Royal Defense is a strategy game where you place various characters in a scenario to defend your settlement from monsters. To succeed, you'll have to combine characters to get new ones and plant them at each enemy outpost.
Royal Defense has 3D graphics shown from a bird's eye view. Basically, it's up to you to combine identical warriors to unlock stronger ones. After that, you have to decide where to place each of these characters on the battlefield.
Attacks unfold automatically as your enemies advance.
