Group 935's logo.
Group 935 was a Nazi scientific research group who created the zombies. They were led by Dr. Ludvig Maxis, however there were other known members such as Dr. Richtofen and Sophia. They created the Ray Gun, Wunderwaffe DG-2, Monkey Bomb, Zombies, Hellhounds and teleporters. It is likely they created the Electro-shock Defenses, Perk-a-Cola machines and the Pack-a-Punch machine. They worked in Der Riese (The Giant). Research done on Group 935 wa done by George A. Romero and used to reach a Siberian site (Call of the Dead).
Group 935's main interest seemed to be Element 115 (Unpentium). They ysed it to power their experiments, such as the teleporters. One of their main priorities was to invade Area 51 because it had a large amount of 115. The Wunderwaffe DG-2 was going to be put into mss production, which was intended to help win World War 2. Although their ambitions, very few were made. Their symbol is a hand grabbing an atom with the numbers 935 written in the centre. Two manuals given to 935 members can be found in Der Riese. One of them says
Gentleman,
Allow me to take this opportunity to welcome you into group nine three five. This is a prestigious moment in the history of our race for you represent the future of technological advancement. You are the pioneers of human discovery. In your hands lies the destiny of mankind. In our hands is a great power and with that power comes a price. You have volunteered to be part of this great experiment and with that decision comes the responsibility of absolute secrecy. No one is to know what you do where you work what our research has discovered or what our purpose will be. You will have no further contact with your governments or your families. Your decision to fully dedicate your lives to group nine three five is absolute. In your lockers you will find your field ops manual ( you can find an open copy outside of the map Der Riese, in the building the target of the mission Vendetta walks into in the beginning of the level.) which will direct you should our manifest get compromised. We cannot afford to let this power fall into the wrong hands and therefore the field ops manual should be considered your bible. Make your preparations now, a new dawn is beginning for mankind."
In Kino der Toten, you can find film reels and radios which give progress information on 935.
