Large mech gestator

Large mech gestator

A tank of mechanite-rich fluid with support tubes for feeding in materials and nutrients. Mechanitors can use it to produce new mechanoids or to resurrect dead mechanoids. This tier of mech gestator is capable of generating medium, heavy, and ultraheavy mechs.
The process uses harsh chemicals which are stored in toxic wastepacks. Haulers must remove the wastepacks from time to time.

The large mech gestator is a building added by the Biotech DLC that allows for the creation and resurrection of larger mechanoids by a mechanitor


Large mech gestator can be constructed once the Standard mechtech research project, which requires studying a Signal chip gained from Diabolus, has been completed. They require Steel 300 Steel, Component 6 Components, 16,000 ticks (4.44 mins) of work, and a Construction skill of 6.


The large mech gestator is used to build and revive all medium, heavy, and ultraheavy mechanoids. It cannot gestate light mechanoids. Consumes 500 W of power when gestating a mech, and 50 W otherwise. If power is lost during gestation, the cycle will pause, but no other adverse effects will occur. The gestator can only be worked by a mechanitor, and that mechanitor that works the gestator will be bonded to the mechs created.

Allowed mechanoids include:

Some mechs may take multiple gestation cycles. In between each cycle, the mechanitor must initiate the next cycle, which is considered Smithing work.

Resurrection bills are split into the classes and can only be used on dead friendly mechanoids.


Functions identically to the mech gestator, outside of which mechanoids it can gestate, the building's size, and its power consumption.

Most large mechanoids are dedicated for combat. Only tunnelers are able to do work tasks, and even then, it can hold a fair fight. If you don't plan on using the heavier combat mechanoids, then the uses of the large mech gestator are limited.
