Marcos II- The 23rd Anglican Guard regiment on a cleanse and recover op at one of the many mining outposts on the world to be hit with the zombie plague, defends a ruin from a horde of zombies.  amongst the horde of zombies are many of the PDF troops who were present at the outpost during the initial outbreak.  The unit from the 23rd Anglican holds a good position with a great choke point that should see them hold off the undead horde.
