Current questions and answers regarding the map editor.

Hello everyone. As a child, I loved this game and even created my own silly maps because I really enjoyed it back then. Now, I want to create a series of complex maps with a storyline, and I noticed that through modification, you can upload your own campaign. I've already learned the editor quite well and want to create something complete. I'm interested in how to add my fan-made campaign to Heroes 5 and link the leveled-up heroes between missions. I would be very grateful for any help.
