HordePlusLite – Server Only Mod for Mordhau (Discontinued)

A simple Server only Mod that gives Casual Vanilla Horde experience.
This is designed for my Chinese friend Cabbageman3, his server and his group people.
Since mod.io is restricted from China to connect, Chinese cannot join servers with properly subscribed mods.
If you are also in the same condition, or just want to preserve your horde server as vanilla server, feel free to adopt this mod.
What the server owner needs to do is set up the mod manually and load the actor.
Thereby, clients do not have to download any but enjoy the mod features.

Installation

1. Manually download the zip compressed Mod.

2. Extract it and put HordePlusLite.pak to the server directory.

For Linux : Mordhau/Content/Paks
For Windows : Mordhau\Content\Paks
