I usually use Archers and mages next to each other, upgrade them and the buy cannons. I upgrade the cannons and help with any meteors or reinforces I can use. Hope my stategy helped
@bizax97:maybe you should beat all the levels in normal models with 3 stars(your encyclopedia will be updated) or the heroic/iron challenges. whatever, i did. BTW, i beat the new level of the ruins(all models)
I have completed all the levels with 3 stars, and at heroic and iron levels, and i have a full encyclopedia, but the ruins of acaroth is still locked. What do i need to do to unlock it?
