The Volleyball Game is in the level Sand Castle Roof. You have to fight a few waves of Saracens until you reach the game. Once you reach the game, you will see a beach ball in the middle of the court. Hit the ball to the other side of the court and make sure it hits the ground. Repeat this until you get 10 points. If you lose, you can still do it over until you get it right. Once you beat it, you will obtain the Map.
