk when visiting the Open Air Gym .

Flaws[edit]

Flaws are detrimental Traits and should be avoided amongst applicants.
Every applicant has a 50% chance to lose any 1 flaw when launched to Mars if Space Rehabilitation has been researched.
Colonists will lose the following flaws when visiting a Sanatorium spire: Alcoholic, Chronic Condition, Coward, Gambler, Glutton, Lazy, Melancholic.

Quirks[edit]

Quirks are Traits that don't fit into other groups or that are generated by events or Mysteries.

Quirk	Description	Source
Biorobot	Synthetically created humans that function similarly to us - they breathe, they eat and they sleep. However they do not age and cannot reproduce.	The Positronic Brain
Clone	Has half the lifespan of a naturally born human.	Cloning
Dreamer	Dreamers make sense of the shared dream but lose 23-ish Sanity during Mirages. ( Sanity loses are affected by Coward 200% loss and Composed 50% loss) Before completing Inner Light, these colonists become unconscious for 1.5-ish Sols while dreaming and are unable to work during that time. After completion, these colonists gain Dreamer's Inspiration, which gives +10 performance. Both during and after Inner Light, colonists can gain this trait by being born with it OR learning it from schools and other methods from which perks are gained.	Inner Light
Dreamer	The Dreamers have emerged from the Mirages with renewed hope. +15 performance from Dreamer's Inspiration. When the mystery is completed, colonists have the previous Dreamer trait replaced with this one. You cannot train anymore Colonists to have this Dreamer trait after the mystery has been completed. Also, colonists are capable of regaining the previous Dreamer trait and having both. This causes a bug where the colonist no longer get +15 performance and only gets +10 performance.	Completing Inner Light
Founder	One of the first Martian Colonists.	First Rocket Colonists
Guru	Randomly spreads other traits of this colonist to persons in the same Dome with less than 3 traits.	Applicants
Martianborn	Martianborn Colonists never become Earthsick. The Martianborn group of techs can improve this trait significantly. Can't get Earthsick. Can become Renegade instead.	Born on Mars
Refugee	Untrained for life on Mars, which results in decreased performance at all jobs. Cannot be Earthsick. High chance to become a Renegade. Worker Performance -50* for 5 Sols.*	The Last War Refugee Crisis
Tourist	Doesn't work. Grants $10 Million Funding on arrival. Leaves at first opportunity after 5 Sols. More Tourists appear when Tourists successfully return to Earth. +Gambling	Applicants
Vegan	Has decreased Comfort when living near a Ranch and won't work in such buildings. Has increased Comfort when away from Ranches. Farm in the Dome +2 Comfort every Sol. Ranch in the Dome -2 Comfort every Sol.	Applicants
