In a departure from most other survival horror games before and after it, Doctor Hauzer lacked any enemies, but the main threat was instead the sentient house that the game takes place in, with the player having to survive the house's traps and solve puzzles.

The game was directed by Kenichiro Hayashi. The game also utilized an early example of cel-shaded art for the character graphics. Both the player character and the environment were rendered entirely in 3D polygons, while allowing the player to switch the view between three different perspectives: third-person, first-person, and a cinematic or overhead view. The game has never been officially released outside Japan, although fan translations exist.Released by Japanese developer Riverhillsoft for the 3DO in 1994, Doctor Hauzer was the first fully 3D survival horror game. Like Alone in the Dark, Doctor Hauzer has been viewed by some sources as a notable step in the early evolution of the survival horror genre. The game garnered mostly favorable opinions regarding its gameplay and the player's ability to change camera views, though reviewers widely disapproved of its short length and slow frame rate. It has enjoyed positive commentary for its sound design and achievement of 3D graphics on a home console. In spite of the game's single region-exclusivity, Doctor Hauzer has been reviewed by several publications outside Japan and has been met with an overall average critical reception. These characteristics were carried over into Riverhillsoft's next game, OverBlood. However, Doctor Hauzer is the first of this genre to include fully 3D environments that the player can explore while freely swapping between third-person, first-person, and top-down perspectives. Doctor Hauzer has stark graphical and gameplay similarities with early titles in the Infogrames survival horror series Alone in the Dark, which feature 3D polygonal characters and objects set against fixed, pre-rendered backgrounds.
