Installing mods in base main campaign?

Hi everyone.

I wanted to ask if it is possible to add mods in the base main game, such as alternative music?

I have looked around but other than custom maps, I couldn’t find something about that.

Thank you in advance :smiley:

It may still be possible. You just make a mod, the adjustments you want, while keeping all the files of vanilla, then build. Then rename your mod’s .arz into “database.arz”, and replace it in the main game folder. I haven’t considered the expansion folder; it should be similar process.

Yes, this should work. It’s extremely important to mention however that you must include all the original vanilla files with your mod otherwise you will break your game by overwriting the vanilla files with mod files.
