The game is a multi player Progressive battle arena. The key aspects are fast entertaining battles.
First map structure, it uses a couple of concepts to develop the map structures. Like roads where players can move a little faster to allow building of large extensions of maps.

Resources are missing but that can be tweaked with the map structure.
