When you unlock the door, a medium wave of zombies will pour out the door. The two keys are on the upper floor in the corridor, and on the lower floor in a side room near the safe room. This assault should only last a few minutes, when it ends, return to the first building. Enemies will attack from the left and right of the plaza, including kamakazie zombies. The first is on the upper floor in the side room, and the second is just outside the safe room.Īfter exiting the safe room and returning to the plaza, it starts with a large hoard. The building on the opposite of the plaza opens, and you can find the first two keys there. When you approach the library, the door is locked and you need to find the key. Note that you will revisit the plaza multiple times, thus you may want to leave some equipment for the final battle. Starting at the first floor, the team needs to use the stairs to the top floor, cross to the next room, head down the stairs back to ground floor, and out into the plaza. The enemies will mostly attack in their large number once you are outside, including an Elite Zombie in the attack. The group starts in a tunnel, which is a simple corridor run. The Berlin Central Library contains a medieval occult text that may be the key tp stopping the zombie invasion: The Book of Souls.
