During the demo, there is a storyline that shows and tells how Arthur proved himself to be the rightful heir to the throne of England and destined to be the first King of all the Britons when he managed to pull the sword Excalibur from the stone followed by him being joined by Lancelot and Perceval and then Merlin telling all three that they must find The Holy Grail and attain it's power in order for justice to be brought forth into the kingdom and for Arthur to become the first King of all the Britons. When this battery dies, the game will no longer operate. You will be greeted with a blank screen upon power-up. The game has seven different stages and each of them has a different boss enemy to overcome in order for the stage to be completed. If the food or treasure are struck with any player character's weapon, they will be reduced to smaller portions for smaller amounts of health or fewer points.
Players can also gain food or treasure by saving a knight who is being attacked by an enemy.
Players can also gain treasure by defeating the enemies. Players can also mount horses to ride on and make their weapons more effective against the enemies. The horses can only be mounted by jumping onto them. Players can mount an enemy's horse after knocking him off or a horse can be gained if the player finds and gets a giant chessman of a knight. While on a horse, the Attack button is used for the player character to strike his weapon just like on foot while the Jump button is used for the horse to change directions from right to left and vice versa.
