Your three heroes: Crassus, Thyreus and Minsthras must traverse different zones in order to get to the end of the map. You must find the Sky Passages that link each zone and kill the enemies surrounding it to get to the next stage.
Each hero has certain strengths and weaknesses; for example, you will find Crassus packs a punch but drops like a sack of multi-grain barley when confronted with anything more than an unarmed washer-woman. OK, so that's not entirely true, but he is certainly the weakest.
You should find yourself adopting certain tactics to stay alive; if you rush in with all your heroes you will most likely have the pleasure of watching them die.
I've worked on this map for a long time now, only on and off, like how I play AoM - I start a phase of it then I move on to another game.
I've made subtle differences according to three difficulties: Easy, Moderate and Hard. for example, less hitpoints and more enemies on Hard whereas on Easy your Heroes are slightly buffed. The timers are still the same on all difficulties however, so don't waste a second!
