Mainframe Expansion in game

Mainframe Expansions are limited consumable items that allow the player to upgrade their ship attributes by producing an augmentation module. A full stack of these is needed to make a module.

In-game description:

An incomplete part of rerouted military-grade circuitry designed to amplify shipboard instruction. A full stack of these will construct a mountable Augment.


Each of the six main ratings can be upgraded, with each upgrade increasing the rating's value by 20 each time. The cost of upgrading each specific rating increases as it is upgraded, with the first costing one augmentation module (three Mainframe Expansions), the second costing two modules (six Mainframe Expansions), and so on. Each rating can be upgraded up to five times for a total bonus of 100.
