Posts from Has anyone played through Len’s mission in Heroes of Might and Magic II? Auto-translated

How do I open a GX1 file? I suspect that players weren't playing Len's mission on the portal, as it's impossible to complete it in three days. The victory conditions for this mission are to score 200,000 points or capture all three enemy castles, which is impossible to do in three turns.

The gx1 file should be placed in the Heroes2/Games directory. After that, launch the game, and this save will appear in the Games menu.
The possibilities in the second Heroes game are quite extensive.

I unlocked everything; it really is Len's mission. But I'm still curious how he managed to defeat the Necropolis heroes at the beginning of the game, considering they start with 40 skeletons and the Haste spell.

An army consisting of fairies and single units of centaurs was assembled (the hero Carlawn was in the save file). With the blessing of the fairy, they destroy the skeletons, which are attacking the centaurs first.

Then another question arises: where did they get 55 fairies from? Especially considering it's a Wizard Castle. To gather that many fairies, all heroes would need to have a fairy unit for trading.

I haven't had three level 40 heroes at once yet. All heroes are different. But the main problem isn't even about repelling the initial attack. I could manage that by staying in the castle. The main problem is the Necromancer's advanced magic. They immediately have the Cold Wind spell at the beginning of the game. By the time I reach their stronghold, I barely have an army left. In this regard, Dwarves are good; magic doesn't always affect them.

Sorceresses are not among the starting heroes; they are purchased in the tavern. And the starting conditions should be generated in such a way that the Necropolis doesn't have powerful offensive magic.

I also bought them in the tavern. After collecting all the fairies from all forty heroes, and also from the castle, I only had 40 fairies.
The first three Necromancers only have the speed magic spell. But the second wave of Necromancers always comes with the Cold Ray spell.
It seems that this mission doesn't have a universal walkthrough, and for the most part, everything depends on luck.

Luck has nothing to do with it. Every time you start a new game, the number of fairies in Heroes of Might and Magic and other elements are randomly generated. You just need to restart the game a few times to find the best option for yourself, so that everything suits you.
However, there isn't a single algorithm that works for all starting conditions, and that's true.
