Rescue Girl Operation: Code X

In 1890, many mutated zombies appeared in abandoned munitions factories in the northern United States. Before that, it was originally a military factory preserved after the First World War, attracting many people to visit. But slowly the people around found that many girls disappeared here. This aroused the great attention of the local government and immediately sealed off the factory. And summoned five star General "McAleavy" to discuss a solution. You, as McLeaver's favorite underling, were sent to the weapons factory to investigate and retrieve the girls if they were found. Are you ready for the mission?
