In this game, you need to fight monsters in small arenas, where you place mercenaries, and then watch the battle.
Sounds simple, but in fact, it is important who and where you place before the battle. Planning is the most important part of the battle.
You will have to fight against various opponents who are able to attack both close and from afar.
Some enemies explode when they are near your soldiers, some are able to heal, and someone creates new enemies.
