There are no zombies inside the robots, however the player is allowed a limited time within the Robot. A piece for the Staff of Wind and an Audio Log can be found inside each Robot. Additionally, when all three of the Robots tread the map at once, only one of the Robots can be entered. It should be noted that only one of the Robots' feet will have the lights lit at a time.

Doing so results in a maintenance hatch opening up that will transport the player to their head when the Robot steps on them. It is possible for a player to enter the inside of a Riese by shooting at the lights on the undersides of their feet. A Robot is capable of killing zombies and downing any players caught in its foot's radius when it takes a step. Lights placed around these areas will flash red when a Robot is about to step down upon the ground. Periodically, they will enter over the map itself, stepping down upon large foot-shaped craters in the ground. In Origins, three Rieses roam the area around where the map takes place. According to Richtofen, building the Rieses was only possible due to Element 115. Two main scientists, Ludvig Maxis and Edward Richtofen contributed to their construction. The Robots were created by Group 935 to help the Central Powers win the Great War. In Gorod Krovi, there are two destroyed Gigants, fallen due to the dragon's attack.

It is later rebuilt and present in Der Eisendrache, where it is destroyed, and later seen outside the map once more. In The Giant, an unfinished Riese is present in the background of the map. There is another fallen Riese to the right of Thor's path. In Origins, there are three Rieses that roam the map, and they are described as 'thousand-foot-tall robot abominations.' Their names are Freya, Odin and Thor, named after three gods in the Norse mythology. There are two types of Giant Robots: the Riese (Giant in German), used by Germany, and the Gigant (Giant in Russian), a copy model used by Soviet Union during World War II.
