Modules

A module is an optional subsystem that bolts onto the chassis. Nothing in the core rules depends on one, and removing it leaves a working game behind.

This is how most engines grow. A module is the unit a designer reaches for when several different games want the same machinery, combat, chases, crafting, factions, and none of them want to write it twice. It names what it adds, what it assumes, and what it touches. If two modules disagree, the table decides which one wins.

Frontiers keeps modules in two sets.

 

Official Modules Written and maintained here Modules built alongside the engine, kept current with each release, and tested against every Ruleset. Attribution for these is simplified: naming the module alongside Frontiers is enough.

Community Modules Made by other designers Modules written by other people and collected here with their permission. They carry their own authors and their own credit, and they are open to submission.

The Beta 2026-2 modules are still readable and their design still holds, but they were written against 2026-2's terms and formulas and need converting before they will run on 1.0. The conversion reference lists everything that changed.
