WHAT IS THE LIMINAL HORROR SRD V3.0?
This system reference document is a collection of mechanics, rules, and content that can be used by designers to freely make and publish ttrpg products that are compatible with the Liminal Horror RPG. Liminal Horror at its base is a rules-lite, adaptable survival-horror roleplaying game about normal characters and their struggles against monsters that haunt the night. The game focuses on surviving the weird and investigating horrors, blending simple, old-school inspired rules with modern, narrative first principles.
This SRD is aimed at designers, writers, and publishers who’d like to create adventures and scenarios for the Liminal Horror system. This document includes items that can be used in publications either directly, or as exemplars with accompanying design commentary to help write your own versions.
The System Reference Document lives in the SRD section of the website: https://liminalhorrorrpg.com/srd/
