Ludvig Maxis

Doctor Maxis was a doctor who was part of the project known as "The Giant" which took place at Der Riese. You can find out about him when you activate five hidden radios. His team were possibly responsible for creating the Hellhounds and Zombies.

Life
Doctor Maxis worked with his assistant, Doctor Edward Advar, and Doctor Richtofen at the Der Riese facility near Breslau. He worked on creating Zombies and Teleportation Devices. His assistant helped him with this and Richtofen created weapons (Wunderwaffe DG-2). It is possible that Maxis was in charge of the whole operation, but it is unknown who actually was. One of the things Maxis would do was to perform experiments and tests though many of these failed.

It is likely that he could be the "Doctor Max" in the radio message in Shi No Numa, with the American in the message having misnamed him.

Death
Doctor Maxis was working on an experiment that involved his daughter's dog called Fluffy. He would attempt to teleport Fluffy, but when he did, the plan failed. Fluffy was teleported, but not to the mainframe. She teleported back inside the Teleporter from an electrical force, most probably the ball of electricity players see Hellhounds spawn from. Maxis demanded the door to be opened, but Edward Advar advised him not to. When they opened the door, Fluffy had transformed into a Hellhound. Samantha came running through, asking her daddy what he had done with her dog. The Hellhound began to try and attack, and began to destroy the room. This caused chaos, and as Maxis tried to calm his daughter down Edward exited and locked the door. Maxis told him to open it, but Edward disobeyed him, and left him and his daughter to be killed by the hound.
