The bionic heart is an organ replacement that replaces the heart and improves blood pumping, giving a small boost to a wide range of stats and tasks.


Bionic hearts 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 component, 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.


Summary stuff goes here


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

Removing the part requires ? of work, ?x medicine of ?? quality or better, and a Medical skill of ?.

If the operation fails, the part has a chance[What Chance?] to be destroyed.


It has 125% efficiency, improving blood pumping, which in turn slightly improves moving by about 5%. This gain is a multiplier rather than a flat improvement - other buffs to movement speed such as bionic legs or being affected by certain drugs will also be multiplied for an even larger increase. The bionic heart also improves the rest rate multiplier by about 8%.

By installing a bionic heart, the pawn's natural heart is harvested without a penalty, as the bionic heart is superior. This organic heart can then be sold or stored for later use.

Like bionic stomachs, bionic hearts are of less obvious importance than bionic legs, arms or eyes due to having lower bonuses. However, the improved rest effectiveness, though small, will improve the productivity of a colonist, allowing them to do more work each day. Over time, this can really add up. Likewise, the movement speed boost can make a difference when fleeing animals or mechanoids or in caravans.

The bionic heart also stops and prevents heart attacks, which makes it very useful for drug-users or old people, especially if they have an artery blockage.

Unlike the prosthetic heart or a natural, biological heart, there is not a 25% chance of instant death in the event of failed installation. This makes it significantly safer to install. It also only requires a medical skill of 5 compared to the organic heart's 8. The prosthetic is lower still, requiring only 4.
