Titanic Escape Simulator™

The developers describe how their game uses AI generated content like this:

Our game uses pre-generated AI content exclusively for audio production. Specifically, we utilize generative AI tools to assist in the creation of our background music tracks and to generate voice-over (VO) dialogue for characters. All AI-assisted audio is pre-rendered during development and baked into the final game files. We do not use live-generated AI at runtime, and we do not use generative AI for visual artwork, 3D models, code, or the written narrative.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
