G'Express

G'Express is a community-made addon for Wathe and Wathe: Extended, designed specifically for The Harpy Express: Extended Modpack.

This mod was created for our community Harpy Express server. The server has no affiliation with doctor4t other than using the foundations of their mods and maps, and some features are built around our own custom server setup rather than general-purpose Wathe servers.

G'Express adds new roles, modifiers, items, map tools, train tools, host settings, and gameplay systems for custom murder mystery rounds aboard the Harpy Express.

Using this mod outside of The Harpy Express: Extended may work, but it is not the intended environment.

The mod is mainly recommended to be used on our community server, where regular game nights are hosted with different roles and modifiers. The link to the community discord is here G'Express
