Humanoids, animals, and mechanoids sustain injuries from sources including melee weapons, weapons fire, explosions, ceiling collapses, and fire. Each source of damage comes with a specific Damage Type. Colonists, visitors, and prisoners can be operated upon and may suffer an injury from a surgical mistake. Each kind of injury has a value of pain, a description for its scar, and flavor text for being mended by medicine. A colonist in shock from extreme pain or incapacitated due to loss of movement becomes 'downed'. Doctors will automatically rescue downed colonists.

Feelin' the Pain
- Main Article: Pain
Most biological creatures including colonists, raiders, and animals feel pain caused by injuries. A pawn's pain level ranges from 0% to 100% and is displayed on their Health tab's Overview. Pain levels are None, Little, Moderate, Severe, and Extreme. Even a little pain causes unhappy thoughts. Once pain passes 10%, it'll start to have an effect on consciousness. If a pawn's pain level meets or exceeds their Pain Shock Threshold they'll go into shock, unable to move. Pawns with the Wimp trait will be incapacitated with only minor pain of 15%.
Most pain is temporary, but scars and certain diseases can cause long-term pain. A painstopper implant will get rid of all a colonist's pain and negate any pain-related mood penalties. Note that colonists with the Masochist trait get a mood bonus from pain instead of a penalty, so it's usually better to leave them alone.
Pain follows a somewhat complex formula:
- This is 1.0 for humans.
- This is also 1.0 for humans
Extra pain is determined by individual injuries:
Extra Pain = Injury Damage × Injury Pain Value
- 50 crush damage would do 50 damage × 1.25 crush pain = 62.5 extra pain
- 50 burn damage would do 50 damage × 1.875 burn pain = 93.75 extra pain
When a pawn's food meter reaches 0% they will begin to suffer from malnutrition, shown on the Health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.
- Malnutrition starts at 0%; upon reaching 100%, the pawn will die.
- Malnutrition (trivial): consciousness -5%, 150% hunger rate
- Malnutrition (minor): consciousness -10%, 160% hunger rate
- Malnutrition (moderate): consciousness -20%, 160% hunger rate
- Malnutrition (severe): consciousness -30%, 160% hunger rate
- Malnutrition (extreme): consciousness max 10%
- Malnutrition (100% severity): death
Blood loss occurs when a pawn has untreated bleeding wounds. Bleeding wounds are identified on the Health tab by a blood icon and a tooltip shows the bleeding rate. Total blood loss is listed under Whole Body and its tooltip shows the total blood loss. Overall bleeding rate is shown at the bottom.
Once all bleeding wounds are healed the pawn will start recovering from blood loss. It takes up to 4 days to fully recover as of Alpha 17, up from 50 real-time seconds in previous versions.
- Blood loss starts at 0%; upon reaching 100%, the pawn will die.
- Blood loss (minor): consciousness -10%
- Blood loss (moderate): consciousness -20%
- Blood loss (severe): consciousness -40%
- Blood loss (extreme): consciousness max 10%
- Blood loss (100% severity): death
Caused by extreme pain, it incapacitates the affected target. There are no other causes of shock besides pain currently.
Pawns go into shock if their amount of pain is greater than 80%, except for wimps which are downed at 15%.
Heat stroke occurs when a pawn has prolonged exposure to temperatures well above their maximum comfortable temperature.
- Heatstroke (initial): consciousness -5%
- Heatstroke (minor): consciousness -10%, moving -10%
- Heatstroke (serious): consciousness -20%, moving -30%, pain +15%
- Heatstroke (extreme): consciousness max 10%, pain +30%
- Heatstroke (100% severity): death
Hypothermia occurs when a pawn has prolonged exposure to temperatures well below their minimum comfortable temperature.
- Hypothermia (shivering): consciousness -5%, manipulation -8%
- Hypothermia (minor): consciousness -10%, manipulation -20%, moving -10%
- Hypothermia (serious): consciousness -20%, manipulation -50%, moving -30%, pain +15%
- Hypothermia (extreme): consciousness max 10%, pain +30%
- Hypothermia (100% severity): death
Scars are permanent markers of injuries. They permanently lower the maximum health of the scarred body part, making it easier to damage the affected body part in the future. They also cause a character a small amount of pain, even if the relevant body part is fully healed. Pain from scars results in a permanent mood penalty for non-masochistic characters. For a colonist with the Masochist trait, scar pain will provide a continual mood bonus instead of penalty.
Scars can be caused by poor quality treatment or simply not treating wounds, though injuries have an inherently low chance to scar, as seen above. Sometimes colonists are generated with minor scars and old gunshots already in place. Some body parts also scar instantly upon injury.
It is possible to remove the pain from scars by replacing the scarred body part. This is obviously only possible for limbs and eyes as there's no way to remove the torso, neck or head.
Scars can be treated by luciferium, however the cost of using it usually outweighs the benefit, unless used on numerous scars, or a permanent brain injury.
Another way to work around scar pain is to implement a Painstopper, preventing all ongoing pain. The downside to this however, is that should the pawn with an installed Painstopper take serious damage - they won't go down until they either lose a leg (or have it heavily injured), or die. Therefore you should be extra watchful of their health as to decide whether to withdraw them from a controllable scenario (i.e. combat), as to prevent them from losing their life.
Heart Attacks can randomly occur on any pawn at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in Humans), triggered by Birthday event.
The average interval between heart attacks is curved as follows (in days).
0-50% of LE: 99,999,999 - 99,999,999
50-60% of LE: 99,999,999 - 2,500
60-100% of LE: 2,500 - 300
Examples of intervals and chances:
55% of Life Expectancy (e.g. 44 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
80% of Life Expectancy (e.g. 64 in humans): 1,400 days (approx. 0.000714% per day)
A heart attack has 3 stages.
Painful: 0 - 59% severity
- Consciousness x50%
- Pain +40%
Debilitating: 60 - 99% severity
- Consciousness max 10%
- Pain +60%
Fatal: 100% severity
Heart attacks always start at 40% severity. Every 5,000(83.33 secs) the heart attack severity will randomly change by a value between -40% to +60%. This means that it is possible for a heart attack to treat itself on its own, but usually the heart attack progresses to fatal severity.
Like injuries, medicine can be used to treat a heart attack.
Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by 30%. Successfully reducing severity below 0 will completely treat the heart attack.
The maximum chance a particular treatment can succeed is 65%.
Strictly speaking, these aren't truly injuries but the result of old age taking its toll on a colonist's body. Chronic diseases are significantly more likely to occur past a pawn's life expectancy. All occurring ages are based on humans, and will obviously be different with animals dependent on life expectancy. Humans stop getting birthdays past the age of 99.
Alzheimer's (From Age 36)
- -5%/-10% (Minor)
- -15%/-20% (Major)
- Thoughts will be removed occasionally
- Occasional Confused Wandering, like with Dementia
Artery Blockage (From Age 21)
- Blood Pumping
- -5%/-10% (Minor)
- -15%/-35% (Major)
- -60% (Extreme)
- Death upon reaching 100%
- More Frequent Heart Attacks (on average every ... days)
- 600/500 (Minor)
- 300/200 (Major)
- 120/Death (Extreme)
Asthma (From Age 2)
- -5% (Minor)
- -15%/-25% (Major)
- Applied to both lungs giving double the harmful effects
This can not be treated completely, but can be prevented from progressing, or have its severity reduced through treatment.
Bad back (From Age 41)
- Movement: -30%
- Manipulation: -10%
Carcinoma (From Age 25)
- Pain (Note: 30% chance not to cause pain)

- 60%/70% (Extreme)
- Part Efficiency Loss
- 10%/25% (Minor)
- 50%/80% (Major)
- 90%/Destroyed (Extreme)
Note that Carcinomas always start at 0.3 severity, meaning 20% pain and 25% efficiency loss. The only way a Carcinoma is at its least severe is if it's been in remission for long enough.
This is when below 0.15 severity.
Cataracts (From Age 49)
- Sight: -35%
Dementia (From Age 69)
- Consciousness: -15%
- Talking: -40%
- Hearing: -40%

Frail (From Age 51)
- Movement: -30%
- Manipulation: -30%
Hearing Loss (From Age 49)
- Hearing: -35%
- Applied to both ears giving a total of -70% hearing
Some of these 'injuries' can be replaced by natural or bionic implants.
A pawn may become a trauma savant upon taking and surviving an injury to the Brain. Certain capabilities will rise and some will fall.
Trauma Savant currently removes all ability to socialise and opinions of others, capability of Talking and Hearing (both capped at 0%), but increases Manipulation by 50%, and restores full brain functioning (meaning consciousness and other functions will be normal) - this is great for doctors and general workers, but it'll make affected wardens or traders a write-off in that aspect.
There is a 12% chance of any pawn becoming a trauma savant upon receiving brain damage. It does not have to be a humanlike, and can sometimes be seen applied on animals.
