The objective is very simple: defeat your enemies and be the last Hero standing. As of this version, there is no continuing story or plot to the game. Each map plays independently of any others, though authors may attempt to preserve and/or advance a central theme.
Depending on the size and complexity of the map, there will be one to five enemy Heroes present. By managing resources, combat troops, and skills, you can become the most powerful Hero and conquer the lands. But be careful, as you build castles, recruit troops, and explore the map, the enemy Heroes are doing the same!
