The game mechanics consist of several stages in which the player must defeat the enemy or fulfill other tasks to advance to the next level. Fighting is done in turns, meaning that once the player has moved and attacked, it's the enemy's turn to move his troops one by one. When the battle is won, the next level becomes selectable. Between fights, you can improve your squad of fighters by buying better weapons, recruiting more soldiers and so on.
