The game is set on an isometric-view layout where players can control a variety of monsters in order to defend their kingdom, attack other countries, collect resources, or recruit other monsters; all with the ultimate goal of becoming the strongest kingdom of the realm.
The key to the development of the kingdom lies not only in the storage of resources or the construction of facilities; players also need to find and collect monsters in order to defend and attack, and be able to seize enough resources to ensure the prosperity of their kingdom.
