====== Extensions ======
Extensions are **optional** rules that add to or modify mechanical behavior from those presented in the [[core:start|Core Rules]]. Most [[content-packs:start|Content Packs]] rely on one or more Extensions.

__They:__
  * introduce new systems, not new fiction
  * define resolution methods, constraints, or affordances
  * are setting-agnostic by default
  * may be enabled or disabled independently

__Examples:__
  * Equipment rules
  * Hit locations
  * Social conflict mechanics
  * Vehicles
  * Magic systems
  * Sanity / Stress

Extensions never contain setting-specific lists or lore.

The GM shall determine which Extensions are in use for their game world. A [[checklist|checklist]] is provided that the GM can provide as a handout to players, so they are aware of which Extensions are in use.

> **Extensions never depend on Content Packs.**

This one-way dependency keeps the ecosystem sane forever.

===== Extension Families =====
Extensions are grouped into categories called Families. Although they are grouped this way, a GM may still turn on or off any Family or Extension within a Family as they see fit.
