THD Runtime Rules

THD Runtime Rules is a pack-specific component for The Hundredth Dawn, a cooperative urban survival experience for Minecraft 1.20.1.

It applies THD survival and combat rules, persistent progression, checkpoint restoration, horde and roster behavior, and compatibility adjustments. It works with the THD datapacks and matching THD Online component.

This is not a standalone content mod. Install it through the matching The Hundredth Dawn modpack with its required mods and configurations. Using it alone or mixing releases is not supported.

This upload preserves the existing 2.1.8 runtime JAR. Its runtime and bridge components share one JAR; no duplicate installation is needed. The existing All Rights Reserved license is retained. THD source code is not included.
