Campaign mode is one of the toughest, yet one of the most rewarding, segments of Dragons of Atlantis: Heirs of the Dragon. Campaign mode is where you fight against Grodz and his minions for ten different levels of play. The Grodz bases start off so easy to beat as to be downright laughable. Gradually, though, they get moderately more difficult, then out of nowhere, they become nearly impossible to beat. They have to be beaten, though, if you want the Dragon Armor.
