Bionic arm

Bionic arm

An advanced artificial arm. Silenced mini-servos give great strength, while the biogel nerve-link gives exquisite control. A lattice-dust healing system allows it to recover from damage. It is better than a biological arm in almost every way.

A bionic arm is a very useful replacement for a natural arm. They are universal and can be installed on either left or right shoulders (despite its name). It has 125% efficiency, increasing a colonist's manipulation by 12.5% for each bionic arm installed. A bionic arm's strength gives its bearer a melee attack of 12 damage when an attack uses that arm, compared to 8 damage from a natural arm. An installed bionic arm will replace a colonist's arm up to and including the shoulder.


They can be crafted at a fabrication bench for 15 Plasteel plasteel and 4 Advanced component advanced components and are sometimes offered for sale by exotic traders and at Outlander bases. They require a crafting skill of 8.


Since bionic arms increase a colonist manipulation stat, it is advised to add them to colonist with a high skill level on Crafting or Medicine since those skills depend greatly on the manipulation stat. For example, a doctor will have a better chance at a high quality treatment if he or she has increased manipulation stats, and craftsmen will make objects faster.

As with all bionics, it will give a mood bonus to anyone with the Body modder trait and a heavy penalty to anyone with the Body purist trait.

Version history

In Beta 19 it received a nerf to efficiency (from 140%) but is now craftable.
