Fortify is a RTS castle defense game. Defend your castle from attacking creatures and eventually their leader Trocles. Starting at the Iron age with only a few slingshooters at your disposal you start getting gold from the attackers. But gold won’t be enough! Construct outposts and send miners to gather lumber, stone and iron to advance through the medieval age and to the imperial age. Each age comes with new ways to defend your castle; oil pits, catapults, cannons, defensive spikes and new units, both ranged and melee with unique abilities.
