HORDE: The Citadel is an add-on to Horde: The Northern Wind. It is a strategy game based around Russian folk stories. The player starts with his/her hero and a few of his warriors setting up a settlement. In the course of the game the player develops his/her city economically and builds an army to protect his/her country from aggressive neighbors.
In the beginning the player’s army is small, and he/she tries to keep the fragile peace with other nations. But at length he/she becomes strong enough to attack and conquer those, who once were a menace to his/her land.
