Multiplayer social deduction has always been a natural fit for Minecraft, and Wathe Murder Mystery Mod delivers exactly the framework needed to make it happen. Built as the core engine behind the Last Voyage of the Harpy Express experience, this Fabric mod handles everything from hidden role assignment to round management — giving map creators a complete toolkit for crafting their own murder mystery scenarios. If you enjoy games like Among Us or Mafia but want that experience inside your blocky world, this mod lays the groundwork.
Key Features
- Hidden Role System — Players receive secret roles at the start of each round, each with unique abilities and objectives. Map makers and addon creators can also introduce custom roles to expand the gameplay.
- Full Round Lifecycle Management — The mod controls the entire game flow including start conditions, player requirements, round timers, and win/loss conditions, so hosts don't need to manage anything manually.
- Task & Objective System — Players can be assigned tasks during a round that influence mechanics such as sanity or overall progression, adding strategic depth beyond simple deduction.
- Map Interaction Framework — Allows custom maps to trigger special gameplay events like giving keys or items, activating scripted sequences, and setting environmental effects to build atmosphere.
- Modular Design for Map Creators — Serves as a flexible foundation that lets builders design entirely custom social deduction experiences without coding a game engine from scratch.

FAQ
Can I play Wathe Murder Mystery Mod in singleplayer?
The mod is designed as a multiplayer social deduction framework, so it requires multiple players to function as intended. You will need a server or LAN world with other participants to run a proper game.
Does Wathe Murder Mystery Mod work with Forge or NeoForge?
No. This mod is built exclusively for the Fabric mod loader and requires Fabric API as a dependency. There is no Forge or NeoForge version available.
Do I need a special map to use this mod?
Yes. Wathe Murder Mystery Mod provides the underlying game systems — role assignment, round management, tasks — but it needs a compatible map to deliver a full playable experience. The Last Voyage of the Harpy Express is the primary map designed for it.
