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 an artificial body part that acts as a replacement for a pawn's natural arm, increasing Manipulation by 12.5% per arm while also offering a slightly more powerful punch attack and acting as a body part weapon.


Bionic arms can be crafted at a Fabrication bench once the Bionic replacements research project has been completed. They require Plasteel 15 Plasteel, Advanced component 4 Advanced components, 26,000 ticks (7.22 mins) of work, and a Crafting skill of 8.

They can also be found in ancient shrines, offered as a quest reward, or bought from exotic traders, Empire traders, and at Outlander faction bases.


Body part[edit]

Bionic arms replace the user's organic arm up to, and including, the shoulder. They are universal and can be installed on either the left or right. The bionic arm has a part efficiency of 125%. This not only fully replaces the functionality of a normal arm - when coupled with the arm body part having a Manipulation importance of 50%, it results in an increase in manipulation of 12.5% over natural for each bionic arm installed. Manipulation, in turn, affects a great many stats. For a full list of affected stats, see Manipulation.


A bionic arm replaces the natural "Fist" attack of the replaced arm with an almost 50% more powerful, but otherwise equivalent, punch.

  • Installation[edit]

    Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal quality or better, and a Medical skill of 5.

    Removing the part requires 2,000 ticks (33.33 secs) of work, 1x medicine of herbal quality or better, and has no Medical skill requirements.

    If the operation fails, the part will be destroyed.


    First, any reasonably important pawn with a destroyed or prosthetic arm should get a bionic replacement. Then, the increase to manipulation is best used for the Doctoring, Crafting, or Construction; doctors tend faster and with higher quality, while crafters and constructors make objects faster (quality is unaffected). Manipulation is one of the few ways to increase general labor speed, so it is great for skill-less crafting tasks like stonecutting and smelting.

    Manipulation will also increase the Artistic, Mining, Plants, and Research (up to 110% Manipulation) skills, but these skills are generally less important to do fast in a mid- to late- game colony that can make bionic arms. The drill armContent added by the Royalty DLC and field handContent added by the Royalty DLC provide a much greater boost to Mining or Plants, though lower Moving in the process. For combat, bionic arms will increase Melee Hit Chance, but they only increase Shooting Accuracy if Manipulation is below 100%. While manipulation often goes below 100% due to the effects of pain and injury, bionic eyes are superior if combat, ranged or melee, is your main priority.

    Unlike organic parts, bionic arms don't contain subparts - all damage is taken by the main, 30 HP arm, instead of spread throughout the bones, fingers, and shoulder. While a bionic arm won't lose stray fingers to a gun shot, this makes it easier for it to be completely destroyed. Note that the bionic arm is fully attached to the shoulder; a flak vest completely protects a bionic arm, but does not cover an organic arm at all. In addition, the artificial part never feels pain and never bleeds.

    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. Similar effects are also applied to pawns following an Content added by the Ideology DLC ideoligion with a Body Modification precept.
