The mystery of the ancient marshes: the map is certainly challenging. Perhaps to start properly, you need to hire two weak heroes; it would be good if one of them had a specialty for creatures, with Chaos skills, and with imps in their army. Ideally, they would have all of that at once. And for the main hero, I chose Railag. Specifically, Railag. As I understand it, the author unlocked him along with the other heroes from the campaigns (or maybe I have some mods?). As a result, the red player manages to defeat Giovanni, but the blue player, Biara, is shamefully driven away: it's just a little too far, and the heroes don't reach him. But I've only just started, and I'll play more. I already know for sure that if you set the blue player to computer control, the chances are slim. Either play it yourself or with someone else.
In general, the trend of maps featuring allies vs. computer is quite interesting in my opinion.

Also, there are few votes. Is it a joke that 43 people downloaded the file from the Winner's link? + 15 from the forums. And only two people voted, it seems.
