This is a turn-based startegy game with units on a hexfield that you order to fulfill a mission. The gameplay is not unlike Fire Emblem games, but the setting and actual mechanics are different. You have to capture and defend villages in each mission, to gain gold to finance your troops. You can only bring units into battle, which you can pay for. You have different classes of units, each can level up, often with multiple advanced class-options. Different unit-types have different advantages or disadvantages against other unit types. The environment can give boni or mali. So for a mountain level you want to recruit dwarfs, for water levels merfolk.
