Invisible Archery

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

Some visual assets and marketing/store artwork were created with the assistance of generative AI tools and then selected, edited, and integrated by the developer. The game does not use live generative AI during gameplay, does not accept player prompts, and does not generate new content at runtime. AI-assisted assets may include in-game icons, UI artwork, promotional images, capsule artwork, and other visual materials.

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.
