Design a Connected Underground Settlement

Planning Your Layout

Subterranean modules are designed to connect together through valid doorways and multi-floor stair bridges. Before placing stations, sketch out your intended layout on paper or mentally map how rooms will connect. The mod includes 12 underground modules such as barracks, libraries, smithies, and stair bridges specifically designed for this purpose.

Placing Connected Modules

Place your first Blueprint Station and complete construction. Then position additional stations nearby, ensuring doorways align between adjacent modules. The stair bridge modules allow vertical connections between different floor levels, creating a multi-story underground complex.

Expanding Your Base

As you complete each module, the connected rooms form a cohesive underground settlement. Store your Blueprint Stations safely—they retain any deposited items, so you can break them down and move your construction project as your settlement grows. This lets you expand organically without losing progress or materials.
