Ludvig Maxis

"Greetings. If you are receiving this message, it means that Richtofen has entered the device. If you free me, I will help you minimize the damage that he will inevitably cause."

- Said after Big Bang Theory easter egg is started.

"Regretfully, I must inform you that neither the Earth, nor its people, will survive."

- Said during the "Mined Games" easter egg, after taking control.

Doctor Ludvig Maxis was the lead scientist part of the project known as "Der Riese" and was the father of Samantha Maxis. The player can discover information about him after activating hidden radios. He was the leader of Group 935, aiding in the creation of the Zombies and Hellhounds. Maxis never physically appears in game, but can be heard on several radio/films reels and occasionally while in the teleporter.

As of Buried easter egg Mined Games, if his side is completed, he is the main antagonist of Zombies.

Biography
Doctor Maxis worked with his assistant, Edward Richtofen, at the Waffenfabrik facility codenamed Der Riese located near Breslau, Germany. He was the leader of a secret organization named Group 935. Along with the rest of Group 935, he created the Zombies, Hellhounds and the Teleporters using Element 115. He created the Ray Gun based on plans from Shi No Numa, as well as the 31-79 JGb215, evidenced through quotes said by Richtofen on Shangri-La. As the experiments on Der Riese continued, Maxis became worried about Richtofen as he believed Richtofen was becoming a threat to him and his daughter's lives. Before the zombie outbreak, Maxis was romantically attracted to Sophia, which distracted him from his duties as the Group 935 leader. Richtofen believed Maxis was distracted and was unfit to lead Group 935 and when Richtofen learned that he didn't keep his promise to mass-produce the Wunderwaffe DG-2, Richtofen conspired against him.

Richtofen's Betrayal
Doctor Maxis was working on an experiment with his assistant Edward Richtofen that involved his daughter's pregnant dog named Fluffy. He attempted to teleport Fluffy, but the plan failed. Fluffy teleported but did not return at the Mainframe. She was teleported back to the Teleporter by an electrical force (most probably the ball of electricity players see Hellhounds spawn from in-game). Maxis demanded the door to be opened, but Edward refused. When they finally opened the door, Fluffy had transformed into the first Hellhound. Samantha ran into the room, asking her father, Maxis, what he had done to her dog. The Hellhound began to attack, destroying the room. Maxis tried to calm and reassure his daughter and then tried to escape, but Richtofen locked the door behind him, trapping him and Samantha with the raging Hellhound. Richtofen then activated the Teleporter and Maxis teleported.

Post-Betrayal
Maxis was apparently teleported to a tomb (possibly Shangri-La). Samantha was teleported to Griffin Station and trapped in the M.P.D. Richtofen, realizing that Maxis wasn't dead, told Groph to find him and calm down Samantha. When brought to his daughter, Maxis apologized to her for all that he had done to her, and then told her to kill all the members of Group 935 for betraying him. A gunshot is then heard as Samantha began her killing spree.

Stopping Richtofen's Plan
Due to his suspicions of Richtofen, Maxis had an emergency plan should Richtofen kill him and try and succeed in taking control of the zombies. When Richtofen activated the MPD and entered the Aether by switching his souls with Samantha Maxis, Maxis enlisted the help of Tank Dempsey, Nikolai Belinski, Takeo Masaki and his daughter Samantha (now in Richtofen's former body) to launch three missiles at the Earth, intending to sever the link between the planet and the Aether. Unfortunately, the hasty calculations led to the world's incineration, resulting in the death of millions.

Aftermath
After the Earth's destruction, Maxis, currently an AI-rendered being, then activated his backup plan should his first fail, which was activating global polarization devices to overpower Richtofen and heal the Earth. However, after the disappearance of his daughter, Samantha Maxis, he instead secretly planned to utilize the Aether's energies to destroy the Earth and open the gateway to Agartha, where he believed Samantha was located. Using electronics for communication, Maxis enlisted the assistance of many survivors, whom he used to his advantage, including Abigail "Misty" Briarton, Russman, Marlton Johnson and Samuel Stuhlinger. The four completed a task for him in the cornfields of the Hanford Site, which included the polarizing of a pylon found in the site's cornfields. Following their mission in Washington, Maxis regained contact with the group of survivors after being teleported to Shanghai by Richtofen, where he once again used them to create an energy field to power the polarization device located there.

The Rift


With two of the three polarization devices in effect, Maxis searched the crumbling world to discover the Rift, a series of catacombs in the remnants of Angola where the final polarization device was located. While promising his commorial allies the device would finally heal the Earth, he secretly knew the Rift could supply a direct gateway to Agartha, where a buried western town was entombed.

Outcome 1=If the player decides to follow Maxis' orders in all three Easter Eggs, Maxis will overpower Richtofen and enter the Aether, assuming power over all vital energies that he uses to begin the process of destroying the Earth to open the gateway to Agartha and reunite himself with Samantha. In vengeance against Richtofen, Maxis banishes his soul from the Aether and traps it within a blue-eyed zombie, eternally damning him to walk the Earth as an undead being. Outcome 2= If the player decides to follow Richtofen's orders in all three Easter Eggs, Maxis will be unable to enter the Aether as the energy from the devices is used to strengthen the link between Aether and Earth, granting Richtofen even more power and forcing Maxis to cease existence within his AI form.
