Walkthroughs for custom maps.

Thank you to everyone who responded. Currently, I am preparing for a battle with Witch King 1; he is located in the north, near the city of Angmar (apparently, the Angmar Witch-king, the main Nazgûl, who cannot be killed by a mortal man who wounded Frodo and almost killed Gandalf during the Battle of the Pelennor Fields, if we believe the director's extended version). Here is where I stopped: https://yadi.sk/d/fireuIlU3JwwrA. I uploaded the save file to Yandex Disk. I upgraded Aragorn; before that, I was thinking of upgrading Gandalf, but I couldn't acquire Clone, Blindness, and Berserker. After studying these spells, it would be tough for the Angmarite. I conducted a trial battle with him; it seems I need to gather troops or replay until Clone and Blindness appear. Once again, thank you all, especially for the translation.
