A bionic stomach is an organ replacement that has 125% efficiency, and increases metabolism by 12.5% (metabolism is the average of stomach and liver efficiency).

Acquisition

Bionic stomachs can be crafted at a Fabrication bench once the Bionic replacements research project has been completed. They require Plasteel 10 Plasteel, Advanced component 3 Advanced components, 26,000 ticks (7.22 mins) of work, and a Crafting skill of 8.

They can also be bought from exotic traders, Empire traders, and at Outlander faction bases. They are also sometimes offered as a quest reward.

Summary

Body part

A bionic stomach replaces the user's organic stomach. The bionic stomach has a part efficiency of 125%. This not only fully replaces the functionality of a normal stomach - when coupled with the stomach body part having a Metabolism importance of 50%, it results in an increase in metabolism of +12.5% over natural. Metabolism, in turn, improves the rest rate multiplier by +3.75%, meaning the colonist will require slightly less sleep.

Eating capacity, eating speed, and food poisoning chances are unaffected.

Other effects

Additionally, all artificial stomachs are immune to gut worms, and installing one will instantly cure the disease. Unlike the Royalty DLC stomach replacements, EMPing a pawn with a bionic stomach will not force them to vomit.

Installation

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.

Analysis

Of the bionic-level parts in the game, the bionic stomach offers one of the weakest improvements to a pawn. It gives a 3.75% increase to Rest Rate Multiplier, or, for an otherwise normal, healthy pawn sleeping in a Normal quality bed, a savings of just over 12 in-game minutes/day (a 1.2% increase in waking time/day). Additionally, gut worms are rarely a significant threat to a colony that can make or buy bionic parts. This makes seeking out bionic stomachs low priority but if you should happen to obtain one early, it is still worth installing. This also makes it a moderately attractive option for body modders and transhumanists.

The bionic heart is superior to the stomach, as it improves RRM by 8% and protects against heart attacks, but it's slightly more expensive. Both bionic hearts and stomachs can be used together, so in the endgame, there's no reason not to install both. Both bionic parts stack with other ways to improve sleep, like royal beds and sleep acceleratorsContent added by the Ideology DLC. See Rest for further details.

Stomach comparisons

The Royalty DLC introduced a number of Stomach replacements with their own advantages and disadvantages. All three of these variants include the benefits offered by the bionic stomach in addition to their unique benefits however they are also susceptible to EMP, causing the pawn to vomit uncontrollably for a short length of time.

Sterilizing stomach

In addition to the normal benefits of a bionic stomach, the sterilizing stomach eliminates the risk of food poisoning at the cost of vulnerability to EMP.

Reprocessor stomach

In addition to the normal benefits of a bionic stomach, the reprocessor stomach reduces the amount of food a pawn requires by 25% at the cost of vulnerability to EMP.

Nuclear stomach

The nuclear stomach combines the benefits of all other stomachs and reduces the amount of food a pawn requires by a whopping 75%, at the cost of vulnerability to EMP and inflicting torso cancer on average once 120 in-game days.
