Our take on The Infectious Madness of Doctor Dekker
The defining mechanic is free-text interrogation: patients answer typed questions through filmed video, while the words chosen can alter future sessions and eventual outcomes.
What is The Infectious Madness of Doctor Dekker?
Play as a psychiatrist treating the patients of the deceased Doctor Dekker while investigating his murder.
The game uses 1600+ filmed video responses, triggered by typed questions, phrases, keywords, or suggested prompts. Patient replies can reveal evidence, open further storylines, and affect future acts and endings. The story unfolds across five therapy sessions, with six main suspects and five side quests. The murderer is selected randomly at the beginning, while decisions influence later sessions. There are no point-and-click puzzles; progress comes from questioning patients, inspecting evidence, and choosing an accusation. Automatic saves prevent rolling back statements. Mature themes include psychological horror, sexual themes, violence, and suicide.
