As MM8BDM is created in Zandronum, it shares its extremely flexible modding capabilities. Creating your own levels, gameplay modifications, skins etc is as easy as can be... once you know how to do so.

Running Modifications


Skins can be installed simply by following these steps:

  1. Create a new directory in your MM8BDM folder called "skins".
  2. Extract the wad/pk3 from the skin zip file into the new skins directory.
  3. Launch the game. You should now be able to select your skin from the player setup menu! (NOT the in game selector)

You can use skins online but only those who have the same skin installed will be able to see them.

Everything Else

There are several ways to launch MM8BDM with mods.

MM8BDM Launcher - Using the official launcher you can use "Add File" to add mods to the game.
