Health

Characters, like colonists, raiders, etc, can become injured (via the environment or fighting). Each injury affects a different part of the colonists' well being, and can be found under a character's Health tab.

↑ Refers to whether or not the pawn will die if a system's capacity becomes 'None'
↑ Centipedes body rings are used for movement instead, since they don't have legs.
↑ Again, Centipedes body rings are used for work instead, since they don't have arms.
↑ Centipedes have no form of external communication. Scythers do have a neck though, and make some interesting sounds when incapacitated (they sound pretty cute).

Treatment

For most injuries, you can treat colonists with or without medkits (with typically better results if you do use one), and also have them lay in hospital beds to further improve the chance of them being treated properly.

Improper Treatment

Treating an an injury poorly may result in scarring, reduced healing rate or infections

Operations

Under the Health tab, you can assign an operation to a colonist.

Transplants

For missing internal organs, either a donor organ can be used or an artificial one.

Limb Replacement

From peg legs to bionic arms, you could either replace a colonists' missing limbs, augment them, or cruelly punish your enemies with peg legs out of spite. Bionic parts have a bonus to specific actions or movement. For example, a bionic leg will increase your colonist's moving speed by 20%. Having a second bionic leg will increase the speed further by 20%, so having both right and left bionic legs will increase the speed by 40%.
