Dr. Hatzinger

1. Summary

Dr. Hatzinger is a German physician and former Nazi officer who organized and supervised the unethical human experimentation in D3. He is among the most important historical figures within the fictional installation. He was stabbed to death in his office by Dr. Valério, a physician who worked under him, and the institution concealed the murder as an accident.

2. Identity

• Name: Dr. Hatzinger.
• Origin: a German physician; a former Nazi officer associated with Josef Mengele.
• Position: he joined the American research program and played a central role in organizing and supervising unethical experimentation in D3, where he led the scientific leadership responsible for the human experimentation programs.
• Family: he had a family, out of respect for whom his body was not displayed during his funeral.
• Death: killed with a knife in his office by Dr. Valério; the institution reported an accident.

3. Personality

Hatzinger concealed his continued racial convictions after joining the American research program. He privately admired Josef Mengele and Shirō Ishii: his private writings refer to them with disturbing admiration. These references reveal his moral corruption and his deliberate rejection of ethical limits.

He used scientific explanations to justify atrocities, and he manipulated the physicians who worked under him.

4. Background

Hatzinger maintained a private office in D3 containing documents, scientific notes, and personal possessions. The concealed room that reveals his intellectual influences, with its historical portraits, is described with the level. See: Places › D3. What his private writings say is in See: In-World Documents › Hatzinger's Private Writings.

Dr. Valério, a Brazilian physician who worked under him, initially admired him and considered him an extraordinary scientist, then came to see that his scientific explanations were being used to justify atrocities. Valério eventually entered Hatzinger's office and attacked him repeatedly with a knife. The struggle survives only as the audio of a damaged security recording. See: In-World Documents › The Murder Recording.

A newspaper clipping reported his death as an accident. The true circumstances of his death were concealed. See: In-World Documents › Hatzinger's Death Notice.

5. Role in the Story

Hatzinger's private research records are part of the chapter's historical horror. The records of his involvement with the installation also appear in D2's technical archives. His murder is presented as the violent culmination of years of guilt, fear, resentment, and moral collapse in the physician who killed him, without heroic music or celebratory framing. See: Campaign › 6. Gates Of Hell and See: Campaign › 5. Mystery Base.

The game must distinguish between historical fact and its fictional narrative. The presence of the portraits establishes Hatzinger's admiration for real historical perpetrators; it does not imply that they personally participated in the fictional Schwarzwald project. The environment and documents must carry most of the narrative weight.
