From the campaign:
Battle against waves of enemies to prevent them from breaching your defense to the heart of the Citadel.
The Defense of the Citadel is a cooperative hero defense board game for 1 to 4 players. In this high fantasy world, you as the hero need to defend the heart of citadel against waves of enemy invasion.
The heart of the Battle Goddess gives life to the Citadel. Waves of evil monsters from darkness are after its divine power.
You have two ways to start your 'Defense of the Citadel' -- 'Scenario' mode and 'Campaign' mode.
'Scenario' has predefined settings, lasts no more than an hour to play, which is perfect when you just want a quick short game. It is the recommended way to get familiar with the rules of the game.
'Campaign' is the opposite with no particular predefined settings. It is a progressive game where you build your Citadel from scratch to an impenetrable fortress. Your performances and decisions through the phases as well as crafted items and wounds, will carry onto the next until you reach the final objective. 'Campaign' is meant for a long game, and you will need to record the status of the game to carry on the game on another day.
The campaign is more than 2.5x funded already and still has 28 days left to go.
