In this independent expansion, players will go to Berlin Central Library to retrieve the Book of Soul, which is an item to stop the zombie army. Players have to go through the village of death, the cathedral, the depths of the underground and the Berlin Central Library. Finally, we will arrive at the dock through the subway station and send a boat to pick up the team members.

Berlin Central Library is located on the right side of Berlin Square. In the original book, there are many blockhouses and other large fortifications around the library. These settings were cancelled in the army of zombies.

There is a book of souls in the library. If you get it, you can deal with the undead.

The safe house appears at the location specified by the mission. After arriving at the safe house, players are no longer attacked by zombies. There are a lot of guns, ammunition and props in the safe room, and players can prepare in the safe room. Open the door on the other side of the safe house and the player can continue to complete the task.
