Wet beach adventure

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

Generative artificial intelligence was used during development to create some visual assets in the game. Specifically, AI tools were used to generate certain photo and video content, as well as to assist in the creation of some additional decorative UI and graphic elements. All AI-generated materials were reviewed, edited, and integrated by the developer to fit the game’s artistic style and design.

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.
