Hilde works for General Hemlock as his chief of security and was sent to clean up Los Perdidos under his orders. She is first seen during a television broadcast with Hemlock, although she is not encountered until Chapter 3.
When Nick Ramos enters the Los Perdidos Police Department Station Parking Garage, he hides behind a broken police car. Nick hears Hilde talking to a few special ops soldiers regarding the security camera footage that Nick came to look for, which she hides in her cleavage.
A civilian man carries his injured wife into the police station garage and asks for help. Once Hilde confirms that there are no other survivors with the man, she orders the special ops soldier to shoot the woman in the head. After the woman has been shot in the head, Hilde snaps the man's neck.
Nick comes out of hiding and tries to reason with Hilde, not believing that she could murder innocent civilians so casually. She orders her special ops soldiers to deal with Nick while she runs up to the third floor of the station.
Nick must chase Hilde to the third floor where he will finally confront her in a boss fight. Nick tackles her, and they both fall out the window. Nick positions himself on Hilde and cushions himself in her breasts. Hilde has died from the fall, as Nick spits out the flash drive.
- When she calls in reinforcements and they break through the windows, upon continuing the fight the windows are not broken.
- She has similarities with Jo Slade from the original Dead Rising, both wear police uniforms and have relations with sexual statements, Jo kidnapping women and sexually assaulting them, and Sgt. Hilde saying several double entendres.
- Hilde is the second female psychopath to sexually harass the protagonist, rather than minor characters.
- Given her appearance, personality and that her mission starts before fellow psychopath Dylan's, Hilde can be mistaken for the psychopath that embodies the deadly sin of Lust. This could have been intentional however, as lust is described as an intense desire for something. Given her enjoyment of killing and fighting, even sexualizing with men, she could represent a lust for violence, and sexualist towards men.
