Players divide and select collections of units, upgrades and enemy units. They compete against each other to repel foul beasts and conquer the places from which they spawn.
The main concept of the game is that each player has a keep from which they send archers, knights and trebuchets to defend and attack. The game sends battering rams, orcs and dragons. The monsters attack through a narrow mountain pass that opens up to a valley with orc strongholds, towers and forts. It also has a dragon mountain lair.
One player reveals buildings, friendly and enemy units and special event cards. That player divides the items into "equal" piles and the remaining players each select a pile. The person who divided the piles gets the remaining pile. Players then take their turns dealing with the good and bad items that they received. Points are scored for destroying enemy monster units and successfully completing a siege on enemy territories.
