Zombie Castle

There once was a castle in Russia. One day the patrol of the castle saw that hundreds of zombies were coming. You had a fight with the zombies. To many of them took the castle. The Russian goverment called the United States Marine Corp(U.S.M.C.) You and the rest of your squad see the castle. As soon as you arrived, no break, no nothing the captain says these six words "We need to retake "Zombie Castle"! Those words haunt your experience there. Can you take it or fail?
