Command-Ω Omega 2

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

During the development of this game, artificial intelligence tools were used strictly for pre-generated content. Specifically, AI was utilized to assist with code refinement, the creation of initial concept art, and the design of certain user interface (UI) elements. All AI-assisted assets and code were thoroughly reviewed, modified, and integrated manually to ensure they meet the game's specific style and technical requirements.

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.
