Walkthroughs for custom maps.

I quickly skimmed through this map in the editor. Looks pretty tough. Prisons with strong heroes in the computer zones + after two months, all gold is taken away daily, meaning by that point you need to gather the Cloak of the Undead King and free Vidomina. Might try playing it sometime.

The map is tough. So far the best result: on 2.2.4 I captured 3 red castles (this allowed him to free all his heroes) and descended through the purple portal into the dungeon with a bunch of Pandora's boxes.
As a result, the army consists of 61 titans, 19 archangels, 264 wizards, and genies with nagas. Stats are 38-31-27-40, and almost all spells, including Town Portal.
And purple has already killed its ally long ago and is advancing from the south on our captured castles.

But what to do next is unclear, since the computers have stats of 70+ and countless troops. Berserk doesn't help, the computer dispels everything immediately.
Gathering the Cloak of the Undead King and freeing Vidomina before the end of month 2 is unrealistic, too many conditions need to be fulfilled to get to her.
