StarRailExpress ModPack

🚂 Introduction

StarRailExpress is an expansion pack for Train Murder Mystery, developed by our Catmoon Team. It greatly enriches the base game with new roles, modifiers, maps, modes, and gameplay mechanics.

• Maps – 16 maps in total, including 5 classic train-themed maps, plus many others with unique map-specific mechanics.
• Roles & Modifiers – Includes content from StupidExpress, Noellesroles, Harpy Simple Roles, and some from KinsWathe, along with many original roles we have designed ourselves.
• Game Modes – In addition to the traditional murder mode, we have added a variety of fun casual modes.

This pack is designed for multiplayer sessions of 6 to 42 players (or even more!). By default, at least 6 players are required to start a game. Neutral roles are only enabled when there are 10 or more players, and certain roles have special spawn conditions based on player count or map.
