Battle Of Plans

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

Some of the art assets in Battle of Plans were produced with AI-assisted tools. Specifically, a number of 3D props (weapon models) were created using AI-assisted 3D generation and then manually retopologized, re-textured and integrated by our team, and some promotional/store images were created with AI image tools. Every AI-assisted asset was reviewed by a human before it shipped. Localization into languages other than Turkish and English was produced with machine translation. The game does not generate any content while you play: there is no AI chat, no AI-generated dialogue, and no runtime asset generation. Player chat is written by players and filtered server-side.

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.
