Is it possible to make data mods affect campaigns?

I would really like to play the campaigns with the historical accurate mod, but I can only use it in skirmish maps.
Is there a way to make it apply for campaigns too?

Many thanks

You should be able to make it work by copying dat file to “AoE2DE\resources\_common\dat\empires2_x2_p1.dat”. You need to backup original dat file and replace it back for multiplayer games though I believe.

THANK you! Worked like a charm. Now I just have to learn how to mod civilization tech trees so I have access to the units I want in the campaigns :slight_smile:
