What happens when you take four individuals, from four countries at war, and make them have to survive and protect each other?

ZPTF fell with the main base many years ago, and a new force has taken over. A tyrannical kingdom formed in the east, it has elliminated the undead threat, but it is the undesirable ruling power. With one side, comes an opposing side.

Zombies have overrun the main base of ZPTF. Since then, there has been no form of government left in the now zombie filled Equestria. Good luck surviving everypony.

After the fall of the main base, codename: Maximum, the ponies are on with a challenge greater than before. The zombie ponies have evolved, giving them the ability to fly and use magic. Sequel to the story Code 5.

The zombie apocalypse has come true. Everypony has joined the ZPTF.
