Sim Settlements - Conqueror

Update 10/23/2025: The source code is now publicly available on Github for folks interested in learning how it ticks or making patches!

TLDR: Third Official Expansion to Sim Settlements.

Adds the ability to pre-build all of the settlements as NPC-run cities which you can explore, help, or Conquer.

Includes a Raider quest line which unlocks new Perks, Building Plans, and Leaders (Will be expanded throughout the year!)

IMPORTANT: Always be sure you are on the latest version of Sim Settlements and Workshop Framework - both mods include code Conqueror relies on.

Conqueror pushes Sim Settlements into new directions, allowing you to Explore and Conquer, or Build and Destroy (or all of the above). Starting the game with pre-built Cities opens up an entirely new way to look at Fallout 4, and tons of new possibilities for gameplay.

Prefer to build everything yourself? You can still do that, the Conqueror system will be expanding beyond the Raider questline in future patches so you can use it to convert some of your settlements into military outposts to run a Commonwealth army!

This is an Expansion Pack - and will always require the latest version of Sim Settlements and Workshop Framework, whenever you update this, be sure to also update both of those mods.

Overview

At the surface, this expansion appears to be entirely about Raiders. Aesthetically, it definitely is. We decided to fully embrace the visual and even gameplay behind raiders. Though functionally, this expansion will add a ton of possibilities and benefits to all SS players.

Conqueror is about providing new ways to play, both at the beginning of a new game, through the Pre-Built settlements and the Raider questline, and at the end by offering you a way to convert your settlements to operate like military outposts*.

Like the expansions before it, Conqueror will continue to receive bi-weekly updates for the foreseeable future to improve and expand the gameplay based on community feedback.

Workshop Framework

This expansion requires Workshop Framework, though Sim Settlements and the Three-in-One do not. Workshop Framework offers a host of new features Conqueror is taking advantage of, one of which is a much faster threading engine to allow for pre-built City code to run fast enough.
