Last but not least we come some map work ive done. I don't claim to be any ace campaign writer, but i dabbled in it here or there and learned as i went. Both of these files are add ons to your existing campaing layer. You simply merge them into the campaign_RND.mis, and they become intergrated into your campaing game. These files are compatiable with Unified Campaign Vanilla, and GW11a. NYGM users will have to make some changes the NYGM/data/rooster/English.cfg (or German.cfg) or go through the files and remove all generic entires.
The instructions for NYGM users and how to merge the files are outlined in this thread:
