Christmas Zombie Defense

As always, there is plenty to do before Christmas. Presents, remembering everyone and everything, feeding and grooming the reindeer and harnessing them, and now uninvited guests have arrived. Zombies have decided to drop by, but they turn out to be rather unfriendly guests. What can you do? They will have to be taught a lesson. Santa has taken a gun and gone to shoot the zombies so they will think twice next time. Send all the zombies back to their ghostly world.
