The fourth Nazi Zombie map is Der Reise, which stands for the giant. This map has a few new additions. The first new items that were put on this map were monkey bombs. You can get these from opening the box. When this bomb is thrown the monkey starts playing his cymbals and the zombies are attracted to it so they go to it, then the monkey blows up and kills them. The new major thing on this map is the teleporters. You can link these to the main frame and they create another way to escape the zombies. You can also make your weapons very powerful when you “Pack-a-Punch” them, a new addition to the map.
