Heideltraut is a major antagonist in the 2022 indie horror game The Heilwald Loophole. As the nurse in charge of the sick ward at the ominous Heilwald Klinikum, she presents as a strict, seemingly caring caretaker fiercely protective of her patients. Haunted by her heavy workload and the Klinik’s terrifying experiments, she’s become a wrathful, relentless guardian who pursues intruders with immense strength and thunderous stomps. Though knowledgeable in medicine, her methods are twisted—she’s implied to sedate and neglect patients to keep them quiet rather than heal them. Heideltraut never speaks, yet her presence looms large: she cannot be harmed or escaped from in her domain and will headbutt or throw the protagonist to block progress until you’re caught. Her mutated form and furious defense of the sick ward embody the horrific corruption of the Klinikum’s staff.
