Zombie infestation in Heaven's Peak

The Zombie infestation in heavens peak is an event in Overlord and Overlord: Raising Hell. The infestation is caused by Sir William, one of the bosses of the game. He summoned a succubus queen in a search for pleasure and inadvertently caused the plague. The zombies themselves are one of the weakest enemies in game but in large groups they are not to be underestimated.
