The most challenging maps for you.

When I finally stopped hesitating and “snickered,” :) I realized what I was doing wrong: I rearranged the stacks of archers so that the snipers were approximately in the middle. Now, of course, everything became clear: here is my first result, naturally not the best (it’s a pity for the archangels!), but achieving a perfect victory here is no longer necessary for me – the main outcome is important. Yes, there are many spells and techniques in "Heroes" that I rarely use or almost never use, and I seem to have forgotten about the Force Field, but here it is – exactly what the doctor ordered. But now I can redeem myself in the eyes of the players: it’s still a shame, because I’m not such a noob after all! :)
And in general, I repeat, I really liked the "Undead Apocalypse" map, I recommend it to everyone who loves difficult maps, and not just “mowing down,” but those where you need to figure out how to act.
