Does Deadhaus Sonata use AI-generated content?

Yes. The developers disclose AI-generated content on the game's Steam page:

Deadhaus Sonata is created by our team of artists, voice actors, designers, writers, and developers. During an earlier stage of development, AI-assisted tools were used by a former developer that is no longer part of the team, to help create certain HUD elements. These elements are being redesigned, handcrafted, and replaced by our new lead UI/UX Artist. All other in-game content is created by our team.

Self-reported by the developer under Steam rules: it covers AI content that ships in the game, not tools used to make it. Steam page checked on Oct 28, 2026. How to filter AI games on Steam
